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, -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 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.

       --resync
	      Forces  the  complete  resynchronization of a mirror.  In normal
	      circumstances you should not need this option  because  synchro‐
	      nization	happens	 automatically.	 Data is read from the primary
	      mirror device and copied to the others, so this can take a  con‐
	      siderable	 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 moni‐
	      tored 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/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 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.
