Subject: Unmountable fs. No root for superblock generation
Date: Wed, 18 Oct 2017 10:18:48 -0400 [thread overview]
Message-ID: <4b86aa36-8a9d-5af6-06a9-351db3015107@gmail.com> (raw)
I am unable to mount one my my filesystems. The superblock thinks the
latest generation is 2220927 but I can't seem to find a root with that
number. I can find 2220926 and 2220928 but not 2220927. Is there
anything that I can do to recover this FS?

Well block 101489031790592(gen: 2220928 level: 2) seems good, but
generation/level doesn't match, want gen: 2220927 level: 2
