I while ago, I’ve put together some notes on fsck and error types - it’s a PR against the EOS docs:
Questions regarding this seem to pop up from time to time, as in
How to audit and repair storage with fsck and
Fsck : settings, communication between managers and FSTs - #13 by barbet
We had very similar issues, and wrote down what we learned as good as possible.
It would be great to get some comments on this (and have this eventually merged to the main branch).
