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 exist‐
       ing 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 ]
           [    --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 infor‐
              mation 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 de‐
              bugging.

       -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 informa‐
              tion.

       --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 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 read‐
              ing 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 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 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  hard‐
       ware  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
