Geoff, I've hit this problem several times in the past, with OpenSolaris and then with OpenIndiana.
There are, to my knowledge, no available solutions, it is so by design! If a disk stops responding the pool waits until after it responds again (sometimes pulling it out of its slot and then reinserting the disk causes a reset of the link and it starts working again). I was not able to assess what happens if I set failmode to continue. I think it could be no better since you still cannot write to the pool. This is IMHO the biggest problem of ZFS, in that I cannot instruct it to stop using a failed device if it has some level of redundancy still available. Wait is OK only if an entire vdev stops responding, not if a disk in a vdev with redundancy has problems either fatal or transitory. Best regards. Maurilio. PS. Using server grade disks (those with TLER) makes it possibile to overcome this problem for transitory errors.
