So here is the issue at hand for me. I have 8 sata ports on my mobo and they are split into 2 iommu groups. I have 4 drives going to truenas when it boots by passing it through to the VM. Now I added a 10tb hard drive I wanted proxmox to use only and put it on the other set of sata ports so it is in group 19 well the truenas drives are in 20. It looks fine when I booted everything up till I went to make backups to the group 19 10tb drive which had flipped into read only mode. I tried to unmount and remount which it wasn't letting me do.
Does anyone have suggestions or is this just how iommu pci splitting is going to work?
