That one booted properly, so I don't think that was the problem. The dm-cache device still needs further investigation, but I'm going to wait for all RAID arrays to re-sync before further testing. Going through the log again, I'm looking at this line: Dec 4 21:17:34 ascension lvm: WARNING: Device mismatch detected for VolGroup/lv_root which is accessing /dev/md127 instead of /dev/sda3. Since it says "is accessing /dev/md127", I think the kernel activated the LVs properly, in which case there shouldn't be any corruption risk. I still can't reason why the lvm tools were scanning the component volumes to begin with.
