.SH DESCRIPTION
pvchange allows you to change the allocation permissions of one or
more physical volumes.
.SH OPTIONS
See \fBlvm\fP for common options.
.TP
.I \-a, \-\-all
If PhysicalVolumePath is not specified on the command line all
physical volumes are searched for and used.
.TP
.I \-u, \-\-uuid
Generate new random UUID for specified physical volumes.
.TP
.I \-x, \-\-allocatable y|n
Enable or disable allocation of physical extents on this physical volume.
.TP
.I \-\-metadataignore y|n
Ignore or un-ignore metadata areas on this physical volume.  If metadata
areas on a physical volume are ignored, LVM will not not store metadata
in the metadata areas present on this Physical Volume.  Metadata areas
cannot be created or extended after Logical Volumes have been allocated
on the device. If you do not want to store metadata on this device, it
is still wise always to allocate a metadata area in case you need it in
the future and to use this option to instruct LVM2 to ignore it.
(This option is not applicable to the old LVM1 metadata format.)
.SH Example
"pvchange -x n /dev/sdk1" disallows the allocation of physical extents
on this physical volume (possibly because of disk errors, or because it will
be removed after freeing it.
