lvchange allows you to change the attributes of a logical volume including making them known to the kernel ready for use.
See lvm for common options. -a, --available y|n|ey|en|ly|ln Controls the availability of the logical volumes for use. Com- municates with the kernel device-mapper driver via libdevmapper to activate (-ay) or deactivate (-an) the logical volumes. If clustered locking is enabled, -aey will activate exclusively on one node and -aly will activate only on the local node. To deactivate only on the local node use -aln. Logical volumes with single-host snapshots are always activated exclusively because they can only be used on one node at once. -C, --contiguous y|n Tries to set or reset the contiguous allocation policy for logi- cal volumes. It's only possible to change a non-contiguous logi- cal volume's allocation policy to contiguous, if all of the allocated physical extents are already contiguous. --resync Forces the complete resynchronization of a mirror. In normal circumstances you should not need this option because synchro- nization happens automatically. Data is read from the primary mirror device and copied to the others, so this can take a con- siderable amount of time - and during this time you are without a complete redundant copy of your data. --minor minor Set the minor number. --monitor y|n Controls whether or not a mirrored logical volume is monitored by dmeventd, if it is installed. If a device used by a moni- tored mirror reports an I/O error, the failure is handled according to mirror_image_fault_policy and mirror_log_fault_pol- icy set in lvm.conf. --ignoremonitoring Make no attempt to interact with dmeventd unless --monitor is specified. Do not use this if dmeventd is already monitoring a device. -M, --persistent y|n Set to y to make the minor number specified persistent. -p, --permission r|rw Change access permission to read-only or read/write. -r, --readahead ReadAheadSectors|auto|none Set read ahead sector count of this logical volume. For volume groups with metadata in lvm1 format, this must be a value between 2 and 120 sectors. The default value is "auto" which allows the kernel to choose a suitable value automatically. "None" is equivalent to specifying zero. --refresh If the logical volume is active, reload its metadata. This is not necessary in normal operation, but may be useful if some- thing has gone wrong or if you're doing clustering manually without a clustered lock manager. Examples "lvchange -pr vg00/lvol1" changes the permission on volume lvol1 in volume group vg00 to be read-only.
