Planning on setting up Proxmox and moving most services there. Some questions

Edgarallenpwn [they/them]@midwest.social to Selfhosted@lemmy.world – 60 points –

I am currently running most of my stuff from an unraid box using spare parts I have. It seems like I am hitting my limit on it and just want to turn it into a NAS. Micro PCs/USFF are what I am planning on moving stuff to (probably a cluster of 2 for now but might expand later.). Just a few quick questions:

  1. Running arr services on a proxmox cluster to download to a device on the same network. I don't think there would be any problems but wanted to see what changes need to be done.

  2. Which micro PCs are you running? I am leaving towards HP prodesk or Lenovo 7xx/9xx series around 200 each. I don't really plan on getting more than 2-3 and don't run too many things, but would want enough overhead if I switch stuff over to home assistant and windows and Linux VMs if needed.

  3. Any best practices you recommend when starting a Proxmox cluster? I've learned over time it's best to set it up correctly than try to fix stuff when it's running. I wish I could coach myself from 7 years ago now. Would of saved a lot of headaches lol.

For your Proxmox cluster shoot for three devices. With three devices you can do high availability which is a bonus but not something I though to do when I built my setup.

And you don't have quorum issues any time a system is down. (I regret making mine a cluster.)

You can set up a qdev on a pi or something.

I need to re-ip both of my proxmox hosts and ran into a wall due to quorum. This could get me over that hump.

That being said, it was a failed experiment to put them in a cluster. I don't use any of the cluster functionality and would love to destroy the cluster config w/o having to rebuild the proxmox hosts.

You donโ€™t have to rebuild the proxmox hosts to remove the cluster. I made the same mistake last year sometime and was able to remove the cluster and each of the proxmox machines works as it should standalone. I donโ€™t recall the exact steps but it was very easy. A quick search for โ€œproxmox remove clusterโ€ gave me this result and from what I recall these are the steps I followed as well. https://rostislavjadavan.com/posts/promox-delete-cluster
