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.
[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 administrator 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 volumes 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 inactive
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
