I don’t use it so I can’t recommend it, but if you’re interested in other options to research there’s a mergerfs+snapraid combo.

I currently pass through my disks to an unraid VM and then mount them through nfs which works (but from the sounds of it probably not a valid option for you, not would I recommend it), but I want to try replacing it with mergerfs at some point.

The thing that has mainly turned me off of zfs is (from what I understand) that you kinda need to plan how you’re going to expand when you set it up. Which really doesn’t work for me with a random collection of disks of varying sizes.

Another note for option 1, since proxmox 8.4 there is virtiofs which would allow you to mount a folder to a VM without having to go through nfs. You may have to mess with selinux in the VM depending on what you do in there, but just fyi it’s a thing.

Does it have deduplication enabled? Afaik that’s the functionality that the high memory footprint is usually quoted.

(Also, was that meant to be 170TB?)

I can’t say I know the answer but a few ideas:

• did you access it with a browser? Maybe it snitches on you or some extension does?
• did you try to resolve it with a public DNS server at any point (are you sure nothing forwarded the request to one)?

You could try it again, create the domain in the config and then do absolutely nothing. Don’t try to confirm it works in any way. If you don’t see the same behaviour you can do one of the above and then the other and see when it kicks in. If it gets picked up without you doing anything…then pass!
