If you suspend/dtr a mirror, clear region requests are not flushed to disk. This means that the next time a cluster mirror is started, those regions will be incorrectly assumed to be not in-sync. The culprit is in rh_update_states: if (!list_empty(&recovered)) rh->log->type->flush(rh->log); The conditional should be removed. Note that this does not cause extra disk activity, since the (disk) log checks for lc->touched.
