I am using XFS on an HPC cluster, one single partition of 14 TB, with no 
problem so far.

See this news on Phoronix. XFS is becoming cleaner and leaner. I am 
happy to use ext4 instead of ext3 on usual partitions, but XFS on big 
partitions seems to me still a good choice. Let's see what happens in 
the future.
