I don't read german(?) but that looks like many AG header block
have been overwritten with zeros (0 magic number, 0 sequence #, 0
length, etc) and so even if we can repair the filesystem, I'd
suggest that you need to verify that the data in every file in the
filesystem is correct.
Is that as far as xfs_repair got? If so, it would have appeared to
crash. Can you run the lastest version inside gdb to get a stack
trace when it dies? Or, alternatively, provide a metadump for one of
us to look at more closely?
yes, this is as far xfs_repair got it.
what is ment 'run latest version in gdb?' gnudebugger? how do i do that?
console example needed.
and how do i do the metadump?
thank you
marko
Cheers,
Dave.
