4.2.3. Preventing Allocation on a Physical Volume
You can prevent allocation of physical extents on the free space of one or more physical volumes with the
pvchangecommand. This may be necessary if there are disk errors, or if you will be removing the physical volume.
The following command disallows the allocation of physical extents on
pvchange -x n /dev/sdk1
You can also use the
-xyarguments of the
pvchangecommand to allow allocation where it had previously been disallowed.
