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!
