      @coliver Pretty much.

      Since there is no hot-swap function on my server (no indicator lights either) it's simply a matter of my knowing which disk is connected to which SATA port.

        So at this point I have the disk marked as failed, and removed from the array as shown below.

        0_1453994344578_XenCenterMain_2016-01-28_10-18-57.png

        As you can see sdc is not a part of the array at the moment, which means nothing will be written to the disk. Obviously I'm in a dangerous point in time.

        If I can't get my replacement disk soon, I risk losing the entire array.

        Now, because I've ready had issues with this array (specifically the disk) I have nothing running on this system that I don't have several backups of. So the drive has been ordered and will be here in a day or so.

        At which point I'll shutdown the server, remove the bad disk, and put the new one in.

          While I wait for that drive to arrive, I'm going to figure out how to configure email alerts for the mdadm array. Seeing as this would be incredibly useful to have.

          Since I can't sit here watching the cat /proc/mdstat.... 🙂

            No remote ssh access?

              @travisdh1 I do have access, but I'm still not going to sit here and watch it.

                So now that I have the email alerts configured for my Xen Servers, I really want to work on updating SmartCTL so it supports the drives that I have in this server.

                Which are pretty common drives.

                Western Digital Red 1TB.

                I'm really surprised how old of a database is built into XenServer 6.5.

                So time to figure this part out.
