This is the second time this happened in a couple of weeks. The MDS locks up and the stand-by can't take over so the Montiors black list them. I try to unblack list them, but they still say this in the logs
mds.0.1184394 waiting for osdmap 234947 (which blacklists prior instance)
Do not *ever* unblacklist an MDS. Restart the daemon.
Looking at a pg dump, it looks like the epoch is passed that.
$ ceph pg map 3.756 osdmap e234953 pg 3.756 (3.756) -> up [113,180,115] acting [113,180,115]
Last time, it seemed to just recover after about an hour all by it's self. Any way to speed this up?
