Comment on Move UnRaid from metal to Proxmox
pyrosis@lemmy.world 4 months agoTo most of your comment I completely agree minus the freedom for choosing different disk sizes. You absolutely can do that with btrfs or just throwing a virtual layer on top of some disks with something like mergerfs.

You’re correct, with a bit more know how and knowledge it’s completely doable. Quick question maybe, once you create a pool and are utilizing it, are you able to add/remove drives as needed or does that require additional work to be completed? I am under the impression that the pools can be created with a variety of drives but making any physical adjustments are a bit of trouble.
However, I do appreciate you posting about this, maybe it’ll help someone else that might be browsing through here. Thank you.

It depends on your needs. It’s entirely possible to just format a bunch of disks as xfs and setup some mount points you hand to a union filesystem like mergerfs or whatever. Then you would just hand that to proxmox directly as a storage location. Management can absolutely vary depending how you do this.
At its heart it’s just Debian so it has all those abilities of Debian. The web UI is more tuned to vm/lxc management operations. I don’t really like the default lvm/ext4 but they do that to give access to snapshots.
I personally just imported an existing zfs pool into proxmox and configured it to my liking. I discovered options like directly passing datasets into lxc containers with lxc options like lxc.mount.entry
I recently finished optimizing my proxmox for performance in regards to disk io. It’s modified with things like log2ram, tmpfs in fstab for /tmp and /var/tmp, tcp congestion control set to cubic, a virtual opnsense heavily modified for 10gb performance, a bunch of zfs media datasets migrated to one media dataset and optimized for performance. Just so many tweaks and knobs to turn in proxmox that can increase performance. Folks even mention docker I’ve got it contained in an lxc. My active ram usage for all my services down to 7 gigs and disk io jumping .9 - 8%. That’s crazy but it just works.
