DESCRIPTION

       lvcreate  creates  a  new LV in a VG. For standard LVs, this requires allocating logical extents from the
       VG's free physical extents. If there is not enough free space, the VG can  be  extended  with  other  PVs
       (vgextend(8)), or existing LVs can be reduced or removed (lvremove(8), lvreduce(8).)

       To  control  which  PVs  a  new  LV  will use, specify one or more PVs as position args at the end of the
       command line. lvcreate will allocate physical extents only from the specified PVs.

       lvcreate can also create snapshots of existing LVs, e.g. for backup purposes. The data in a new  snapshot
       LV represents the content of the original LV from the time the snapshot was created.

       RAID  LVs  can  be created by specifying an LV type when creating the LV (see lvmraid(7)). Different RAID
       levels require different numbers of unique PVs be available in the VG for allocation.

       Thin pools (for thin provisioning) and cache pools (for caching) are  represented  by  special  LVs  with
       types  thin-pool and cache-pool (see lvmthin(7) and lvmcache(7)). The pool LVs are not usable as standard
       block devices, but the LV names act as references to the pools.

       Thin LVs are thinly provisioned from a thin pool, and are created with  a  virtual  size  rather  than  a
       physical  size.  A  cache  LV is the combination of a standard LV with a cache pool, used to cache active
       portions of the LV to improve performance.

       VDO LVs are also provisioned volumes from a VDO pool, and are created with a virtual size rather  than  a
       physical size (see lvmvdo(7)).

   Usage notes
       In  the  usage  section below, --size Size can be replaced with --extents Number. See descriptions in the
       options section.

       In the usage section below, --name is omitted from the required options,  even  though  it  is  typically
       used.  When  the  name  is  not specified, a new LV name is generated with the "lvol" prefix and a unique
       numeric suffix.

       In the usage section below, when creating a pool and the  name  is  omitted  the  new  LV  pool  name  is
       generated with the "vpool" for vdo-pools  for prefix and a unique numeric suffix.

       Pool name can be specified together with VG name i.e.: vg00/mythinpool.

OPTIONS

       -a|--activate y|n|ay
              Controls the active state of the new LV.  y makes the LV active, or available.  New LVs are made
              active by default.  n makes the LV inactive, or unavailable, only when possible.  In some cases,
              creating an LV requires it to be active.  For example, COW snapshots of an active origin LV can
              only be created in the active state (this does not apply to thin snapshots).  The --zero option
              normally requires the LV to be active.  If autoactivation ay is used, the LV is only activated if
              it matches an item in lvm.conf activation/auto_activation_volume_list.  ay implies --zero n and
              --wipesignatures n.  See lvmlockd(8) for more information about activation options for shared VGs.

       --addtag Tag
              Adds a tag to a PV, VG or LV. This option can be repeated to add multiple tags at once. See lvm(8)
              for information about tags.

       --alloc contiguous|cling|cling_by_tags|normal|anywhere|inherit
              Determines the allocation policy when a command needs to allocate Physical Extents (PEs) from the
              VG. Each VG and LV has an allocation policy which can be changed with vgchange/lvchange, or
              overriden on the command line.  normal applies common sense rules such as not placing parallel
              stripes on the same PV.  inherit applies the VG policy to an LV.  contiguous requires new PEs be
              placed adjacent to existing PEs.  cling places new PEs on the same PV as existing PEs in the same
              stripe of the LV.  If there are sufficient PEs for an allocation, but normal does not use them,
              anywhere will use them even if it reduces performance, e.g. by placing two stripes on the same PV.
              Optional positional PV args on the command line can also be used to limit which PVs the command
              will use for allocation.  See lvm(8) for more information about allocation.

       -A|--autobackup y|n
              Specifies if metadata should be backed up automatically after a change.  Enabling this is strongly
              advised! See vgcfgbackup(8) for more information.

       -H|--cache
              Specifies the command is handling a cache LV or cache pool.  See --type cache and --type
              cache-pool.  See lvmcache(7) for more information about LVM caching.

       --cachemetadataformat auto|1|2
              Specifies the cache metadata format used by cache target.

       --cachemode writethrough|writeback|passthrough
              Specifies when writes to a cache LV should be considered complete.  writeback considers a write
              complete as soon as it is stored in the cache pool.  writethough considers a write complete only
              when it has been stored in both the cache pool and on the origin LV.  While writethrough may be
              slower for writes, it is more resilient if something should happen to a device associated with the
              cache pool LV. With passthrough, all reads are served from the origin LV (all reads miss the
              cache) and all writes are forwarded to the origin LV; additionally, write hits cause cache block
              invalidates. See lvmcache(7) for more information.

       --cachepolicy String
              Specifies the cache policy for a cache LV.  See lvmcache(7) for more information.

       --cachepool LV
              The name of a cache pool.

       --cachesettings String
              Specifies tunable values for a cache LV in "Key = Value" form.  Repeat this option to specify
              multiple values.  (The default values should usually be adequate.)  The special string value
              default switches settings back to their default kernel values and removes them from the list of
              settings stored in LVM metadata.  See lvmcache(7) for more information.

       -c|--chunksize Size[k|UNIT]
              The size of chunks in a snapshot, cache pool or thin pool.  For snapshots, the value must be a
              power of 2 between 4KiB and 512KiB and the default value is 4.  For a cache pool the value must be
              between 32KiB and 1GiB and the default value is 64.  For a thin pool the value must be between
              64KiB and 1GiB and the default value starts with 64 and scales up to fit the pool metadata size
              within 128MiB, if the pool metadata size is not specified.  The value must be a multiple of 64KiB.
              See lvmthin(7) and lvmcache(7) for more information.

       --commandprofile String
              The command profile to use for command configuration.  See lvm.conf(5) for more information about
              profiles.

       --compression y|n
              Controls whether compression is enabled or disable for VDO volume.  See lvmvdo(7) for more
              information about VDO usage.

       --config String
              Config settings for the command. These override lvm.conf settings.  The String arg uses the same
              format as lvm.conf, or may use section/field syntax.  See lvm.conf(5) for more information about
              config.

       -C|--contiguous y|n
              Sets or resets the contiguous allocation policy for LVs.  Default is no contiguous allocation
              based on a next free principle.  It is only possible to change a non-contiguous allocation policy
              to contiguous if all of the allocated physical extents in the LV are already contiguous.

       -d|--debug ...
              Set debug level. Repeat from 1 to 6 times to increase the detail of messages sent to the log file
              and/or syslog (if configured).

       --deduplication y|n
              Controls whether deduplication is enabled or disable for VDO volume.  See lvmvdo(7) for more
              information about VDO usage.

       --discards passdown|nopassdown|ignore
              Specifies how the device-mapper thin pool layer in the kernel should handle discards.  ignore
              causes the thin pool to ignore discards.  nopassdown causes the thin pool to process discards
              itself to allow reuse of unneeded extents in the thin pool.  passdown causes the thin pool to
              process discards itself (like nopassdown) and pass the discards to the underlying device.  See
              lvmthin(7) for more information.

       --driverloaded y|n
              If set to no, the command will not attempt to use device-mapper.  For testing and debugging.

       --errorwhenfull y|n
              Specifies thin pool behavior when data space is exhausted.  When yes, device-mapper will
              immediately return an error when a thin pool is full and an I/O request requires space.  When no,
              device-mapper will queue these I/O requests for a period of time to allow the thin pool to be
              extended.  Errors are returned if no space is available after the timeout.  (Also see dm-thin-pool
              kernel module option no_space_timeout.)  See lvmthin(7) for more information.

       -l|--extents Number[PERCENT]
              Specifies the size of the new LV in logical extents.  The --size and --extents options are
              alternate methods of specifying size.  The total number of physical extents used will be greater
              when redundant data is needed for RAID levels.  An alternate syntax allows the size to be
              determined indirectly as a percentage of the size of a related VG, LV, or set of PVs. The suffix
              %VG denotes the total size of the VG, the suffix %FREE the remaining free space in the VG, and the
              suffix %PVS the free space in the specified PVs.  For a snapshot, the size can be expressed as a
              percentage of the total size of the origin LV with the suffix %ORIGIN (100%ORIGIN provides space
              for the whole origin).  When expressed as a percentage, the size defines an upper limit for the
              number of logical extents in the new LV. The precise number of logical extents in the new LV is
              not determined until the command has completed.

       -h|--help
              Display help text.

       -K|--ignoreactivationskip
              Ignore the "activation skip" LV flag during activation to allow LVs with the flag set to be
              activated.

       --ignoremonitoring
              Do not interact with dmeventd unless --monitor is specified.  Do not use this if dmeventd is
              already monitoring a device.

       --lockopt String
              Used to pass options for special cases to lvmlockd.  See lvmlockd(8) for more information.

       --longhelp
              Display long help text.

       -j|--major Number
              Sets the major number of an LV block device.

       --[raid]maxrecoveryrate Size[k|UNIT]
              Sets the maximum recovery rate for a RAID LV.  The rate value is an amount of data per second for
              each device in the array.  Setting the rate to 0 means it will be unbounded.  See lvmraid(7) for
              more information.

       --metadataprofile String
              The metadata profile to use for command configuration.  See lvm.conf(5) for more information about
              profiles.

       --minor Number
              Sets the minor number of an LV block device.

       --[raid]minrecoveryrate Size[k|UNIT]
              Sets the minimum recovery rate for a RAID LV.  The rate value is an amount of data per second for
              each device in the array.  Setting the rate to 0 means it will be unbounded.  See lvmraid(7) for
              more information.

       --mirrorlog core|disk
              Specifies the type of mirror log for LVs with the "mirror" type (does not apply to the "raid1"
              type.)  disk is a persistent log and requires a small amount of storage space, usually on a
              separate device from the data being mirrored.  core is not persistent; the log is kept only in
              memory.  In this case, the mirror must be synchronized (by copying LV data from the first device
              to others) each time the LV is activated, e.g. after reboot.  mirrored is a persistent log that is
              itself mirrored, but should be avoided. Instead, use the raid1 type for log redundancy.

       -m|--mirrors Number
              Specifies the number of mirror images in addition to the original LV image, e.g. --mirrors 1 means
              there are two images of the data, the original and one mirror image.  Optional positional PV args
              on the command line can specify the devices the images should be placed on.  There are two
              mirroring implementations: "raid1" and "mirror".  These are the names of the corresponding LV
              types, or "segment types".  Use the --type option to specify which to use (raid1 is default, and
              mirror is legacy) Use lvm.conf global/mirror_segtype_default and global/raid10_segtype_default to
              configure the default types.  See the --nosync option for avoiding initial image synchronization.
              See lvmraid(7) for more information.

       --monitor y|n
              Start (yes) or stop (no) monitoring an LV with dmeventd.  dmeventd monitors kernel events for an
              LV, and performs automated maintenance for the LV in reponse to specific events.  See dmeventd(8)
              for more information.

       -n|--name String
              Specifies the name of a new LV.  When unspecified, a default name of "lvol#" is generated, where #
              is a number generated by LVM.

       --nolocking
              Disable locking.

       --nosync
              Causes the creation of mirror, raid1, raid4, raid5 and raid10 to skip the initial synchronization.
              In case of mirror, raid1 and raid10, any data written afterwards will be mirrored, but the
              original contents will not be copied. In case of raid4 and raid5, no parity blocks will be
              written, though any data written afterwards will cause parity blocks to be stored.  This is useful
              for skipping a potentially long and resource intensive initial sync of an empty
              mirror/raid1/raid4/raid5 and raid10 LV.  This option is not valid for raid6, because raid6 relies
              on proper parity (P and Q Syndromes) being created during initial synchronization in order to
              reconstruct proper user date in case of device failures.  raid0 and raid0_meta do not provide any
              data copies or parity support and thus do not support initial synchronization.

       --noudevsync
              Disables udev synchronisation. The process will not wait for notification from udev. It will
              continue irrespective of any possible udev processing in the background. Only use this if udev is
              not running or has rules that ignore the devices LVM creates.

       -p|--permission rw|r
              Set access permission to read only r or read and write rw.

       -M|--persistent y|n
              When yes, makes the specified minor number persistent.

       --poolmetadatasize Size[m|UNIT]
              Specifies the size of the new pool metadata LV.

       --poolmetadataspare y|n
              Enable or disable the automatic creation and management of a spare pool metadata LV in the VG. A
              spare metadata LV is reserved space that can be used when repairing a pool.

       --profile String
              An alias for --commandprofile or --metadataprofile, depending on the command.

       -q|--quiet ...
              Suppress output and log messages. Overrides --debug and --verbose.  Repeat once to also suppress
              any prompts with answer 'no'.

       -r|--readahead auto|none|Number
              Sets read ahead sector count of an LV.  auto is the default which allows the kernel to choose a
              suitable value automatically.  none is equivalent to zero.

       -R|--regionsize Size[m|UNIT]
              Size of each raid or mirror synchronization region.  lvm.conf activation/raid_region_size can be
              used to configure a default.

       --reportformat basic|json
              Overrides current output format for reports which is defined globally by the report/output_format
              setting in lvm.conf.  basic is the original format with columns and rows.  If there is more than
              one report per command, each report is prefixed with the report name for identification. json
              produces report output in JSON format. See lvmreport(7) for more information.

       -k|--setactivationskip y|n
              Persistently sets (yes) or clears (no) the "activation skip" flag on an LV.  An LV with this flag
              set is not activated unless the --ignoreactivationskip option is used by the activation command.
              This flag is set by default on new thin snapshot LVs.  The flag is not applied to deactivation.
              The current value of the flag is indicated in the lvs lv_attr bits.

       -L|--size Size[m|UNIT]
              Specifies the size of the new LV.  The --size and --extents options are alternate methods of
              specifying size.  The total number of physical extents used will be greater when redundant data is
              needed for RAID levels.

       -s|--snapshot
              Create a snapshot. Snapshots provide a "frozen image" of an origin LV.  The snapshot LV can be
              used, e.g. for backups, while the origin LV continues to be used.  This option can create a COW
              (copy on write) snapshot, or a thin snapshot (in a thin pool.)  Thin snapshots are created when
              the origin is a thin LV and the size option is NOT specified. Thin snapshots share the same blocks
              in the thin pool, and do not allocate new space from the VG.  Thin snapshots are created with the
              "activation skip" flag, see --setactivationskip.  A thin snapshot of a non-thin "external origin"
              LV is created when a thin pool is specified. Unprovisioned blocks in the thin snapshot LV are read
              from the external origin LV. The external origin LV must be read-only.  See lvmthin(7) for more
              information about LVM thin provisioning.  COW snapshots are created when a size is specified. The
              size is allocated from space in the VG, and is the amount of space that can be used for saving COW
              blocks as writes occur to the origin or snapshot.  The size chosen should depend upon the amount
              of writes that are expected; often 20% of the origin LV is enough. If COW space runs low, it can
              be extended with lvextend (shrinking is also allowed with lvreduce.)  A small amount of the COW
              snapshot LV size is used to track COW block locations, so the full size is not available for COW
              data blocks.  Use lvs to check how much space is used, and see --monitor to to automatically
              extend the size to avoid running out of space.

       -i|--stripes Number
              Specifies the number of stripes in a striped LV. This is the number of PVs (devices) that a
              striped LV is spread across. Data that appears sequential in the LV is spread across multiple
              devices in units of the stripe size (see --stripesize). This does not change existing allocated
              space, but only applies to space being allocated by the command.  When creating a RAID 4/5/6 LV,
              this number does not include the extra devices that are required for parity. The largest number
              depends on the RAID type (raid0: 64, raid10: 32, raid4/5: 63, raid6: 62), and when unspecified,
              the default depends on the RAID type (raid0: 2, raid10: 2, raid4/5: 3, raid6: 5.)  To stripe a new
              raid LV across all PVs by default, see lvm.conf allocation/raid_stripe_all_devices.

       -I|--stripesize Size[k|UNIT]
              The amount of data that is written to one device before moving to the next in a striped LV.

       -t|--test
              Run in test mode. Commands will not update metadata.  This is implemented by disabling all
              metadata writing but nevertheless returning success to the calling function. This may lead to
              unusual error messages in multi-stage operations if a tool relies on reading back metadata it
              believes has changed but hasn't.

       -T|--thin
              Specifies the command is handling a thin LV or thin pool.  See --type thin, --type thin-pool, and
              --virtualsize.  See lvmthin(7) for more information about LVM thin provisioning.

       --thinpool LV
              The name of a thin pool LV.

       --type linear|striped|snapshot|mirror|raid|thin|cache|vdo|thin-pool|cache-pool|vdo-pool
              The LV type, also known as "segment type" or "segtype".  See usage descriptions for the specific
              ways to use these types.  For more information about redundancy and performance (raid<N>, mirror,
              striped, linear) see lvmraid(7).  For thin provisioning (thin, thin-pool) see lvmthin(7).  For
              performance caching (cache, cache-pool) see lvmcache(7).  For copy-on-write snapshots (snapshot)
              see usage definitions.  For VDO (vdo) see lvmvdo(7).  Several commands omit an explicit type
              option because the type is inferred from other options or shortcuts (e.g. --stripes, --mirrors,
              --snapshot, --virtualsize, --thin, --cache, --vdo).  Use inferred types with care because it can
              lead to unexpected results.

       --vdo
              Specifies the command is handling VDO LV.  See --type vdo.  See lvmvdo(7) for more information
              about VDO usage.

       --vdopool LV
              The name of a VDO pool LV.  See lvmvdo(7) for more information about VDO usage.

       -v|--verbose ...
              Set verbose level. Repeat from 1 to 4 times to increase the detail of messages sent to stdout and
              stderr.

       --version
              Display version information.

       -V|--virtualsize Size[m|UNIT]
              The virtual size of a new thin LV.  See lvmthin(7) for more information about LVM thin
              provisioning.  Using virtual size (-V) and actual size (-L) together creates a sparse LV.
              lvm.conf global/sparse_segtype_default determines the default segment type used to create a sparse
              LV.  Anything written to a sparse LV will be returned when reading from it.  Reading from other
              areas of the LV will return blocks of zeros.  When using a snapshot to create a sparse LV, a
              hidden virtual device is created using the zero target, and the LV has the suffix _vorigin.
              Snapshots are less efficient than thin provisioning when creating large sparse LVs (GiB).

       -W|--wipesignatures y|n
              Controls detection and subsequent wiping of signatures on new LVs.  There is a prompt for each
              signature detected to confirm its wiping (unless --yes is used to override confirmations.)  When
              not specified, signatures are wiped whenever zeroing is done (see --zero). This behaviour can be
              configured with lvm.conf allocation/wipe_signatures_when_zeroing_new_lvs.  If blkid wiping is used
              (lvm.conf allocation/use_blkid_wiping) and LVM is compiled with blkid wiping support, then the
              blkid(8) library is used to detect the signatures (use blkid -k to list the signatures that are
              recognized).  Otherwise, native LVM code is used to detect signatures (only MD RAID, swap and LUKS
              signatures are detected in this case.)  The LV is not wiped if the read only flag is set.

       -y|--yes
              Do not prompt for confirmation interactively but always assume the answer yes. Use with extreme
              caution.  (For automatic no, see -qq.)

       -Z|--zero y|n
              Controls zeroing of the first 4KiB of data in the new LV.  Default is y.  Snapshot COW volumes are
              always zeroed.  For thin pools, this controls zeroing of provisioned blocks.  LV is not zeroed if
              the read only flag is set.  Warning: trying to mount an unzeroed LV can cause the system to hang.

VARIABLES

       VG
              Volume Group name.  See lvm(8) for valid names.  For lvcreate, the required VG positional arg  may
              be omitted when the VG name is included in another option, e.g. --name VG/LV.

       LV
              Logical  Volume name.  See lvm(8) for valid names.  An LV positional arg generally includes the VG
              name and LV name, e.g. VG/LV.  LV followed by _<type> indicates that an LV of the  given  type  is
              required. (raid represents raid<N> type)

       PV
              Physical  Volume  name,  a  device  path under /dev.  For commands managing physical extents, a PV
              positional arg generally accepts a suffix indicating a range  (or  multiple  ranges)  of  physical
              extents  (PEs). When the first PE is omitted, it defaults to the start of the device, and when the
              last PE is omitted it defaults to end.  Start and end range (inclusive): PV[:PE-PE]...  Start  and
              length range (counting from 0): PV[:PE+PE]...

       String
              See the option description for information about the string content.

       Size[UNIT]
              Size is an input number that accepts an optional unit.  Input units are always treated as base two
              values, regardless of capitalization, e.g. 'k' and 'K' both refer to 1024.  The default input unit
              is  specified  by  letter,  followed  by  |UNIT.   UNIT  represents  other  possible  input units:
              bBsSkKmMgGtTpPeE.  b|B is bytes, s|S is sectors of 512 bytes, k|K is kilobytes, m|M is  megabytes,
              g|G  is  gigabytes,  t|T  is  terabytes,  p|P  is petabytes, e|E is exabytes.  (This should not be
              confused with the output control --units, where capital letters mean multiple of 1000.)

ENVIRONMENT VARIABLES

       See lvm(8) for information about environment  variables  used  by  lvm.   For  example,  LVM_VG_NAME  can
       generally be substituted for a required VG parameter.

EXAMPLES

       Create a striped LV with 3 stripes, a stripe size of 8KiB and a size of 100MiB.  The LV name is chosen by
       lvcreate.
       lvcreate -i 3 -I 8 -L 100m vg00

       Create a raid1 LV with two images, and a useable size of 500 MiB. This operation  requires  two  devices,
       one for each mirror image. RAID metadata (superblock and bitmap) is also included on the two devices.
       lvcreate --type raid1 -m1 -L 500m -n mylv vg00

       Create  a  mirror  LV  with  two  images,  and  a useable size of 500 MiB.  This operation requires three
       devices: two for mirror images and one for a disk log.
       lvcreate --type mirror -m1 -L 500m -n mylv vg00

       Create a mirror LV with 2 images, and a useable size of 500  MiB.   This  operation  requires  2  devices
       because the log is in memory.
       lvcreate --type mirror -m1 --mirrorlog core -L 500m -n mylv vg00

       Create a copy-on-write snapshot of an LV:
       lvcreate --snapshot --size 100m --name mysnap vg00/mylv

       Create  a  copy-on-write  snapshot with a size sufficient for overwriting 20% of the size of the original
       LV.
       lvcreate -s -l 20%ORIGIN -n mysnap vg00/mylv

       Create a sparse LV with 1TiB of virtual space, and actual space just under 100MiB.
       lvcreate --snapshot --virtualsize 1t --size 100m --name mylv vg00

       Create a linear LV with a usable size of 64MiB on specific physical extents.
       lvcreate -L 64m -n mylv vg00 /dev/sda:0-7 /dev/sdb:0-7

       Create a RAID5 LV with a usable size of 5GiB, 3 stripes, a stripe size of  64KiB,  using  a  total  of  4
       devices (including one for parity).
       lvcreate --type raid5 -L 5G -i 3 -I 64 -n mylv vg00

       Create a RAID5 LV using all of the free space in the VG and spanning all the PVs in the VG (note that the
       command will fail if there are more than 8 PVs in the VG, in which case -i 7 must be used to get  to  the
       current maximum of 8 devices including parity for RaidLVs).
       lvcreate --config allocation/raid_stripe_all_devices=1
              --type raid5 -l 100%FREE -n mylv vg00

       Create  RAID10 LV with a usable size of 5GiB, using 2 stripes, each on a two-image mirror. (Note that the
       -i and -m arguments behave differently: -i specifies the total number of stripes, but  -m  specifies  the
       number of images in addition to the first image).
       lvcreate --type raid10 -L 5G -i 2 -m 1 -n mylv vg00

       Create a 1TiB thin LV mythin, with 256GiB thinpool tpool0 in vg00.
       lvcreate --T --size 256G --name mythin vg00/tpool0

       Create  a  1TiB  thin LV, first creating a new thin pool for it, where the thin pool has 100MiB of space,
       uses 2 stripes, has a 64KiB stripe size, and 256KiB chunk size.
       lvcreate --type thin --name mylv --thinpool mypool
              -V 1t -L 100m -i 2 -I 64 -c 256 vg00

       Create a thin snapshot of a thin LV (the size option must not be used, otherwise a copy-on-write snapshot
       would be created).
       lvcreate --snapshot --name mysnap vg00/thinvol

       Create  a  thin snapshot of the read-only inactive LV named "origin" which becomes an external origin for
       the thin snapshot LV.
       lvcreate --snapshot --name mysnap --thinpool mypool vg00/origin

       Create a cache pool from a fast physical device. The cache pool can then be used to cache an LV.
       lvcreate --type cache-pool -L 1G -n my_cpool vg00 /dev/fast1

       Create a cache LV, first creating a new origin LV on a slow  physical  device,  then  combining  the  new
       origin LV with an existing cache pool.
       lvcreate --type cache --cachepool my_cpool
              -L 100G -n mylv vg00 /dev/slow1

       Create a VDO LV vdo0 with VDOPoolLV size of 10GiB and name vpool1.
       lvcreate --vdo --size 10G --name vdo0 vg00/vpool1
