      1 of our 5 servers went down and now can't be saved due to VDI Chain error and occasionally restarts vm's.
      (The vm's were not stored on the server that failed)
      There is one vm that is stuck and I can't delete it, surely it is related.
      I read on forum as a temporary solution to copy and migrate the vm, but of course after a few days it will fail again.
      We are now going to put a freshly installed one in place of the downed server. I've had this problem for a few weeks now and haven't found a solution to solve it, can anyone help me? 🙂

        Look under Dashboard > Health tab in XO to see if you have VDIs listed in the Unhealthy VDIs section. You may have a storage issue that is preventing the coalesce process from completing successfully.

          I'm sorry I'm just now writing back, this is what the interface is giving. I also tried "rescan all disks".

              I also restarted the toolstack on each of our servers.

                @Nephilim You should check the contents of SMlog on the pool master. You can use the following to locate any exceptions ---

                grep -A 5 -B 5 -i exception /var/log/SMlog

                            But this is still wrong. What can I do with this?

                              There isn't anything wrong on that screen. It simply is showing a list of XO tasks that (mostly) haven't succeeded.

                                  @Nephilim Nothing shown here would indicate a problem AFAICS.

                                  P.S. Added proper markup to your post
