drive that was pulled from the pool a long time ago (to flash drive the drive)
- The data on it is useless. exporting/importing would cause either a) errors,

Indeed autoreplace was set to yes for the pools. So I disabled the autoreplace.

permutations again, for current kit.
Build 125 added something I was very eager for earlier, sata
port-multiplier support.Since then, I've seen very little, if
AIUI, this works as designed.
I think the best practice will be to add the L2ARC to syspool (nee rpool).
However, for current NexentaStor releases, you cannot add cache devices
to syspool.
