"How to Resolve Kubernetes Node Disk Pressure?"
Description:
Facing node disk pressure in your Kubernetes cluster? This video dives into advanced troubleshooting techniques to address disk pressure issues. Learn how to identify which nodes are under pressure, understand the root cause, and implement strategies to free up disk space or increase node capacity.

Issue1: Identify Disk Pressure
Description: Disk pressure occurs when a node runs out of disk space. Check node status to identify if it's under disk pressure.
Solution: Use the following command to check node conditions
"kubectl describe node node-name"
"kubectl get nodes -o wide"

Issue2: Free Up Disk Space
Description: Clear unnecessary files and logs to free up disk space.
Solution: SSH into the node and remove old logs and unused files:
ssh user@node-ip
sudo du -sh /var/log
sudo rm -rf /var/log/old_logs

sudo journalctl --vacuum-time=1d
