Thanx so much for the info :) Actually I got the same problem again this morning, and I'm starting to think that this is not an aac driver problem.
You wrote that the problems started recently, and en-masse. Maybe this particular controller's hardware is dying or otherwise misbehaving (brownian movement destroying transistors on the chips, capacitors drying up, lead recrystallizing and oxydizing, and all that sort of hardware destruction)?
A last note: I noticed that the kernel update I did in august (to solve a CIFS problem), leaved my zpools needing an update. I never did this zpool update. Do you think this may cause problems like this? I never did the update, beacuse I don't know: - how long it will take - if the pool remains operative during upgrade - what are the risks - how much it will affect storage responsiveness during upgrade
I think the update would mark your zpool version as infinite (5000) and allow using the "zfs feature flags" and those features which come with them. This would make your pool incompatible with other distros like Sol11 or those stuck at v28. Older zpool upgrades were usually in-place and on-line, basically marking your pool as ready to accept and use new data structures upon newer incoming writes. Another procedure is a "zfs upgrade" which may change on-disk structures, but those did not happen since... a while ago.
