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).
