NAME
vgsplit — Move physical volumes into a new or existing volume group
SYNOPSIS
vgsplit option_args position_args
[ option_args ]
DESCRIPTION
vgsplit moves one or more PVs from a source VG (the first VG arg) to a destination VG (the
second VG arg). The PV(s) to move are named after the source and destination VGs, or an
LV is named, in which case the PVs underlying the LV are moved.
If the destination VG does not exist, a new VG is created (command options can be used to
specify properties of the new VG, also see vgcreate(8)).
LVs cannot be split between VGs; each LV must be entirely on the PVs in the source or
destination VG.
vgsplit can only move complete PVs. (See pvmove(8) for moving part of a PV.)
USAGE
Split a VG by specified PVs.

OPTIONS
--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 overridden 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.
--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.
--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.
-l|--maxlogicalvolumes Number
Sets the maximum number of LVs allowed in a VG.
-p|--maxphysicalvolumes Number
Sets the maximum number of PVs that can belong to the VG. The value 0 removes any
limitation. For large numbers of PVs, also see options --pvmetadatacopies, and
--vgmetadatacopies for improving performance.
-M|--metadatatype lvm2
Specifies the type of on-disk metadata to use. lvm2 (or just 2) is the current,
standard format. lvm1 (or just 1) is no longer used.
-n|--name String
Move only PVs used by the named LV.
--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.
--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'.
-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.
--[vg]metadatacopies all|unmanaged|Number
Number of copies of the VG metadata that are kept. VG metadata is kept in VG
metadata areas on PVs in the VG, i.e. reserved space at the start and/or end of the
PVs. Keeping a copy of the VG metadata on every PV can reduce performance in VGs
containing a large number of PVs. When this number is set to a non-zero value, LVM
will automatically choose PVs on which to store metadata, using the metadataignore
flags on PVs to achieve the specified number. The number can also be replaced with
special string values: unmanaged causes LVM to not automatically manage the PV
metadataignore flags. all causes LVM to first clear the metadataignore flags on
all PVs, and then to become unmanaged.
-y|--yes
Do not prompt for confirmation interactively but always assume the answer yes. Use
with extreme caution. (For automatic no, see -qq.)
VARIABLES
VG Volume Group name. See lvm(8) for valid names.
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.
