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?
If I recall correctly it’s important to be running ECC memory right?
Otherwise corrupter bites/data can cause file system issues or loss.
I think ecc isn’t more required for zfs then for any other file system. But the idea that many people have is that if somebody goes through the trouble of using raid and using zfs then the data must be important and so ecc makes sense.
You recall wrong. ECC is recommended for any server system but not necessary.
