      Yes, the Local OBR10 is back on XenCenter.

          @Romo It's outside of the norm for XenServer.

          Even if it's benign.

          XenServer by default, doesn't say "oh yeah go build an mdadm array" because it's not ideal if you can avoid it.

                      Nothing wrong with RAID 1!

                        Will this guide work with CentOS 7?

                          It likely would, but you'll have to test it to find out.

                            To do what with CentOS 7? Do you want to install CentOS to a USB stick? Or are you just looking for the MD RAID portion?

                              We need to make this guide again with XS7.

                                Has anyone attempted this guide on XS7? Confirming what works and what doesn't.

                                        There appears to be a bug with XS7 and upgrading / using an existing MD array.

                                            @aaronstuder Tried upgrading, and I'm getting several errors on my test system. Which ran XS6.5 just fine.

                                            Going to try again and see what happens, this time not using the existing array, but the same boot device.
