RedHat 9 (Linux i386) - man page for lvchange (redhat section 8)

       lvchange - change attributes of a logical volume

       lvchange   [-A|--autobackup   {y|n}]   [-a|--available	{y|n}]	 [-C|--contiguous  {y|n}]
       [-d|--debug]  [-h|--help]  [-p|--permission  {r|rw}]   [-r|--readahead	ReadAheadSectors]
       [-v/--verbose] LogicalVolumePath [LogicalVolumePath...]

       lvchange allows you to change the attributes of a logical volume.

       -A, --autobackup y/n
	      Controls	automatic  backup of VG metadata after the change ( see vgcfgbackup(8) ).
	      Default is yes.

       -a, --available y/n
	      Controls the availability of the logical volumes for use.  This is  (among  others)
	      useful for changing the logical volume's name ( see lvrename(8) ) safely.

       -C, --contiguous y/n
	      Tries  to  set or resets 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.

       -d, --debug
	      Enables additional debugging output (if compiled with DEBUG).

       -h, --help
	      Print a usage message on standard output and exit successfully.

       -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.

       -v, --verbose
	      Gives verbose runtime information about lvchange's activities.

       "lvchange -x n /dev/vg00/lvol1" prevents the allocation of any physical extents on logical
       volume lvol1 in volume group vg00.

       lvchange returns an exit code of 0 for success or > 0 for error:

       1  invalid logical volume name
       2  error checking existence of volume group
       3  logical volume cannot be opened
       4  logical volume access permissions cannot be set
       5  logical volume status cannot be set
       6  logical volume allocation policy cannot be set
       7  VGDA for logical volume cannot be written to the physical volumes
       8  error changing read ahead sectors

       95 driver/module not in kernel
       96 invalid I/O protocol version
       97 error locking logical volume manager
       98 invalid lvmtab (run vgscan(8))
       99 invalid command line

	      If this variable is set to "no" then the automatic backup of VG  metadata  is  dis-

	      This  variable  determines  the  backup  history	depth  of kept VGDA copy files in
	      /etc/lvmconf. It can be set to a positive number between 0  and  999.   The  higher
	      this number is, the more changes you can restore using vgcfgrestore(8).

	      The  default  Volume  Group Name to use. Setting this variable enables you to enter
	      just the Logical Volume Name rather than its complete path.
