Current state of fsck.nilfs2 doesn't give many useful details. But debug
output of fsck.nilfs2 contains detailed info about first superblock,
second superblock and segment summaries of all segments. I think that
this output can give to me more understanding about NILFS2 volume state.
Could you share debug output of fsck.nilfs2 for me?
You can found archive with fsck.nilf2 source code in this place:
(http://dubeyko.com/development/FileSystems/NILFS/nilfs-utils-fsck-v.0.04-under-development.tar.gz).
Please, build fsck.nilfs2 but don't install it. The fsck.nilfs2 on the
initial state of development. Currently, fsck.nilfs2 doesn't make any
writing operations. So, you can execute command in such way:
"fsck.nilfs2 -v debug [device] 2> [output-file]". The output file has
a big size, usually.
I'll see if I can do that tonight.
Okay, this is what was printed to stdout by fsck.nilfs2 with debug
verbosity:
fsck.nilfs2 v.0.04-under-development (nilfs-utils 2.1.4)

And here's the log that was printed to stderr:
