ZFS ready for prime time ?



I'm looking to set up a home directory server for a population of
~50,000 registered users, ~20,000 active, with about 1TB of storage. The
machine should last something like 3-5 years. The future is clearly ZFS,
quotas being done by having a filesystem per person with quotas being
implemented by putting a limit on the space per filesystem. It's all a
bit new for my comfort zone, though, and I was wondering if anyone out
there was doing this. Issues I see are NFS exports: I've seen reports
about bad things happening due to the commit to disk semantics, and
backups: we use Legato Networker, and whilst it backs up one or two ZFS
filesystems without issue (once you've set mountpoint=legacy and put the
filesystems in vfstab) I can't see it coping with 50,000 filesystems on
any reasonable basis.

Your thoughts would be very much appreciated, I will summarize.

Cheers,

Rob
