18 lvchange allows you to change the attributes of a logical volume
19 including making them known to the kernel ready for use.
20
22 See lvm for common options.
23 -a, --available y/n/ey/en/ly/ln
25 Controls the availability of the logical volumes for use. Com‐
26 municates with the kernel device-mapper driver via libdevmapper
27 to activate (-ay) or deactivate (-an) the logical volumes.
28 If clustered locking is enabled, -ae will activate exclusively
30 on one node and -aly will activate only on the local node. To
31 deactivate only on the local node use -aln. Logical volumes
32 with single-host snapshots are always activated exclusively
33 because they can only be used on one node at once.
34 -C, --contiguous y/n
36 Tries to set or reset the contiguous allocation policy for logi‐
37 cal volumes. It's only possible to change a non-contiguous logi‐
38 cal volume's allocation policy to contiguous, if all of the
39 allocated physical extents are already contiguous.
40 --resync
42 Forces the complete resynchronization of a mirror. In normal
43 circumstances you should not need this option because synchro‐
44 nization happens automatically. Data is read from the primary
45 mirror device and copied to the others, so this can take a con‐
46 siderable amount of time - and during this time you are without
47 a complete redundant copy of your data.
48 --minor minor
50 Set the minor number.
51 --monitor y/n
53 Controls whether or not a mirrored logical volume is monitored
54 by dmeventd, if it is installed. If a device used by a moni‐
55 tored mirror reports an I/O error, the failure is handled
56 according to mirror_image_fault_policy and mirror_log_fault_pol‐
57 icy set in lvm.conf.
58 -M, --persistent y/n
60 Set to y to make the minor number specified persistent.
61 -p, --permission r/w
63 Change access permission to read-only or read/write.
64 -r, --readahead ReadAheadSectors
66 Change read ahead sector count per logical between 2 and 120.
67 For compatability with LVM1 only. Ignored by LVM2.
68 --refresh
70 If the logical volume is active, reload its metadata. This is
71 not necessary in normal operation, but may be useful if some‐
72 thing has gone wrong or if you're doing clustering manually
73 without a clustered lock manager.
74
76 "lvchange -pr vg00/lvol1" changes the permission on volume lvol1 in
77 volume group vg00 to be read-only.
