Proxmox Storage Upgrade: When SAS RAID10 Beats SSDs
A field note on choosing capacity over flash performance for an older Proxmox host, including RAID10 math, controller risk, cost, and migration impact.
Proxmox Backup Is Not Disaster Recovery Until Restore Works
A recovery-first field note: an earlier VM restore was unsatisfying, so compare Veeam, PBS and native Proxmox backup using the same isolated full-VM restore and host-rebuild criteria.
How to Migrate a Stateful App from a VM to k3s: A Cutover Checklist
A practical, evidence-based VM-to-k3s migration checklist from a real Snipe-IT cutover: independent backups, data verification, NFS writes, TLS testing, DNS change and rollback.
Kubernetes Disaster Recovery: Why an etcd Snapshot Is Only One Layer
A field note from a small k3s environment: etcd snapshots matter, but credible recovery also needs the original server token, GitOps state, database backups, persistent file protection and restore evidence.
Kubernetes Developer Platform: 7 Design Decisions for a Small k3s Cluster
A practical design note for building a resource-constrained Kubernetes developer platform on an existing k3s cluster with Rancher, isolated namespaces, quotas, dedicated workers and automatic cleanup.
QNAP NFS Permissions: 9 Reliable Checks for Non-Root Kubernetes Containers
A real troubleshooting sequence for QNAP-backed Kubernetes storage when root can write to an NFS PVC but the non-root application user receives Permission denied.
Hybrid Kubernetes: 3 Practical Options for k3s and Azure

k3s Migration: 7 Practical Rules for What Moves—and What Stays on VMs
This k3s migration inventory produced seven practical rules for deciding what belongs in Kubernetes, what stays on a VM and what should be retired.
Designing Real k3s High Availability Across Proxmox Failure Domains
Four worker nodes looked redundant until I mapped them back to the single Proxmox host underneath. This is the HA redesign before more workloads move to k3s.
