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 @[email protected] mentioned and your IO delay will be unbearable. I use Intel enterprise SSDs and have no issues.

Not sure where you're getting that. Been running ZFS for 5 years now on bottom of the barrel consumer drives - shucked drives and old drives. I have used 7 shucked drives total. One has died during a physical move. The remaining 6 are still in use in my primary server. Oh and the speed is superb. The current RAIDz2 composed of the shucked 6 and 2 IronWolfs does 1.3GB/s sequential reads and write IOPS at 4K in the thousands. Oh and this is all happening on USB in 2x 4-bay USB DAS enclosures.
