I made a bug report here: https://tracker.ceph.com/issues/44023 I updated from 14.2.6 yesterday and after the update my MDS daemons would not start. I looked at the logs and seemed to initially have an auth error. Setting the keyring location manually in ceph.conf fixed that, but I now get an error where my MDS daemons try to reconnect replay and rejoin, but then crash. Any suggestions on what I can do to trouble shoot? The big tracker post has some logs attached. Rolling back did not fix things. Thank you. -Michael
