Promox, OMV and USB disk enclosure - how to set-up

[LameDuck]

Dear community

I've only just started using Proxmox. The installation of Proxmox went well. But after that...

I would like to set up a small NAS for home use. For this purpose, two SATA HDDs are available, which I connect via a USB Box to a mini-PC (USB only, no SATA) as my Proxmox server.

Installing OMV gave me headaches and some unsuccessful attempts. Can you give me some tips on what the structure should look like? Maybe I can read about it in the forum. I've already searched but haven't found answers (however the same question). My thoughts: OMV as VM or LXC? What do I do with the HDDs? Raid1 in USB harddrive enclosure? Raid1 in Proxmox and pass one virtual disk to OMV? Pass both disks through to OMV? Spindown etc should work. SMART data should be accessible. The NAS system is to be backed up to an external storage device in a time-controlled, automated manner and selected files are to be replicated to a cloud. In case of hardware failure I would like to be able to read one HDD on another Linux system. I suspect a direct connection to a Windows PC is not possible. Can you give me tips or sources where I can find out more? Is there a special AI that can support me at this point? Thank you very much, cheers Thomas

Hey,

what you could do is pass the USB port through to a VM directly, so the OMV is completely in control of the disks. Just keep in mind that if you want VM backups to also include the data on the disks you will have to first add them as a storage to PVE and assign a virtual disk on that storage to the VM.

Also, generally, you really don't want USB for things like this, but I guess you are already aware if that.

Thank you, Hannes, for your support. You're right, I know about the limitations of USB. I just had that spare mini PC ... I'll give it try and see what will happen.

I ve finally chosen OMV as VM and Hardware Raid1 within Terramaster enclosure.

The issue with giving the whole disk(s) to the VM like that is that snapshots or backups don't include that storage then.
