I had 150-300GB each on a few Irix 6.x boxes and ran into issues. I
also tested xfs on 2.4.x linux kernels with ~1TB file systems and had
the same problem -- I ran reiserfs in the end. This was circa 2000-2001
and I have not used xfs since.
The client premise experiences frequent power outages.
I don't think the xfs situation has improved, and would not recommend
using it with unreliable power or hardware. Unless you are exceeding the
limits of a tuned ext3/4, it's best not to move away from ext3/4.
Btw, are you having all 6TB on a single file system? Any file system
corruption can hose the entire volume and take a lot of data with it.
