VGIMPORTCLONE(8)         System Manager's Manual         VGIMPORTCLONE(8)

NAME         top

       vgimportclone — Import a VG from cloned PVs

SYNOPSIS         top

       vgimportclone position_args
           [ option_args ]

DESCRIPTION         top

       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.

OPTIONS         top


       -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(5)
              settings.   The  String  arg  uses  the  same   format   as
              lvm.conf(5),   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).

       --devices PV
              Devices that the  command  can  use.  This  option  can  be
              repeated or accepts a comma separated list of devices. This
              overrides the devices file.

       --devicesfile String
              A  file listing devices that LVM should use.  The file must
              exist  in  /etc/lvm/devices/  and  is  managed   with   the
              lvmdevices(8)  command.   This  overrides  the  lvm.conf(5)
              devices/devicesfile and devices/use_devicesfile settings.

       --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).

       --importdevices
              Add devices to the devices file.

       --journal String
              Record  information   in   the   systemd   journal.    This
              information  is  in  addition to information enabled by the
              lvm.conf log/journal setting.  command: record  information
              about  the  command.   output:  record  the default command
              output.  debug: record full command debugging.

       --lockopt String
              Used to pass options for special cases  to  lvmlockd.   See
              lvmlockd(8) for more information.

       --longhelp
              Display long help text.

       --nohints
              Do  not  use  the  hints  file to locate devices for PVs. A
              command may read more devices to find PVs  when  hints  are
              not used. The command will still perform standard hint file
              invalidation where appropriate.

       --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  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         top

       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: 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         top

       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         top

       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
