Re: rocksdb corruption with 16.2.6

I was doing a rolling upgrade from 14.2.x -> 15.2.x (wait a week) -> 16.2.5.  It was the last jump that had the hiccup. I'm doing the 16.2.5 -> .6 upgrade as I type this.  So far, so good.

For clarity, was this on upgrading to 16.2.6 from 16.2.5? Or upgrading
from some other release?

I got the exact same error on one of my OSDs when upgrading to 16.  I
used it as an exercise on trying to fix a corrupt rocksdb. A spent a few
days of poking with no success.  I got mostly tool crashes like you are
seeing with no forward progress.

I eventually just gave up, purged the OSD, did a smart long test on the
drive to be sure and then threw it back in the mix.  Been HEALTH OK for
a week now after it finished refilling the drive.
