      Hi all,

      I have a cluster of 4x host and suddenly, I lost access to all of the VM on the master.
      When I looked at it, the master host is saying that it hasn't got any NIC card

      cbb60d02-fb8d-4480-9566-f3c7bc8d2814-image.png
      But I am able to ssh to it.

      I have XOSTOR install but not used for production.

      Could anyone please advice on how i can get the system back online?

      On the other host I have the following
      366365b0-e086-4c2b-9f21-c91e55a4128f-image.png

      all the host can ping google.com

      Do I need to remove the host from the pool? how will that work with xostor?
      What log do I need to investigate

      I also get this on the screen

            @fred974 Hi !

            You can try a xe-toolstack-restart on the master, it will not harm your running VMs

              I am doing it now but I am not getting the cursor back
              Also got this:

              [12:09 uk ~]# xe host-is-in-emergency-mode
true
[12:09 uk ~]# xe pool-recover-slaves
The server could not join the liveset because the HA daemon could not access the heartbeat disk.

                    "Forget to say HA was enabled": that's the main information here 😆

                    Yes, disable HA first 🙂

                      @olivierlambert I disabled HA and set host 2 as new master and the NIC are showing again but I cannot ssh or access any VM. Including XO. In xcp-ng centre, all the host seem to be in maintenance mode.

                          @olivierlambert I got all the system back up and running now with HA disabled. I think that I need HA enable to get my XOSTOR SR to work again but I am not happy not understanding what happened today as xcp-ng gone wrong out of the blue. Cold you please tell me what I need to do to investigate the source of the issue?

                            @fred974 You can check in /var/crash if you have something, /var/log/xensource.log and /var/log/SMlog
                            And maybe a dmesg

                                          @fred974 Hi, well first, how many hosts do you have?
                                          We recommend to use at least 3 hosts, (4 is more robust). And also what's your replication count on your LINSTOR SR?
                                          I ask these questions because it's possible that a problem on a host has caused reboots on the whole pool and finally the emergency state.

                                          Now: can you share the kern.log files of each host? And execute this command (on each machine) please:

                                          drbdsetup status xcp-persistent-database

                                            well first, how many hosts do you have?

                                            We have 4x hosts.
                                            Host1 was the original master (host2 is new master) and I think the DRBD replication count is 3 (how can I double check?)
                                            Host1:

                                            Our monitor reported the first VM been down at 11am which is reflected in the log file. We also have ourly snapshot so I was wondering if this could also been the reason why. I hope the file above can help us understand the issue. Also, should I put host1 back as master?

                                            Thank you
