implemented GetFenceClients which connects to the ceph cluster and returns the ceph clusterID and the clientaddress that is used for rados connection. Signed-off-by: Madhu Rajanna <[email protected]>
The address we get from ceph contains the ip in the format of 10.244.0.1:0/2686266785 we need to extract the client IP from this address, we already have a helper to extract it, This makes the helper more generic can be reused by multiple packages in the fence controller.

I'm getting this error when trying to run the E2E. I assume |
The error seems to be coming from go-ceph. can you please specify which exact command is failing. https://docs.ceph.com/en/pacific/rados/api/librados/#c.rados_getaddrs is supported in older version as well. its not something new |
This PR implements a csiaddons RPC calls to return the ceph fsID and the client IP that is used to connect to the ceph cluster from the rbd plugin daemonset pod.
