      Was having a few issues with my XenServer this morning. The host itself eventually froze up with this:

      0_1525707946875_ae52ef19-f52d-4702-836f-87c288808af4-image.png

      So I rebooted it. It took a long time for it to come up, and then it booted into Emergency Mode.

      It boots off a 64GB USB stick. The VMs are stored on a 1.8TB SSD array (DELL H710).

      Here is the first thing it says in emergency mode:

      0_1525708016803_677cf0a6-72d3-4202-892b-b29bff4accb8-image.png

      And here is a listing of the drives and partitions.

      Anyone have any thoughts? sbd is a unused partition I am considering reinstalling XS on to see if I can re-see the array. But thought I'd maybe see if it is fixable first.

      Though wondering if the USB drive just finally gave up the ghost.

        I've had this happen in my lab, and it's always been resolved by reinstalling and the USB drive is usually dead and unable to be used elsewhere.

          This is where, if you can you would install to a new USB (though not recommended) and then mount your storage to XS. Once everything is back up and running you would then clone the USB so you'd have a spare USB and test it.

          When you run updates to XS, you would then need to again clone the USB and test the new clone.

          It's a bit of a pain in the ass, but this way you'd always have a working USB copy of your hypervisor for when your USB shits the bed.

            Yeah, that is what I am wondering.

              My recommendation would be, if you could to install to a HDD that is inside of the server, the USB route, while possible, just isn't worth the added time to clone and test the USB device every time you update.

                The culprit is likely that you'd didn't point your logs to a different directory, and those logs being written destroyed the USB.

                  XenServer was never meant to be installed on a USB.

                    RE: XS on USB comments ... trust me, I'll never do it again.

                    🙂

                      No logs written to USB.

                      We spent forever going over all that, remember?

                        I don't remember, but in any case XS reading/writing to the USB killed your boot device
