ceph-hammer - problem adding / removing monitors

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

 



Hi everyone.  We’re running ceph-hammer, and I was trying to rename our monitor servers.  I tried following the procedure for removing a monitor, and adding a monitor.  Removing seems to have work ok, as now I have 2 monitors up.  

When I try to add the 3rd monitor, and the ceph-deploy completes,  I see this error in the logs: 

cephx: verify_reply couldn't decrypt with error: error decoding block for decryption


Now I have a cluster with only 2 monitors.  My last resort was to stop all my monitors and manually inject a new monmap.  Hopefully this isn’t necessary.


Can anyone help?  Thanks!
