       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

              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.

       --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.

              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.
