Does it apply for the blocks holding meta data,
e.g. will pvremove issue discard requests for the PV meta data ?
The discards are only issued for the physical extents that were used in
a volume's data area. PV metadata isn't discarded, and really there
would be little benefit to doing so.
The metadata is written over so that the PV is no longer recognized.
I think that issuing a discard for the metadata would actually be
incorrect.
