For sure we DO have users split up into several 5 TB-partitions. This
helps a little, but not a lot. And it creates some extra work and some
extra sources of errors: You'll need Symlinks on the "real" fs or a
user-dependend storage path in LDAP.

But anyway, those partitions are tooo big for short filesystem checks
(or if you make them smaller, you'd have too many).

And, anyway: As I explained I'm interested in zero-downtime-checks,
which wouldn't work just with several partitions.
