Hello guys, I’m having an issue with Rancher 2.0
Suddenly, the UI is showing that the Control Pane and etcd node is unavailable, and show that “kubelet has disk pressure”.
The server have plenty of free space and i-nodes.
How can I fix this?
Best regards.
“plenty” is relative… the default thresholds are 5-15%: https://kubernetes.io/docs/tasks/administer-cluster/out-of-resource/#hard-eviction-thresholds
By “plenty” I mean arround 70% of free space
Check the disk partition(s) used by Docker and Rancher. Docker tends to leave a lot of junk lying around and can fill up log partitions after a while.
