I'm running fsck_hfs on a very large volume. Unfortunately, there's an issue it appears to be unable to fix -- it reports it, loops back to start with Rechecking..., and reports it again, ad infinitum.

** Checking catalog hierarchy.
   Invalid volume directory count
   (It should be 513997 instead of 513998)
   Incorrect folder count in a directory (id = 27444570)
   (It should be 1 instead of 0)

I've tried adding the -r ("rebuild catalog btree") flag to fsck, but the issue still recurs.

The volume is probably locked, so you should retry what you are doing after booting into either the Recovery HD parition (Command-R while booting) or with a OS X install CD.

  • Checking the mount table, the volume is certainly not mounted anywhere (not even read-only). – Charles Duffy Sep 20 '12 at 20:24
