Hi Greg, Thanks for replying -- I didn't bother you personally with this before precisely because I didn't think I had enough information there to diagnose the problem fully.

I guess it wouldn't have hurt to do a 'camcontrol rescan' after plugging the new drive. Disklabel seemed perfectly happy, so it didn't occur to me until much later that I hadn't done that. > > - Rebuilding the drive without unmounting the volume first was > > just asking for trouble? > > There have been reports of this kind of problem, mainly from Vallo > Kallaste, who has also responded.

I've added that to my checklist for next time :-) Please let me know if there's any other logs you'd like to see or anything else I can try. I'm actually planning to set up a very similar array on another identical machine once 4.8 is released, so there's a window for experimentation there, on a non-production machine.
