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.
