I have been doing significant research and testing of Ceph as a long-term solution for our Cloud Storage Solution. I hope this is the right forum to ask a few questions. 1. I have a 3 node cluster. the first cluster is running the mon, msd and osd0 daemons. The second node is running the osd1 daemon only. I am able to mount the x.x.x.x:/ /mnt/ceph just fine. I have added a 3 node and am running the osd daemon only. I don't want to add this node to the placement group of the 1st 2 nodes, but rather add a 4th and have the 3rd and 4th in a placement group. This would be helpful for different customers or different applications that may or may not need replication to a second data center. 2. Is there anyway to create sub-directories in the client mount for example, mount -t ceph x.x.x.x:/subdirectory /mnt/ceph I am looking forward to placing ceph into our production network as our backup target.
