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
