Yes we are -  I've used 1.4 TB volumes using Linux fileservers
for about 8 months without problems.  I just started using some
1.95 Tb volumes sitting on Solaris ZFS fileservers  - most of these 
volumes contain lightly used data.

Things are fine for the most part - as you might guess volume moves
take a while - My general rule of thumb is to expect 200 GB per
hour for moves - so a volume with 1 TB of data in it takes 5 hours.

I had an issue with using up and moving large files - I hope to
submit a bug to Sine Nomine later this week regarding this.
