VGCHANGE(8)VGCHANGE(8)NAMEvgchange - change attributes of a volume group
SYNOPSISvgchange [--addtag Tag] [--alloc AllocationPolicy] [-A|--autobackup
{y|n}] [-a|--available [e|l] {y|n}] [-d|--debug] [--deltag Tag]
[-h|--help] [--ignorelockingfailure] [-l|--logicalvolume MaxLogicalVol‐
umes] [-P|--partial] [-t|--test] [-v|--verbose] [--version]
[-x|--resizeable {y|n}] [VolumeGroupName...]
DESCRIPTIONvgchange allows you to change the attributes of one or more volume
groups. Its main purpose is to activate and deactivate VolumeGroup‐
Name, or all volume groups if none is specified. Only active volume
groups are subject to changes and allow access to their logical vol‐
umes. [Not yet implemented: During volume group activation, if
vgchange recognizes snapshot logical volumes which were dropped because
they ran out of space, it displays a message informing the administra‐
tor that such snapshots should be removed (see lvremove(8)). ]
OPTIONS
See lvm for common options.
-A, --autobackup{y|n}
Controls automatic backup of metadata after the change. See
vgcfgbackup (8). Default is yes.
-a, --available[e|l]{y|n}
Controls the availability of the logical volumes in the volume
group for input/output. In other words, makes the logical vol‐
umes known/unknown to the kernel.
If clustered locking is enabled, add 'e' to activate/deactivate
exclusively on one node or 'l' to activate/deactivate only on
the local node. Logical volumes with single-host snapshots are
always activated exclusively because they can only be used on
one node at once.
-l, --logicalvolume MaxLogicalVolumes
Changes the maximum logical volume number of an existing inac‐
tive volume group.
-x, --resizeable{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
