Hi, I recently upgraded Ubuntu from 18.04 to 20.04, and built and installed
s3ql 3.7.0 (replacing an install of 2.21). All dependencies are at the
correct versions according to the docs, and the tests ran successfully. I
upgraded my Amazon S3 filesystem successfully. Unfortunately though it
looks like there was a problem mounting it, and now it seems to be stuck in
a crashed state. What can I do to recover this situation?
~# fsck.s3ql s3://XXX
ERROR: Can not check mounted file system.
~# umount.s3ql /tmp/XXX
ERROR: File system appears to have crashed.
