I am really hoping you can help. THANKS in advance. I have inherited a Docker swarm running CEPH but I know very little about it.
Current I have an unhealthy ceph environment that will not mount my data drive.
Its a cluster of 4 vm servers. docker01,docker02, docker03, docker-cloud
CL has the /data that is on a separate drive, currently failing to mount.
how can I recover this without loosing the data?
on server docker-cloud, mount /data returns:
mount error 113 = No route to host
docker ps is healthy on all nodes.
