Again, thank you very much Ken. I'm planning to stress test this on 846 case
filled with 12 (yet) WD RE4 disks organized as raidz2, and will post the
results.
Any hints to particularly I/O stressing patterns? Out of my mind, I'm planning
multiple parallel -j'ed builds, parallel tars, *SQL benchmarks -- what else
could you suppose?
benchmarks/iozone is nice, and you can get nifty graphs out of it. It
walks through various block sizes and is very long running. It can
probably tickle lots of stuff. The results are also pretty informative -
you can see very clearly in the graphs whatever your weak spots are.
