Implements automated cleanup for stuck terminating pods and prevents StatefulSet restart failures caused by stale lock files in the telemetry namespace.
Changes Made
🆕 New Features
Automated Pod Cleanup CronJob
Runs every 5 minutes to detect and force-delete pods stuck in terminating state for >60 seconds
Removes finalizers and performs graceful cleanup
Includes proper RBAC (ServiceAccount, ClusterRole, ClusterRoleBinding)
🐛 Bug Fixes
StatefulSet Lock File Cleanup
Added initContainers to clean stale lock files before pod startup
MySQL: Removes .sock and .pid files from /var/lib/mysql/
VictoriaMetrics: Removes flock.lock from data directories
Prevents pods from failing to start after ungraceful shutdowns
🔧 Configuration Updates
PVC Access Mode Change: Changed from ReadWriteMany to ReadWriteOnce for:
MySQL database PVC (
idrac_telemetry_statefulset.yaml.j2
)
VictoriaMetrics storage PVC (
victoria-cluster-vmstorage.yaml.j2
)
Reason: StatefulSets require RWO, and single-pod access pattern doesn't need RWX
