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 –… Continue reading ZFS backups in Proxmox
Moving Proxmox /boot to USB stick
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… Continue reading Moving Proxmox /boot to USB stick
It’s so fluffy!
(Or: Backblaze B2 cloud backups from a Proxmox Virtual Environment) Backups are one of those things that have a tendency to become unexpectedly expensive – at least through the eyes of a non-techie: Not only do you need enough space to store several generations of data, but you want at least twice that, since you… Continue reading It’s so fluffy!
Fixing lack of console video in Proxmox on HP MicroServer Gen7
After my latest experiment I encountered an issue where the current lack of video output from Proxmox on my N54L-based HP Microserver Gen 7 became a serious issue: I would see the Grub menu, then the screen would turn blank and enter power-save mode, I’d see the disk activity light blink a few times, but… Continue reading Fixing lack of console video in Proxmox on HP MicroServer Gen7
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… Continue reading Replacing ZFS system drives in Proxmox
