LOL. There's a "verifyarena" command? Silly me, I just had to
s/checkarenas/verifyarena/!
How do you guys know all these obscure command names (let alone what
they do)? Let me guess... you wrote them? Plan 9 is really looking
like a hacker's OS... for hackers, by hackers (of hacks??).
(fast forward)
Using some device mapper "magic", I was able to make the backed-up arena
appear at the correct location in the arena file. The backed-up copy of
the arena verifies OK. The live copy of the arena is reported to have
an incorrect sum... but that's all it says.
Is there a way to look into an arena a little deeper, to find the
offending data? I'd like to debug this, and try to find the cause of
this corruption, in order to avoid it in the future.
