Anyone running ZFS? (lemmy.fwgx.uk)

At the moment I have my NAS setup as a Proxmox VM with a hardware RAID card handling 6 2TB disks. My VMs are running on NVMEs with the NAS VM handling the data storage with the RAIDed volume passed through to the VM direct in Proxmox. I am running it as a large ext4 partition. Mostly photos, personal docs and a few films. Only I really use it. My desktop and laptop mount it over NFS. I have restic backups running weekly to two external HDDs. It all works pretty well and has for years.

I am now getting ZFS curious. I know I'll need to IT flash the HBA, or get another. I'm guessing it's best to create the zpool in Proxmox and pass that through to the NAS VM? Or would it be better to pass the individual disks through to the VM and manage the zpool from there?

ZFS is great, but to take advantage of it's positives you need the right drives, consumer drives get eaten alive as @scrubbles@poptalk.scrubbles.tech mentioned and your IO delay will be unbearable. I use Intel enterprise SSDs and have no issues.

Could this because it's a RAIDZ-2/3? They will be writing parity as well as data and the usual ZFS checksums. I am running RAID5 at the moment on my HBA card and my limit is definitely the 1Gbit network for file transfers, not the disks. And it's only me that uses this thing, it sits totally idle 90+% of the time.

For ZFS what you want is PLP and high DWPD/TBW. This is what Enterprise SSDs provide. Everything you've mentioned so far points to you not needing ZFS so there's nothing to worry about.

I won't be running ZFS on any solid state media, I'm using spinning rust disks meant for NAS use.

My desire to move to ZFS is bitrot prevention and as a result of this:

Looking back at your original post, why are you using Proxmox to begin with for NAS storage??

[–] blackstrat@lemmy.fwgx.uk 2 points 1 month ago

The server runs Proxmox and one of the VMs runs as a fileserver. Other VMs and containers do other things.
