    Hey all. Bit of a snag. So I want to preface this with: I'm still getting into Proxmox a bit, and have made the jump from Hardware Raid through a PERC to just HBA mode and doing ZFS to leverage some of the benifits that it offers with the new server I've picked up recently. However, trying to...
