How long did check/repair take?

That looks like each server has a RAID0 of two 22+2 RAID6s (or
perhaps two 20+2 RAID6 given the total size, but perhaps the
filesystem size is 39TiB, not 39TB).

That is a truly STUNNING configuration. :-)

I wonder what the 'su'/'sw' parameters for that filesystem look
like, they could be AMAZING too. :-)
