Hello, This is my first real issue since running Ceph for several months. Here's the situation: I've been running an Emperor cluster for several months. All was good. I decided to upgrade since I'm running Ubuntu 13.10 and 0.72.2. I decided to first upgrade Ceph to 0.80.4, which was the last version in the apt repository for 13.10. I upgrade the MON's, then the OSD servers to 0.80.4; all went as expected with no issues. The last thing I did was upgrade the MDS using the same process, but now the MDS won't start. I've tried to manually start the MDS with debugging on, and I have attached the file. It complains that it's looking for "mds.0.20 need osdmap epoch 3602, have 3601". Anyway, I'd don't really use CephFS or RGW, so I don't need the MDS, but I'd like to have it. Can someone tell me how to fix it, or delete it, so I can start over when I do need it? Right now my cluster is HEALTH_WARN because of it. Thanks! Brad -------------- next part -------------- A non-text attachment was scrubbed...
