With these giant numbers of snapshots I see some other problems: If there should coexist multiple snapshots in the same partition belonging to the same volume group the present design of the linktable of the NAMEI-fileserver will break because it allows only a limited number of versions (5) and a limited value for the link count (7) per version of a vnode number's data.
Also if the volume id should become 64 bit certainly the NAMEI mapping algorithm of volume ids to directory trees would have to change. This change would not only affect the fileserver, volserver and salvager, but also rxosd. Hartmut Matt W.
