Best practice for mounting usb storage in Proxmox (feddit.uk)

I've got 3 HDDs connected to my Proxmox machine via usb3. They worked fine until this week. I have them mounted and passed through to OMV.

One failed on Sunday. It was fine one minute, I rebooted and Proxmox wouldn't boot...

Couldn't work out why it wouldn't boot and reflashed Proxmox, losing all my machines (I have since learned the importance of backups since I had none).

I've spent 4 days rewriting it all. Rebooted last night and it happened again, but this time I noticed that it was struggling to find one of my drives and edited them out of Fstab and got it booting again.

I've since added 2/3 drives back in by adding "nofail" to my Fstab entries but my main storage drive is now showing as 100gb instead of 1tb and won't pass through to OMV.

I've come to the conclusion that they were mounted by label and "forgot" their label, hence wouldn't boot, they're now mounted by UUID.

So has anyone got any tips on the best way to mount these things without killing my whole setup?

Also if anyone knows why my storage is showing as 100gb in Proxmox and won't pass through to OMV now I would be eternally grateful. Kinda want to get the files off that drive...

If you've got a m.2 slot in the mini PC you could add a cheap 5 sata port m.2 and connect them that way. If you don't want to solder power you could really make it a butcher job and hack up the power from the sata to usb connectors.

Sucks to hear about your loss, I've recently lost my proxmox setup and migrated everything to Nixos. My install threw a wobbly, terminal was cooked, could only ssh into some containers so I wiped the install and migrated.

In my proxmox setup I found it easier to mount the drives as lvm to the host proxmox machine and pass them through to lxc via bind-mounts rather than adding another layer of shares / overheads.
