Hi, In a little project of mine I plan to start ceph storage with a small setup and to be able to scale it up later. Perhaps someone can give me any advice if the following (two nodes with OSDs, third node with Monitor only):
- 2 Nodes (enough RAM + CPU), 6*3TB Harddisk for OSDs -> 9TB usable space in case of 3* redundancy, 1 Monitor on each of the nodes - 1 extra node that has no OSDs but runs a third monitor. - 10GBit Ethernet as storage backbone Later I may add more nodes + OSDs to expand the cluster in case more storage / performance is needed. Would this work / be stable? Or do I need to spread my OSDs to 3 ceph nodes (e.g. in order to achive quorum). In case one of the two OSD nodes fail, would the storage still be accessible? The setup should be used for RBD/QEMU only, no cephfs or the like. Any hints are appreciated!
