Power Cycle Problems

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hello,

 

On two separate occasions I have lost power to my Ceph cluster. Both times, I had trouble bringing the cluster back to good health. I am wondering if I need to config something that would solve this problem?

After powering back up the cluster, “ceph health” revealed stale pages, mds cluster degraded, 3/3 OSDs down. I tried to issue “sudo /etc/init.d/ceph -a start” but I got no output from the command and the health status did not change.

I ended up having to re-install the cluster to fix the issue, but as my group wants to use Ceph for VM storage in the future, we need to find a solution.

 

Please note I followed the Storage Cluster Quick Start for installation and did not make any Ceph config changes after.

 

Any help would be appreciated.

 

Thanks,

Dan
