Re: Online verification of checksums

Hallo Michael,

> Yeah, new rebased version attached.

Patch v8 applies cleanly, compiles, global & local make check are ok.

A few comments:

About added tests: the node is left running at the end of the script, 
which is not very clean. I'd suggest to either move the added checks 
before stopping, or to stop again at the end of the script, depending on 
the intention.

I'm wondering (possibly again) about the existing early exit if one block 
cannot be read on retry: the command should count this as a kind of bad 
block, proceed on checking other files, and obviously fail in the end, but 
having checked everything else and generated a report. I do not think that 
this condition warrants a full stop. ISTM that under rare race conditions 
(eg, an unlucky concurrent "drop database" or "drop table") this could 
happen when online, although I could not trigger one despite heavy 
testing, so I'm possibly mistaken.
