Doesn't the mkdir play with ufs metadata which, IIRC, needs to be
written _synchronously_ to disk which means that if your disk
subsystem is not fast you will lose on synchronous operations whereas
normal operations are using the buffer cache which _may_ mask a slow
disk subsystem somewhat (that was what it is for ....)

Just suspicious about the change volumes on pipe - to me your backup
did not complete correctly so you should not really expect a complete
backup ;-)
