Description
If an MDS is already having issues with getting behind on trimming its journal or an oversized cache, restarting it may only create new problems with very slow recovery. In particular, if the MDS gets very behind on trimming its journal with 1M or more segments, replay can take hours or longer.
We already track these warnings in MDSMonitor so do a simple check to help the operator or support folks not shoot themselves in the foot.
