+\fBpvmetadataignore\fP When creating a physical volume using the LVM2
+metadata format, this states whether metadata areas should be ignored.
+The default is "n".  If metadata areas on a physical volume are ignored,
+LVM will not not store metadata in the metadata areas present on newly
+created Physical Volumes.  The option can be overridden on the command
+line with \fB--pvmetadataignore\fP.  Metadata areas cannot be created
+or extended after Logical Volumes have been allocated on the device.
