       [-d/--debug]  [--deltag  Tag]  [-h/-?/--help]  [--ignorelockingfailure]
       [-M/--persistent y/n] [--minor minor] [-P/--partial y/n]  [-p/--permis-

       [-v/--verbose] LogicalVolumePath [LogicalVolumePath...]


DESCRIPTION

       lvchange allows you to  change  the  attributes  of  a  logical  volume
       including making them known to the kernel ready for use.


OPTIONS

       See lvm for common options.

       -a, --available y/n/ey/en/ly/ln
              Controls  the availability of the logical volumes for use.  Com-
              municates 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 logi-
              cal volumes. It’s only possible to change a non-contiguous logi-
              cal  volume’s  allocation  policy  to  contiguous, if all of the
              allocated physical extents are already contiguous.

       --minor minor
              Set the minor number.

       -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
              Change read ahead sector count per logical between  2  and  120.
              For compatability with LVM1 only. Ignored by LVM2.

       --refresh
              If  the  logical volume is active, reload its metadata.  This is
              not necessary in normal operation, but may be  useful  if  some-
              thing  has  gone  wrong  or  if you’re doing clustering manually
              without a clustered lock manager.


Examples

       "lvchange -pr vg00/lvol1" changes the permission  on  volume  lvol1  in
       volume group vg00 to be read-only.
