.SH DESCRIPTION
|
|
lvchange allows you to change the attributes of a logical volume
|
|
including making them known to the kernel ready for use.
|
|
.SH OPTIONS
|
|
See \fBlvm\fP for common options.
|
|
.TP
|
|
.I \-a, \-\-available y/n/ey/en/ly/ln
|
|
Controls the availability of the logical volumes for use.
|
|
Communicates with the kernel device-mapper driver via
|
|
libdevmapper to activate (-ay) or deactivate (-an) the
|
|
logical volumes.
|
|
.IP
|
|
If clustered locking is enabled, -ae will activate exclusively
|
|
on one node and -aly will activate only on the local node.
|
|
To deactivate only on the local node use -aln.
|
|
Logical volumes with single-host snapshots are always activated
|
|
exclusively because they can only be used on one node at once.
|
|
.TP
|
|
.I \-C, \-\-contiguous y/n
|
|
Tries to set or reset the contiguous allocation policy for
|
|
logical volumes. It's only possible to change a non-contiguous
|
|
logical volume's allocation policy to contiguous, if all of the
|
|
allocated physical extents are already contiguous.
|
|
.TP
|
|
.I \-\-minor minor
|
|
Set the minor number.
|
|
.TP
|
|
.I \-M, \-\-persistent y/n
|
|
Set to y to make the minor number specified persistent.
|
|
.TP
|
|
.I \-p, \-\-permission r/w
|
|
Change access permission to read-only or read/write.
|
|
.TP
|
|
.I \-r, \-\-readahead ReadAheadSectors
|
|
Change read ahead sector count per logical between 2 and 120.
|
|
For compatability with LVM1 only. Ignored by LVM2.
|
|
.TP
|
|
.I \-\-refresh
|
|
If the logical volume is active, reload its metadata.
|
|
This is not necessary in normal operation, but may be useful
|
|
if something has gone wrong or if you're doing clustering
|
|
manually without a clustered lock manager.
|
|
.SH Examples
|
|
"lvchange -pr vg00/lvol1" changes the permission on
|
|
volume lvol1 in volume group vg00 to be read-only.
