I rebuilt 12TB partition as XFS.  But after about 11GB
of data moved, the system locked up with "bus error".
After reboot, the system looks fine.  The vendor always
runs diags and burns the systems in, though it could
still be hardware or driver issue.

Is it likely to be the OS/XFS with the large partition,
or would you just send it back for diagnostics again?
Supermicros have been very reliable for us, but between
the Adaptec and 1TB SATAs, and the large partition, I'm
not sure how reliable the current drivers are.

I'd hoped to just have one mount point, but could make
2-3 smaller partitions if that seems to be the likely
issue.

Thanks,
