We implement ignore of an mda at label_read time by checking for the ignore bit, and then skipping the reading of the vgname and other information in the metadata. This will have an effect similar to a PV found with no mdas. Thus, it will look like an orphan in the cache until we scan the rest of the system and find a PV with metadata, and the mda will not be on the vg->fid->metadata_areas list so no read/writes will be done to the metadata area.
