...plus set the NFS fsid for each export server side so they come back
reproducibly each time...

PS: I endorse what John said (now I've finished laughing), I'd suggest
making sure you've at least got ECC memory though and RAID as those are
the two parts that can go bad.  When we had clusters with disks in
compute nodes those were the most frequent failures, now we run diskless
nodes it's memory DIMMs. :-)

All the best,
Chris
