    Yes, I was trying to think of scenarios and I think you are close,
    that is likely the reason.  The hammer cleanup code is only scanning
    mounted PFSs.  I verified this by umounting my /var/crash (which is
    a PFS) and running hammer cleanup.  It didn't check /var/crash's

    So its not master/slave, it is simply whether the PFS is mounted or
    not that is the problem.

    This is definitely a bug.  hammer cleanup needs to go through all
    the PFSs.  It would be a nice mini-programming-project for someone
    who wants to fix it in the hammer utility.
