问题
I have 7 nodes in my es cluster with the same cpu and memory. 5 of them have three 1T disks, the other 2 have only one 1T disk. I find that the shards on my cluster frequently relocate, but the disk usage is very unbalanced, for example as below:
usage: 34% free: 1.94TB total: 2.95TB
usage: 55% free: 1.33TB total: 2.95TB
usage: 57% free: 1.27TB total: 2.93TB
usage: 46% free: 1.60TB total: 2.95TB
usage: 55% free: 1.31TB total: 2.93TB
usage: 90% free: 100.40GB total: 1007.93GB
usage: 85% free: 152.79GB total: 1007.93GB
- Is it because the disk are unbalanced?
- can i solve that by making some config?
Thank you
