OMV 7 — Part 5: Lock the PVE Kernel and Prevent ZFS-Breaking Updates
Running ZFS on OMV 7 requires the Proxmox VE kernel. The problem is that Debian does not know that. A routine apt upgrade will happily pull in a stock Debian kernel, and after the next reboot your ZFS pools fail to import. This post covers how to lock the system so that cannot happen. Why…

Installing OpenMediaVault 7 on a Dell PowerEdge R620 — Lab NAS Build
The Dell PowerEdge R620 sits at the back of my lab rack doing one thing: storage. Twelve drive bays, a flashed-to-IT-mode PERC H310, and ten 1 TB SAS spinners make it a solid NAS candidate. OpenMediaVault (OMV) is my NAS OS of choice — Debian under the hood, web UI on top, no licensing fees,…
