If a node crashes, the underlying filesystem containing CRI directories may corrupt. You cannot run fsck on a mounted device. The here is to unmount the CRI storage partition (often /var/lib/containerd ) first:

In the world of containerized applications, the storage layer is often treated as a black box. Developers run docker run or kubectl apply , and somehow, the files appear. But beneath the surface lies a sophisticated ecosystem of snapshots, layers, and mount points. For those managing Kubernetes clusters using the Container Runtime Interface (CRI), understanding and the critical role of the link (symbolic or hard link) is not just an advanced skill—it is a necessity for debugging, performance tuning, and disaster recovery.

Recent Kubernetes enhancements (CSI snapshotting, image volume sources) are adding new layers of linking. The ImageVolumeSource feature (alpha in 1.29, beta in 1.30) allows mounting container images as volumes directly into pods. Under the hood, the CRI runtime creates a symbolic link from the pod’s volume path to the read-only image snapshot.

crictl allows administrators to check pod status, inspect image layers, and view container logs directly on a node without using the Kubernetes API server.
