Hello,
Have recently upgraded a cluster to Luminous (Running Proxmox), at the same time I have upgraded the Compute Cluster to 5.x meaning we now run the latest kernel version (Linux
4.10.15-1) Looking to do the following :
ceph osd set-require-min-compat-client luminous
Below is the output of ceph features, the 4 number next to the last row of luminous is as expected for the 4 Compute nodes, are the other 4 spread across hammer
& jewel log's of when the node's last connected before they was upgraded to Proxmox 5.0, am I safe to run the above command? No other RBD resources are connected to this cluster.
"client": {
"group": {
"features": "0x106b84a842a42",
"release": "hammer",
"num": 1
},
"group": {
"features": "0x40106b84a842a52",
"release": "jewel",
"num": 3
},
"group": {
"features": "0x1ffddff8eea4fffb",
"release": "luminous",
"num": 4
}
