Description

Hot dir would be replicated to other active MDSes, but if replica MDS restarted, auth MDS won't replicate this dir again even if it is still hot. This is because dir's dir_rep is set and dir is still hot, dir's dir_rep won't be unset.

So try to compare the active MDSes with dir's replica set, and replicat it to the MDS whom hasn't contain this dir's replica.
