Thank you very much for looking into this. I'm glad to hear that it is a
problem that has been resolved upstream. Everything important on the
disk is backed up elsewhere, so reformatting is no big deal.
Thanks again,
Ray

Hi,
Very unfortunately, such the *unreachable NIDs* error was resolved by
the recent patches fixing several recovery routines. So it needs to use
the latest F2FS source urgently.
Even the worse thing is that we don't have fsck.f2fs fixing the file
system consistency, so that it needs to reformat the failed disk.
Sorry for that.
But, I strongly convince that most of recovery bugs have been fixed so
far. Hence you can believe that the current F2FS is very much stable
than ever before.
Thanks,
