NAME
vgextend - add physical volumes to a volume group SYNOPSIS
vgextend [-A|--autobackup{y|n}] [-d|--debug] [-h|--help] [-v|--verbose] VolumeGroupName PhysicalVolumePath [PhysicalVolumePath...] DESCRIPTION
vgextend allows you to add one or more initialized physical volumes ( see pvcreate(8) ) to an existing volume group to extend it in size. OPTIONS -A, --autobackup y/n Controls automatic backup of VG metadata after the change ( see vgcfgbackup(8) ). Default is yes. -d, --debug Enables additional debugging output (if compiled with DEBUG). -h, --help Print a usage message on standard output and exit successfully. -v, --verbose Gives verbose runtime information about lvextend's activities. Examples "vgextend vg00 /dev/sda4 /dev/sdn1" tries to extend the existing volume group "vg00" by the new physical volumes (see pvcreate(8) ) "/dev/sdn1" and /dev/sda4". DIAGNOSTICS
vgextend returns an exit code of 0 for success and > 0 for error: 1 no volume group name on command line 2 volume group name not given as first argument 3 no physical volume(s) on command line 4 invalid volume group name 5 error checking existence of volume group 6 inactive volume group 7 error reading VGDA 8 volume group is set to not extendable 9 maximum physical volume number of volume group exceeded 10 error reading all physical volumes 11 error setting up VGDA 12 error extending VGDA in kernel 13 error writing VGDA to physical volume(s) 95 driver/module not in kernel 96 invalid I/O protocol version 97 error locking logical volume manager 98 invalid lvmtab (run vgscan(8)) 99 invalid command line ENVIRONMENT VARIABLES
LVM_AUTOBACKUP If this variable is set to "no" then the automatic backup of VG metadata is turned off. LVM_VG_MAX_BACKUPS This variable determines the backup history depth of kept VGDA copy files in /etc/lvmconf. It can be set to a positive number between 0 and 999. The higher this number is, the more changes you can restore using vgcfgrestore(8). See also lvm(8), vgcreate(8), vgreduce(8), pvcreate(8) AUTHOR

NAME
vgcfgrestore - restore volume group descriptor area SYNOPSIS
vgcfgrestore [-b|--backup_number VolumeGroupBackupNumber] [-d|--debug] [-f|--file VGConfPath] [-l[l]|--list [--list]] [-h|--help] [-i|--ignore_size] [-n|--name VolumeGroupName] [-o|--oldpath OldPhysicalVolumePath] [-t|--test] [-v|--verbose] [PhysicalVolumePath] DESCRIPTION
vgcfgrestore allows you to restore the volume group descriptor area from backup files in /etc/lvmconf or from VGConfPath to the given Phys- icalVolumePath. The default backup file is /etc/lvmconf/VolumeGroupName.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 selection 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 logical volume information con- tained 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 corre- sponding physical volume path in the backup file. -t, --test Do a test run reading the volume group backup WITHOUT trying to restore it -v, --verbose Give verbose runtime information about vgcfgrestore's activities. --version Output the version number and exit successfully. Examples 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 for error: 1 no physical volume on command line 2 invalid physical volume name 3 volume group is active 4 error doing restore to physical volume 5 backup is invalid for this volume group 6 volume group is inconsistent 7 physical volume doesn't belong to volume group backup 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 95 driver/module not in kernel 96 invalid I/O protocol version 97 error locking logical volume manager 98 invalid lvmtab (run vgscan(8)) 99 invalid command line SEE ALSO
