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] [-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.
DIAGNOSTICS
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
ENVIRONMENT VARIABLES
LVM_AUTOBACKUP If this variable is set to "no" then the automatic backup of VG metadata is disabled. LVM_VG_MAX_BACKUPS 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). LVM_VG_NAME The default Volume Group Name to use. Setting this variable enables you to enter just the Logical Volume Name rather than its com- plete path. See also lvm(8), lvcreate(8)
