My company has hosted MarkLogic on Amazon and we have a cluster with 3 MarkLogic instances. All 3 instances have volume attached of size 2700 GiB. However when I open Monitoring Dashboard and check Disk Space tab, I see data is unevenly distributed.
Instance 1 Forest Data - 1442GB Forest Reserve - 416GB Free Space - 42GB
Instance 2 Forest Data - 1445GB Forest Reserve - 418GB Free Space - 567GB
Instance 3 Forest Data - 1440GB Forest Reserve - 414GB Free Space - 643GB
My Question is why in Instance 1 I am seeing less free space (42 GB)? Data should be evenly distributed. How to mitigate this?
