I will run it in a loop this time. I didn't do it last time because of
the error.
This box was running only raidz sets originally. After running into
performance problems we added a bunch of mirrors to try to improve the
iops. The logs are not mirrored right now as we were testing adding
the other two as cache disks to see if that helped. We've also tested
using a ramdisk ZIL to see if that made any difference- it did not.
The performance on this box was excellent until it started to fill up
(somewhere around 70%)- then performance degraded significantly. We
added more disks, and copied the data around to rebalance things. It
seems to have helped somewhat- but it is nothing like when we first
created the array.
