| 10 | .SH DESCRIPTION | |
| 11 | lvchange allows you to change the attributes of a logical volume. | |
| 12 | .SH OPTIONS | |
| 13 | See \fBlvm\fP for common options. | |
| 14 | .TP | |
| 15 | .I \-A, \-\-autobackup y/n | |
| 16 | Controls automatic backup of VG metadata after the change ( see | |
| 17 | .B vgcfgbackup(8) | |
| 18 | ). Default is yes. | |
| 19 | .TP | |
| 20 | .I \-a, \-\-available y/n | |
| 21 | Controls the availability of the logical volumes for use. | |
| 22 | This is (among others) useful for changing the logical volume's name | |
| 23 | ( see | |
| 24 | .B lvrename(8) | |
| 25 | ) safely. | |
| 26 | .TP | |
| 27 | .I \-C, \-\-contiguous y/n | |
| 28 | Tries to set or resets the contiguous allocation policy for | |
| 29 | logical volumes. It's only possible to change a non-contiguous | |
| 30 | logical volume's allocation policy to contiguous, if all of the | |
| 31 | allocated physical extents are already contiguous. | |
| 32 | .TP | |
| 33 | .I \-p, \-\-permission r/w | |
| 34 | Change access permission to read-only or read/write. | |
| 35 | .TP | |
| 36 | .I \-r, \-\-readahead ReadAheadSectors | |
| 37 | Change read ahead sector count per logical between 2 and 120. | |
| 38 | .SH Examples | |
| 39 | "lvchange -x n /dev/vg00/lvol1" prevents the allocation of any physical | |
| 40 | extents on logical volume lvol1 in volume group vg00. | |
