VGIMPORTCLONE(8) System Manager's Manual VGIMPORTCLONE(8)
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 ex-
isting PVs.
A duplicated VG cannot used until it is made to coexist with the original VG. vgimport-
clone renames the VG associated with the specified PVs and changes the associated VG and
PV UUIDs.
USAGE
vgimportclone PV ...
[ -n|--basevgname VG ]
[ -i|--import ]
[ COMMON_OPTIONS ]
Common options for lvm:
[ -d|--debug ]
[ -h|--help ]
[ -q|--quiet ]
[ -t|--test ]
[ -v|--verbose ]
[ -y|--yes ]
[ --commandprofile String ]
[ --config String ]
[ --driverloaded y|n ]
[ --lockopt String ]
[ --longhelp ]
[ --nolocking ]
[ --profile String ]
[ --version ]
OPTIONS
-n|--basevgname String
By default the snapshot VG will be renamed to the original name plus a numeric suf-
fix 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 al-
ready exists with the specified name a numeric suffix will be added (like the pre-
vious example) to make it unique.
--commandprofile String
The command profile to use for command configuration. See lvm.conf(5) for more in-
formation about profiles.
--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.
-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).
--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).
--lockopt String
Used to pass options for special cases to lvmlockd. See lvmlockd(8) for more in-
formation.
--longhelp
Display long help text.
--nolocking
Disable locking.
--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 dis-
abling all metadata writing but nevertheless returning success to the calling func-
tion. 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 ex-
tents, a PV positional arg generally accepts a suffix indicating a range (or multi-
ple 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 re-
fer 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 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
