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 hard-
ware snapshot of existing PVs.
A duplicated VG cannot used until it is made to coexist with the origi-
nal 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 ]
[ 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 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 set-
tings. 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 lvm-
lockd(8) for more information.
--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 --ver-
bose. 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 un-
usual 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 de-
tail 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 ex-
tents (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 con-
tent.
Size[UNIT]
Size is an input number that accepts an optional unit. Input
units are always treated as base two values, regardless of capi-
talization, e.g. 'k' and 'K' both refer to 1024. The default
input unit is specified by letter, followed by |UNIT. UNIT rep-
resents 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
An original VG "vg00" has PVs "/dev/sda" and "/dev/sdb". The corre-
sponding 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
