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
