I don't have much new information, other than that I tested booting a
similar system with an intentionally degraded RAID volume. 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.
