Hello.I have a 39TB xfs filesystem in a SAN that got corrupted. The reasons for the corruption are unclear. I've been trying to fix it using xfs_repair but the repair operation always hangs at Phase 6 "traversing filesystem ...".
Ok, so strace was stuck? Can you try again with -P? If that fails can you try again with -P -o bhashsize=1024 ? (or so; 1024 is the default, you could double it again if it still hangs) You might also attach gdb and see where it is.If increasing the bhashsize fixes it then I probably know what the bug is (though not yet the solution...)
If you want to provide an xfs_metadump image of it from before you repair it, I could test any eventual fix against that.
