Second, ZFS has lots of on-disk checking with copy-on-write semantics.
Zope's ZODB uses copy-on-write also. The Data.fs file which contains the database is ever-expanding. This removes lots of failure modes. You do have to repack the database every so often to sort of garbage collect the stuff which is no longer referenced. Does ZFS do something like this also?
