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.  Communicates with the
	      kernel device-mapper driver via libdevmapper to activate (-ay) or deactivate  (-an)
	      the logical volumes.

	      If  clustered  locking  is  enabled, -aey 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 exclu-
	      sively 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 con-
	      tiguous, 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_pol-
	      icy 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|rw
	      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  meta-
	      data  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.

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