Kubernetes Disk Pressure: Common Causes & How to Fix Them

Kubernetes node disk pressure occurs when a node runs out of available storage space, causing Kubernetes to evict Pods from the node and potentially leading to application downtime, performance issues, and even node crashes. Common causes of node disk pressure include application logs exhausting local storage, running too many Pods on a single node, misconfigured storage requests, and changes to node storage configurations. To detect and troubleshoot node disk pressure, administrators can run specific commands, analyze Pod disk usage, and examine other disk usage. Resolving node disk pressure typically involves increasing storage capacity, deleting log files or container images, removing non-essential Pods, creating a RAM disk, modifying resource limits, or seeking help from observability tools like groundcover. By monitoring for nodes with low disk space and knowing how to effectively troubleshoot and resolve disk pressure events, administrators can ensure the stability and performance of their Kubernetes clusters.
