+Create a separate embedding area of specified size besides PV's data
+area. The embedding area is an area of reserved space on the PV from
+which LVM2 will not allocate any extents and it's kept untouched for
+use with external tools to embed their own data or metadata. The start
+of the embedding area is always aligned, see also \fB--dataalignment\fP
+and \fB--dataalignmentoffset\fP. The embedding area size may eventually
+end up increased due to the alignment, but it's never less than the
+size that is requested. To see the embedding area start and size of
+an existing Physical Volume use \fBpvs -o +ea_start,ea_size\fP.
