      I need to reboot one of my host servers which is the pool master. There are no VMs on it. I went to Change the pool master to another server last night and got the error "Internal Error - Missing Column". The Pool master has been updated along with 2 (Out of 4 total) of the other host have been updated. The host than I am trying to move the pool master to is up to date as well.

        Hi,

        You don't switch the master while doing upgrades in a pool. Just reboot it.

          @olivierlambert Ok, just reboot the master won't cause any issues?

            No, it's perfectly fine to reboot the master. Obviously, without HA enabled on the pool.

                I rebooted the pool master. Even though it looks like it came up ok it is not connected to storage. In xcp-ng center it is showing a red X for the SR and this is the errors in dmesg.

                  You have an issue with your storage configuration. It's hard to tell more without knowing more or digging more.

                    @olivierlambert Dang ok. I waited a few minute then clicked the Connect in XOA for that host and it connected. Not sure what to do really.
