Symptom & Impact

Container runs fail with `error mounting overlay` after a node reboot or storage failure.

Environment & Reproduction

Common when /var/lib/containers/storage is on a filesystem that does not support overlay metadata.

Root Cause Analysis

Overlay layers reference stale upper directories or filesystem capability mismatches.

Quick Triage

Run `podman info –debug` and check the configured storage driver.

Step-by-Step Diagnosis

Validate the backing filesystem supports overlay (xfs with ftype=1 or ext4).

Solution – Primary Fix

Run `podman system reset` after backing up data, then pull images and recreate containers.

Solution – Alternative Approaches

Switch to `vfs` storage driver as a temporary fallback for diagnostics.

Verification & Acceptance Criteria

`podman ps` lists containers running and image pulls complete without overlay errors.

Rollback Plan

Restore /var/lib/containers from snapshot if container data must be preserved.

Prevention & Hardening

Provision a dedicated XFS volume for container storage with `ftype=1`.

Related Errors & Cross-Refs

Often paired with cgroup v2 quirks and SELinux denials on container mounts.
