      Well it's either RAM (4 short fast BIOS Beeps) or the board is bad.

      Which would suck.

            But the critical point is that it's stupidly simple to recover from this.. Stupidly simple.

            VM Says: "Oh you have another Xen Server, yeah I can run over there in the mean time. "

                So this is what I'm not present with, the server finally gets past post, but won't get past this.

                Anyone have any pointers?

                  That doesn't look good. It looks like it's not seeing md0. You might have to boot from a USB and do some troubleshooting.

                    Yeah (fortunately) this system was hobbled together so it's single disks.

                    I'm going to attempt to mount them to a laptop running *nix and see what I can pull off.

                      Assuming a drive failure, try running SpinRite on it.

                        I'm thinking it was a memory issue, so the data on them might be OK.

                            How did you get past the memory issue, yet still have the error if it was a memory issue?

                                  Isn't this a test server?

                                    This was the production server that was budgeted together... fortunately I have recent backups of my VM's so now it's just a matter of rebuilding it.

                                      This was also before our topic on MDAD RAID 10.

                                        Are you going to rebuild it MDAD RAID 10?

                                          Going to attempt to remount the disk in a clean install of Xen, save my self some time if I have to import what I want.

                                          There might be some good change with the build now that this happened. Like being able to spend appropriately.

                                            So I've got my SR reattached, just need to figure out how to import the VM's from the SR.
