unrecognized tag byte 0 in stream; skipping

[iwen65]

eve4barc is running since 2 years without any problem. Out of the sudden, I can not recover a backup (keep-mode) at all. None of the diff parts can be used.

I get a flood of "unrecognized tag byte 0 in stream; skipping" messages

and at the end
7fcae69b4f40 -1 librbd::Operations: New size not compatible with object map

After some further operations (successfull) I get the message "Successfully recovered".

But the image is unusable.
Any ideas whats going wrong?

Hi.
I have no idea. Try to run with the --debug parameter so we have a detailed log

Best regards
