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…

OMV 7 on Dell R620 — Part 2: Kernel, ZFS, 10Gb Networking and ESXi Integration
Part 1 got OMV installed and running on the R620.

The R620 has 384 GB of DDR3 — most of that becomes…
