    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
                  Start  or  stop monitoring a mirrored or snapshot logical volume
                  with 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.
    
                  selects an appropriate set of options. Currently this is equiva-
                  lent  to  using    --ignorelockingfailure,   --ignoremonitoring,
                  --poll n and setting LVM_SUPPRESS_LOCKING_FAILURE_MESSAGES envi-
                  ronment variable.
    
           --noudevsync
                  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.
    
           --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  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.
