Reflections on Proxmox VE

I’ve now been using Proxmox VE as a hypervisor in my home lab for a couple of years, and as I’ve reverted to plain Ubuntu Server + KVM, I figured I would try to summarize my thoughts on the product. Proxmox VE can be described as a low-cost and open-source alternative to VMware vSphere with […]

ZFS backups in Proxmox – Part 2

A while ago I wrote about trying out pve-zsync for backing up some Proxmox VE entities. I kept using regular Proxmox backups for the other machines, though: It is a robust way to get recoverable machine backups but it’s not very elegant. For example all backups are full: There’s no logic for managing incremental or […]

ZFS backups in Proxmox

I’ve been experimenting with using ZFS snapshots for on- and off-site backups of my Proxmox virtualization environment. For now I’m leaning towards using pve-zsync for backing up my bigger but non-critical machines, and then using syncoid to achieve incremental pull backups off-site. After the initial seed – which I perform over a LAN link – […]

Some short notes I made along the way to benefit the future me. Background On my new server, Proxmox was unable to boot directly to a ZFS file system on a drive connected via the HBA controller. UPDATE (2020-01-27): The SuperMicro X10SRH-CLN4F motherboard boots just fine from a root-on-ZFS disk in UEFI mode from the […]

Replacing ZFS system drives in Proxmox

Running Proxmox in a root-on-zfs configuration in a RAID10 pool results in an interesting artifact: We need a boot volume from which to start our system and initialize the elements required to recognize a ZFS pool. In effect, the first mirror pair in our disk set will have (at least) two partitions: a regular filesystem […]
