-
lvchange allows you to change the attributes of a logical volume
including making them known to the kernel ready for use.
-
See lvm for common options.
- -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.
-
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.
- -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.
- --resync
-
Forces the complete resynchronization of a mirror. In normal
circumstances you should not need this option because synchronization
happens automatically. Data is read from the primary mirror device
and copied to the others, so this can take a considerable amount of
time - and during this time you are without a complete redundant copy
of your data.
- --minor minor
-
Set the minor number.
- --monitor y/n
-
Controls whether or not a mirrored logical volume is monitored by
dmeventd, if it is installed.
If a device used by a monitored mirror reports an I/O error,
the failure is handled according to
mirror_image_fault_policy and mirror_log_fault_policy
set in lvm.conf.
- --ignoremonitoring
-
Make no attempt to interact with dmeventd unless --monitor
is specified.
Do not use this if dmeventd is already monitoring a device.
- -M, --persistent y/n
-
Set to y to make the minor number specified persistent.
- -p, --permission r/w
-
Change access permission to read-only or read/write.
- -r, --readahead ReadAheadSectors|auto|none
-
Set read ahead sector count of this logical volume.
For volume groups with metadata in lvm1 format, this must
be a value between 2 and 120 sectors.
The default value is "auto" which allows the kernel to choose
a suitable value automatically.
"None" is equivalent to specifying zero.
- --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.
-
"lvchange -pr vg00/lvol1" changes the permission on
volume lvol1 in volume group vg00 to be read-only.
