       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, -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
              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.

              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.

              Disable udev synchronisation. The  process  will  not  wait  for
              notification  from  udev.   It will continue irrespective of any
              possible udev processing in the background.  You should only use
              this if udev is not running or has rules that ignore the devices
              LVM2 creates.

              Make no attempt to interact with dmeventd  unless  --monitor  is
              specified.   Do not use this if dmeventd is already monitoring a

       -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  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.

              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.
