NAME
lvchange - change attributes of a logical volumeSYNOPSIS
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...]DESCRIPTION
lvchange allows you to change the attributes of a logical volume.OPTIONS
- -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 contiguous, 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.
Examples
"lvchange -x n /dev/vg00/lvol1" prevents the allocation of any physical extents on logical volume lvol1 in volume group vg00.Important: Use the man command (% man) to see how a command is used on your particular computer.
