NAME
lvrename - rename a logical volume SYNOPSIS
lvrename [-A|--autobackup {y|n}] [-d|--debug] [-h|--help] [-v|--verbose] [--version] {OldLogicalVolumePath NewLogicalVolume{Path|Name} | VolumeGroupName OldLogicalVolumeName NewLogicalVolumeName} DESCRIPTION
lvrename renames an existing logical volume from OldLogicalVolume{Name|Path} to NewLogicalVolume{Name|Path}. 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 progress messages. EXAMPLE
To rename lvold in volume group vg02 to lvnew: lvrename /dev/vg02/lvold /dev/vg02/lvnew An alternate syntax to rename this logical volume is lvrename vg02 lvold lvnew DIAGNOSTICS
lvrename returns an exit code of 0 for success or > 0 for error: 1 invalid logical volume name 2 error checking existence of volume group 3 volume group inactive 4 new logical volume special file already exists 5 old logical volume doesn't exist 6 volume group names are different 7 new logical volume already exist 9 error reading volume group 10 error getting index of old logical volume 11 error renaming logical volume in kernel 12 error creating new logical volume in kernel 13 error writing VGDA to physical volume(s) 14 error creating device special for new logical volume 15 invalid volume group name 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 determins 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 steps are you able to backup with vgcfgrestore(8) from the changes you make to your volume groups. LVM_VG_NAME The default Volume Group Name to use. Setting this variable enables you to enter just the Logical Volume Name rather than its com- plete path. SEE ALSO

NAME
vgchange - change attributes of a volume group SYNOPSIS
vgchange [-A|--autobackup {y|n}] [-a|--available {y|n}] [-d|--debug] [-h|--help] [-l|--logicalvolume MaxLogicalVolumes] [-v|--verbose] [--version] [-x|--allocation {y|n}] [VolumeGroupName...] DESCRIPTION
vgchange allows you to change the attributes of one or more volume groups. Its main purpose is to activate and deactivate VolumeGroupName, or all volume groups if none is specified. Only active volume groups are subject to changes and allow access to their logical volumes. During volume group activation, if vgchange recognizes snapshot logical volumes which were dropped because they ran out of space, it dis- plays a message informing the administrator that such snapshots should be removed (see lvremove(8)). OPTIONS -A, --autobackup{y|n} Controls automatic backup of metadata after the change. See vgcfgbackup (8). Default is yes. -a, --available{y|n} Controls the availability of the volume group for input/output. In other words: makes a volume group known/unknown to the kernel. -d, --debug Enables additional debugging output (if compiled with DEBUG). -h, --help Print a usage message on standard output and exit successfully. -l, --logicalvolume MaxLogicalVolumes Changes the maximum logical volume number of an existing inactive volume group. -v, --verbose Displays verbose runtime information about vgchange's activities. --version Displays tool and IOP version and exit successfully. -x, --allocation{y|n} Enables or disables the extension/reduction of this volume group with/by physical volumes. EXAMPLES
To activate all known volume groups in the system: vgchange -a y To change the maximum number of logical volumes of inactive volume group vg00 to 128. vgchange -l 128 /dev/vg00 DIAGNOSTICS
vgchange returns an exit code of 0 for success and > 0 for error: 1 error writing VGDA to physical volume(s) 2 error changing extensibility of volume group 3 error doing backup of VGDA 4 extension of MaxLogicalVolume would cause overlapped physical extents 5 error backup of volume group metadata 6 error copying volume group metadata to work file 7 error creating volume group directory and special files 8 error removing volume group directory and special files 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 If volume groups can't be activated, run vgscan(8) and retry. 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
