NAME

       vgimportclone — Import a VG from cloned PVs

SYNOPSIS

       vgimportclone position_args
           [ option_args ]

DESCRIPTION

       vgimportclone imports a VG from duplicated PVs, e.g. created by a hardware snapshot of existing PVs.

       A  duplicated  VG cannot used until it is made to coexist with the original VG. vgimportclone renames the
       VG associated with the specified PVs and changes the associated VG and PV UUIDs.

USAGE

       vgimportclone PV ...
           [ -n|--basevgname VG ]
           [ -i|--import ]
           [    --importdevices ]

           [    --version ]

OPTIONS

       -n|--basevgname String
              By default the snapshot VG will be renamed to the original name plus a  numeric  suffix  to  avoid
              duplicate  naming  (e.g.  'test_vg' would be renamed to 'test_vg1'). This option will override the
              base VG name that is used for all VG renames. If a VG already exists with  the  specified  name  a
              numeric suffix will be added (like the previous example) to make it unique.

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

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

       -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).

       --devices PV
              Restricts  the  devices  that  are visible and accessible to the command.  Devices not listed will
              appear to be missing. This option can be repeated, or accepts a comma separated list  of  devices.
              This overrides the devices file.

       --devicesfile String
              A  file  listing  devices  that  LVM  should use.  The file must exist in /etc/lvm/devices/ and is
              managed with the lvmdevices(8) command.  This overrides the  lvm.conf(5)  devices/devicesfile  and
              devices/use_devicesfile settings.

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

       -h|--help
              Display help text.

       -i|--import
              Import  exported  VGs.  Otherwise  VGs that have been exported will not be changed (nor will their
              associated PVs).

       --importdevices
              Add devices to the devices file.

       --journal String
              Record information in the systemd journal.  This information is in addition to information enabled
              by  the  lvm.conf  log/journal  setting.   command: record information about the command.  output:
              record the default command output.  debug: record full command debugging.

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

       --longhelp
              Display long help text.

       --nohints
              Do not use the hints file to locate devices for PVs. A command may read more devices to  find  PVs
              when  hints  are  not  used.  The command will still perform standard hint file invalidation where
              appropriate.

       --nolocking
              Disable locking. Use with caution, concurrent commands may produce incorrect results.

       --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'.

       -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.

       -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.

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

VARIABLES

       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:  b|B  is
              bytes,  s|S  is  sectors of 512 bytes, k|K is KiB, m|M is MiB, g|G is GiB, t|T is TiB, p|P is PiB,
              e|E is EiB.  (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

       An original VG "vg00" has PVs "/dev/sda" and "/dev/sdb".  The corresponding PVs from a hardware  snapshot
       are  "/dev/sdc"  and  "/dev/sdd".  Rename the VG associated with "/dev/sdc" and "/dev/sdd" from "vg00" to
       "vg00_snap" (and change associated UUIDs).
       vgimportclone --basevgname vg00_snap /dev/sdc /dev/sdd
