BTW, I occasionally wonder about the reason for log corruptions.
If we have an "evaporated" write cache that would stop a write from
going but it wouldn't do a partial sector (< 512 byte) write, would it?
I have presumed that sector writes complete or not and that is what
the log code is based on.

OOI, Jay, how did it fail to mount - what was the log msg?
I presume you couldn't mount such that even the log couldn't be
replayed? Did it fail during replay?
