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.
thanks,
-Eric
