Hi, For one of our Ceph clusters, I’m trying to modify the balancer configuration, so it will keep working until it achieves a better distribution. After checking the mailing list, looks like that the key controlling this for upmap is mgr/balancer/upmap_max_deviation but it does not seem to make any difference (even after restarting the active mgr daemon) and I keep
getting the “Error EALREADY: Unable to find further optimization,or distribution is already perfect” message when trying to create a new plan. On the other side, if I download the map and I use the osdmaptool and specify the --upmap-deviation parameter it works as expected. Here is the output of ceph config-key dump: { "mgr/balancer/active": "1", "mgr/balancer/max_misplaced": "0.01", "mgr/balancer/mode": "upmap", "mgr/balancer/upmap_max_deviation": ".002" } Any ideas? Thanks! Xavier Trilla P. |
