Hi, I have about 200 VMs with a common RBD volume as their root filesystem and a number of additional filesystems on Ceph.
All of them have stopped responding. One of the OSDs in my cluster is marked full. I tried stopping that OSD to force things to rebalance or at least go to degraded mode, but nothing is responding still. I'm not exactly sure what to do or how to investigate. Suggestions?
