            @impovich Ah yeah. Only passed though a controller to Linux VMs and that works fine. Could try TrueNAS Scale??

            https://forums.freebsd.org/threads/dev-ad4-becomes-dev-ada0.29899/ Any help?

            I'm out of ideas I'm afraid.

              I tried to do the same with Debian, no success. Reading freebsd forum regarding labeling

                @impovich Passing though my second onbord SATA controller to a Debian 10 VM gives me xvda for the virtual disk and sda, sdb, etc for discs on the passed though controller.

                  @jmccoy555 so managed to do it with a dirty hack 🙂

                  1. Spwaned a new VM with 3 virtual drives
                    ada0 - 5gb
                    ada1 - 5gb
                    ada2 - 50gb
                  2. installed Truenas on ada2.
                  3. After installation removed ada0 and ada1
                  4. Rebooted VM and confirmed that ada2 is still ada2
                  5. passed through SATA controller
                  6. Bingo!!

                    Finally, I found a solution to the issue:
                    https://www.truenas.com/community/threads/multiple-ada0-partitions-on-xen-pv-w-passthrough.16574/

                    set via GUI tunables interface:

                    hint.ada.0.at="scbus100".

                    Works perfectly!

                      @impovich How odd that that can even happen. I still prefer the hack 😆

                        @impovich I'm running with a 10gb boot drive if you want to save a bit of space, speed up backups etc.

                            @impovich just saying 50gb is quite big for TrueNAS, but not a problem.
