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 -p r vg00/lvol1" changes the permission on volume lvol1 in volume group vg00 to be read-only.SEE ALSO
