Pete, isn't this your case? Afraid not, both machines are running normal "spinning rust" hard drives as the actual storage layer, so there is nothing TRIM capable anywhere. I didnt get much chnace to look at this yesterday, but am looking at the logs again now, and I see these messages right up to the time the machine fell over. That machine had been up for a long time, and it was still logging these messages, so it looks very much as if ZFS did not stop trying to issue the TRIM. -pete.
