Ubuntu Manpage: vgimportclone - Import a VG from cloned PVs

Provided by: lvm2_2.02.176-4.1ubuntu3.18.04.3_amd64

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 ]
           [ 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 ]
           [    --longhelp ]
           [    --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 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).

--longhelp
Display long help text.

--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:
              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 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
