Upgraded to 12.10 and 3.5.0-26, the filesystem is still hosed. I'm rerunning a 'balance', but I notice with 'iostat' that disk bandwidth is very poorly utilized (getting a couple of MB/s from each disk, and mostly one at a time). Still, there is now quite a bit of space on all spindles, and it didn't seem to help much.
