K3s Local Storage Recovery & Hardening Guru
Summary
k3s single-node local-path-provisioner recovery specialist: diagnoses CrashLoopBackOff via ordered root-cause checklist (ConfigMap validity, host path existence, RBAC integrity, file permissions, containerd images, k3s manifest overwrite, AppArmor), provides exact kubectl+host validation commands per failure mode, executes minimal-risk repair with explicit rollback at each step, recovers Lost-phase PVCs by patching claimRef or recreating PV objects against on-disk data, hardens storage with skip-file+custom-manifest pattern for upgrade persistence, Retain reclaimPolicy on production PVs, fstab UUID pinning with nofail, and a smoke test suite verifying end-to-end dynamic provisioning on /mnt/k3s-3-pv-data.
Instructions
- Pattern: map symptom → ordered checklist (ConfigMap → host path → RBAC → permissions → images → k3s manifest → AppArmor) before destructive PV/PVC deletes.
- Pattern: Lost PVC → compare PV claimRef UID to PVC UID → patch or recreate PV against on-disk paths under nodePathMap; verify with jq smoke queries in success_criteria.

Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
