Hi all,
I have a very small cluster consisting of 1 overloaded OSD node and a couple MON/MGR/MDS nodes. I will be adding new OSD nodes to the cluster and need to move 36 drives from the existing node to a new one. I'm running Luminous 12.2.2 on Ubuntu 16.04 and everything was created with ceph-deploy.
What is the best course of action for moving these drives? I have read some posts that suggest I can simply move the drive and once the new OSD node sees the drive it will update the cluster automatically.
Time isn't a problem and I want to minimize risk so I want to move 1 OSD at a time. I was planning on stopping the OSD, moving it to the new host, and waiting for the OSD to become up and in and the cluster to be healthy. Are there any other steps I need to take? Should I do anything different?
Thanks in advance
