Hello everybody, happy Monday.
I’m hoping to get a little help with my most recent self-hosting project. I’ve created a VM on my Proxmox instance with a 32GB disk and installed Ubuntu, Docker, and CosmOS to it. Currently I have Gitea, Home Assistant, NextCloud, and Jellyfin installed via CosmOS.
If I want to add more services to Cosmos, then I need to be able to move the containers from the VM’s 32GB disk into an NFS Share mounted on the VM which has something like 40TB of storage at the moment. My hope is that moving these Containers will allow them to grow on their own terms while leaving the OS disk the same size.
Would some kind of link allow me to move the files to the NFS share while making them still appear in their current locations in the host OS (Ubuntu 24.04). I’m not concerned about the NFS share not being available, it runs on the same server virtualizing everything else and it’s configured to start before everything else so the share should be up and running by the time the server is in any situation. If anyone can see an obvious problem with that premise though, I’d love to hear about it.
Your goal isn’t super clear from the post.
Are you asking how to host an OS on an NFS share?
So I have a 2TB nVME for VM Host Disks, and a 72TB RAID Array on my server. My hope is to have the OS and Docker on the 32GB drive I set up for the VM (which lives on the nVME), and then all the files related to the webapps live in a folder on RAID Array in a section meant just for that.
But the other responses in this thread make me think that’s not really going to be an option. Maybe I could make a very large VM Host Disk and put it on the RAID Array, let Docker just forget about the mount points entirely…
Have you looked into iscsi?
Alternatively you could run bare metal Proxmox and then add NFS as guest storage.
Keep in mind you may be limited by network. If you really want fast performance you need the proper hardware.
