Question on Proxmox Pools (I'm a bit of a noob) (lemmy.world)

I've added 2 external USBs of 2TB each to my Proxmox server and created a Resource Pool called USB_HDD containing both. I created an Ubuntu VM, but I can't allocate all 4TB to it in one go - it only allows me to add each one as a separate SCSI device. When I start to install the OS it only allows the install onto one of the 2TB devices. I though the point of pools was to make the actual disks transparent, and present the pool to the VM so it sees it as one lot of space. Am I doing something wrong, or do I have to have it as 2x2TB disks?

I believe a resource pool, is just a group of resources, so adding a resource pool of 2 devices is exactly the same as adding those 2 devices manually, (I normally use them as VM groups to backup though).

You might be able to do striping (combining 2 devices into 1) using ZFS in Proxmox, or I think LVM can but you'd be using the command line.
