        @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:

                          [21:15 uk ~]# drbdsetup status xcp-persistent-database
                          xcp-persistent-database role:Secondary
                            disk:Diskless quorum:no
                            uk.dc1.xcp-ng-hyper2 connection:Connecting
                            uk.dc1.xcp-ng-hyper3 connection:Connecting
                            uk.dc1.xcp-ng-hyper4 connection:Connecting
                          

                          Host2, 3 and 4 has

                          [21:18 uk ~]# drbdsetup status xcp-persistent-database
                          # No currently configured DRBD found.
                          xcp-persistent-database: No such resource
                          

                          kern.log files host1
                          host1_kern.log.txt

                          kern.log files host2
                          host2_kern.log.txt

                          kern.log files host3
                          host3_kern.log.txt

                          kern.log files host4
                          host4_kern.log.txt

                          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

                            @fred974 I'll take a look at the logs. Thanks. What's the ouput of lvs? If the database is not active, execute: vgchange -ay linstor_group.

                              @ronan-a said in Lost access to all servers:

                              If the database is not active, execute: vgchange -ay linstor_group.

                              How do I know if the database is active or not?

                                @ronan-a did you get a chance to review the log? Did you see anything that can help me move forward?
                                Thank you

                                  @fred974 I was a little bit busy, I can take a look at your problems tomorrow.
                                  In the worst case, do you have a way to open a ssh connection to your servers?

                                    @ronan-a thank you very much. Do you want me to open a tunnel via Xen Orchestra?

                                          It would be great, if you could write down some lines about the issue and how it could get fixed

                                            @KPS The DRBD volume of the LINSTOR database was not created by the driver. We just restarted few services + the hosts to fix that. Unfortunately, we have no explanation for what could have happened. So unfortunately I don't have much more interesting information to give. However if a person finds himself again in this situation, I can assist him in order to see if we can obtain more interesting logs.
