LVM2 checks its metadata is consistent on disk every time you access
a VG.   LVM1 caches its metadata and has less-stringent checks.

That message means it found an anomaly that it couldn't
fix - the metadata on 3 of your devices formed a consistent VG
after you restored the backup, but the metadata on the 4th device hdf3 
still said it was part of the VG.

Filtering tells LVM2 to ignore hdf3 completely, then
pvremove hdf3 wipes LVM metadata from it.
