How did that happen? What went wrong with the storage that lead you to run xfs_repair? I think I see the problem, but I first need to confirm what assert is firing by matching commits. > root@elefant:/home/kraush#<br/> > -------------------------------------------------------------------<br/> > What shall I do to repair the file system (about 16 TB, 88% full,<br/> > backuppc storage medium).</div> You'll probably have to wait for a patch to fix the problem. The sooner I can confirm the assert you hit, the sooner I'll be able to get you that patch.
