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.
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.
"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
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 complete path.
