This is actually normal.  For some reason that would probably make me
throw up if I knew it, getfattr misreports 0x000000000000000000000000
as 0sAAAAAAAAAAAAAAAA (which would be 0x404040404040404040404040) if
you don't give it the "-e hex" flag.  The value is actually three
four-byte integers, and if they're zero it means there are no pending
operations.  Any *other* value is likely to indicate split brain.
