[Beginner] Proxmox & storage configuration

Submitted ⁨⁨4⁩ ⁨months⁩ ago⁩ by ⁨dwindling7373@feddit.it⁩ to ⁨selfhosted@lemmy.world⁩

Hi,

I’ve been playing with a Dell mini PC (OptiPlex 7070) that I set up with Proxmox and a single Debian virtual machine that hosts a bunch of containers (mostly an *arr stack).

All the data resides on the single SSD that came with the machine, but I’m now satisfied with the whole ordela and would like to migrate my storage from my PC to this solution.

What’s the best approach software side? I have a bunch of HD in of varying size and age (therefore expected reliability) and I’d initiallt dedicate such storage to data I can 100% afford to lose (basically media).

I read I should avoid USB (even though my mini PC exposes a USB-C) for reliability, but on the other hand I’m not ruse what other options I have that doesn’t force me to buy a NAS or properly sized HD to install inside the machine…

Also, what’s a good filesystem for my usecase?

Thank for any tips.

I have also got a dell optiplex and Proxmox and a Debian machine with mostly Arr in containers.

I also have 3 old HDDs that I’m using for itz of various sizes (2x1tb and 3/4tb)

I have used a powered usb3 to sata connector to hook them up to the Dell.

I have had a gotcha from using usb that destroyed my setup.

I now have a working solution that will stop this happening again:

So I have 3 usb-sata HDDs hooked in via the usb ports. I set up Open Media Vault as a VM. Then I passed through the USB drives to the OMV VM.

Those drives are then shared via SMB (I’ve just added NFS) to everything that needs it via the OMV VM.

I can then access the HDDs via this SMB share in Proxmox for backups if that’s what you wanna do.

Now the reason I’ve done it this way is because originally I had the drives in Proxmox. I gave them names and then put those names in the Fstab of Proxmox. One of the drives “forgot” it’s name and Proxmox wouldn’t then boot because one of its drives wasn’t accessible.

You could get around this by adding an option to the end of your fstab, I think the option is “nofail” but I’m not 100% so just check up on it.

I’ve used this option in my Debian VM Fstab to mount the NAS drives so my Arr stack can see them, and even got my Squeezebox server using them too. I’m using CIFS so I can see the drives on my Windows PC so I can manage the storage on my desktop.

So there you go, usb HDDs with passed through usb sockets to OMV VM is how I do it.

  I’m not familiar with using USB drives, but on any bare-metal system don’t use /dev/sdX but instead use /dev/disk/by-id/<big long disk identifier> in your fstab/cryptab etc. Even if you switch ports/bays, or your devices come up in a weird order after a reboot, config always points to the same physical disk. Way less stuff breaks.

  There a dozens of us!
  
  So I guess I can build a new VM and this won’t impact too heavily on my computational power (mostly Jellyfinn streaming 1080p stuff), correct?
  
  Is there any way around the impending… running out of USB? Would a usb-C dongle be a nono?
  
  Either way, thanks for the great answer.

    Yeah the new VM should just draw from your remaining RAM. My Debian VM is only using a few GB (6? 8?) but my Dell (I have a 7050 so it can’t be so different from yours) still has 10gb to play with.
    
    As for the running out of USBs I guess you could run a usb hub to one of the usb ports and just pass through the one, although I don’t know if that would break something.
    
    I don’t think they do a powered usb c to sata but I could be wrong. I’ve used 3/4 of the ports on the back for HDDs, on for my ZigBee stick for Home Assistant VM and have one spare plus the usb C. I have passed that usb C through to a VM for a usb c to 3.5mm (to send music to speakers) in the past though.
