vgcfgrestore



SYNOPSIS

       vgcfgrestore  [-b|--backup_number VolumeGroupBackupNumber]
       [-d|--debug]    [-f|--file    VGConfPath]    [-l[l]|--list
       [--list]]  [-h|--help]  [-i|--ignore_size] [-n|--name Vol­
       umeGroupName]     [-o|--oldpath     OldPhysicalVolumePath]
       [-t|--test] [-v|--verbose] [PhysicalVolumePath]


DESCRIPTION

       vgcfgrestore  restores  the  volume  group descriptor area
       from backup files in /etc/lvmconf or  from  VGConfPath  to
       the  given  initialized  (see  pvcreate(8)  ) PhysicalVol­
       umePath.  The default  backup  file  is  /etc/lvmconf/Vol­
       umeGroupName.conf.   This  command  DOES  NOT restore data
       contained in logical volume(s), only the LVM configuration
       metadata!

   OPTIONS
       -b, --backup_numberVolumeGroupBackupNumber
              Restore  from  the  specified  backup  number.  Use
              together with option -n which gives the name of the
              volume group. See examples below.

       -d, --debug
              Enables  additional  debugging  output (if compiled
              with DEBUG).

       -f, --file VGConfPath
              Restore from the specified path. Useful for  selec­
              tion  of  specific backups in the backup history or
              for copies of VGDA backups.

       -i, --ignore_size
              Restore though the  size  of  the  physical  volume
              doesn't match the one in the backup.

       -l, --list
              Display  volume  group information contained in the
              backup file.  If given twice, the physical and log­
              ical  volume  information  contained  in the backup
              file is also shown.

       -h, --help
              Print a usage message on standard output  and  exit
              successfully.

       -n, --name VolumeGroupName
              Do a restore for this volume group name.

       -o, --oldpath OldPhysicalVolumePath
              If  the  path  to  the  physical volume has changed
              between backup time and restore time,  this  option
              enables  you  to  choose the corresponding physical

       To display information like with "vgdisplay  vg00"  stored
       in the backup file /etc/lvmconf/vg00.conf:

            vgcfgrestore -n vg00 -l

       To  restore  the  VGDA of vg00 from the alternative backup
       file /tmp/vg00-old to physical volume /dev/sdn1:

            vgcfgrestore -f /tmp/vg00-old -n vg00 /dev/sdn1

       To restore the VGDA of vg00 from the alternative backup file
       /etc/lvmconf/vg00.conf.5.old
       to physical volume
       /dev/sda5 :

            vgcfgrestore -n vg00 -b 5 /dev/sda5


DIAGNOSTICS

       vgcfgrestore returns an exit code of 0 for success and > 0

       8  error reading physical volume
       9  error getting size of physical volume
       10 error writing VGDA to physical volume(s)
       11 error removing special files of volume group
       12 error setting volume group into lvmtab
       13 error doing backup
