Hello, We have two separate networks in our Ceph cluster design: 10.197.5.0/24 - The "front end" network, "skinny pipe", all 1Gbe, intended to be a management or control plane network 10.174.1.0/24 - The "back end" network, "fat pipe", all OSD nodes use 2x bonded 10Gbe, intended to be the data network So we want all of the OSD traffic to go over the "back end", and the MON traffic to go over the "front end". We thought the following would do that: public network = 10.197.5.0/24 # skinny pipe, mgmt & MON traffic cluster network = 10.174.1.0/24 # fat pipe, OSD traffic But that doesn't seem to be the case -- iftop and netstat show that little/no OSD communication is happening over the 10.174.1 network and it's all happening over the 10.197.5 network. What configuration should we be running to enforce the networks per our design? Thanks!
