LVCHANGE(8)

NAME
lvchange - change attributes of a logical volume

SYNOPSIS
lvchange [-A/--autobackup y/n] [-a/--available y/n] [-C/--contiguous y/n] [-d/--debug] [-h/-?/--help] [--ignorelockingfailure] [-M/--persistent y/n] [--minor minor] [-P/--partial y/n] [-p/--permission r/w] [-r/--readahead ReadAheadSectors] [-t/--test] [-v/--verbose] LogicalVolumePath [LogicalVolumePath...]

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

OPTIONS
See lvm for common options.

-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 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.

--minor minor
    Set the minor number.

-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
    Change read ahead sector count per logical between 2 and 120. Not used by device-mapper.

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