Hm. SMART seems fine (see below for ada2 & ada8), but looks fine. I did
look at camcontrol, don't see anything obvious but strange that ada2 & ada8
have the pass first, than the name. I do wonder if perhaps it's the SATA
controller that might be going bad. Can't figure out if both drivers are on
the same controller or not without cracking open the case. Unless you know
some other command that I don't know about :) If it was just 1 disk the
mirror wouldn't go offline if 1 of them had errors, right? It'd just be
marked as degraded but still functional, right? This the entire mirror
drops offline entirely.
