VGSPLIT(8) System Manager's Manual VGSPLIT(8)
vgsplit — Move physical volumes into a new or existing volume group
vgsplit option_args position_args [ option_args ]
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.)
Split a VG by specified PVs. vgsplit VG VG PV ... [ COMMON_OPTIONS ] Split a VG by PVs in a specified LV. vgsplit -n|--name LV VG VG [ COMMON_OPTIONS ] Common options for command: [ -A|--autobackup y|n ] [ -l|--maxlogicalvolumes Number ] [ -p|--maxphysicalvolumes Number ] [ -M|--metadatatype lvm2 ] [ --alloc contiguous|cling|cling_by_tags|normal|anywhere| inherit ] [ --poolmetadataspare y|n ] [ --[vg]metadatacopies all|unmanaged|Number ] Common options for lvm: [ -d|--debug ] [ -h|--help ] [ -q|--quiet ] [ -t|--test ] [ -v|--verbose ] [ -y|--yes ] [ --commandprofile String ] [ --config String ] [ --devices PV ] [ --devicesfile String ] [ --driverloaded y|n ] [ --journal String ] [ --lockopt String ] [ --longhelp ] [ --nohints ] [ --nolocking ] [ --profile String ] [ --version ]
--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 par‐ allel stripes on the same PV. inherit applies the VG pol‐ icy to an LV. contiguous requires new PEs be placed adja‐ cent 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 per‐ formance, e.g. by placing two stripes on the same PV. Op‐ tional positional PV args on the command line can also be used to limit which PVs the command will use for alloca‐ tion. 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 Devices that the command can use. This option can be re‐ peated 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) de‐ vices/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 informa‐ tion 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 --vgmetadat‐ acopies 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. --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, de‐ pending 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 nev‐ ertheless returning success to the calling function. This may lead to unusual error messages in multi-stage opera‐ tions if a tool relies on reading back metadata it be‐ lieves 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 automati‐ cally choose PVs on which to store metadata, using the metadataignore flags on PVs to achieve the specified num‐ ber. 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 be‐ come unmanaged. -y|--yes Do not prompt for confirmation interactively but always assume the answer yes. Use with extreme caution. (For au‐ tomatic no, see -qq.)
VG Volume Group name. See lvm(8) for valid names. PV Physical Volume name, a device path under /dev. For com‐ mands managing physical extents, a PV positional arg gen‐ erally 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, regard‐ less of capitalization, e.g. 'k' and 'K' both refer to 1024. The default input unit is specified by letter, fol‐ lowed 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 con‐ trol --units, where capital letters mean multiple of 1000.)
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.
