Ceph monitor problems

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

 



All,

 

My ceph cluster is failing to respond to calls for health status etc.  It simply hangs at each command and then tells me there is an error connecting to the cluster.   I assume that it is because I tried to add a second monitor which seemed to hang during the “hunting” phase.  I eventually had to kill the tasks which I think resulted in my monmap becoming corrupt.   I have tried to access it from the only remaining working monitor, but have not had much joy with that.

 

I have also tried to follow the docs re removing monitors from unhealthy clusters, but have as yet had no luck with getting the stable monmap extracted....

 

When I run any ceph command from the remaining monitor host I get the following error:

 

2013-10-30 14:19:01.822660 7f16080f2700 -1 monclient(hunting): ERROR: missing keyring, cannot use cephx for authentication

2013-10-30 14:19:01.822743 7f16080f2700  0 librados: client.admin initialization error (2) No such file or directory

Error connecting to cluster: ObjectNotFound

 

It’s the hunting part which implies that something is still stuck from when I tried to add the second monitor.

 

Any ideas on how I can fix the monmap so the remaining monitor can be used again?

 

Thanks.
