      I assume the RPU will also take care of outstanding patches on the host, is that correct?

        @fatek Yes, it should evacuate each host, starting with the pool master. Then patch the host, followed by a reboot.

          @Danp The RPU did not patch the hosts, all hosts still show outstanding patches.

          I'll reboot all the hosts maybe they just need a 'lil kick in the ass!

            @fatek said in Rolling Pool Update - failing:

            CANNOT_EVACUATE_HOST

            This error means there's VMs that can't be live migrated elsewhere. In that case, RPU can't work.

            The details reason is the CPU version on which a VM booted. You probably added a host in the pool after booting some VMs, so they were using more advanced CPU feature than now available. The trick is to shutdown then immediately boot those VMs, and the problem will be solved.

              @olivierlambert That is what I was thinking as well, but the he said that all hosts had been rebooted the previous day. 🤔

                Even though the RPU showed a completed status of 22 mins, 1 of the 4 hosts was in emergency mode & 2 other's were disabled.
                I was able to fix the situation with the following commands:

                yum-complete-transaction --cleanup-only
                yum-update
                reboot

                  That's weird 🤔 So you have things unfinished in yum?

                    Yes, it said there were a few uncompleted transactions in yum,
                    After cleanup operation, I was able to patch the hosts, reboot & now it's time to install XOSTOR 1.0!
                    *remember, I'm on xcp 8.3 beta 2

                      About XOSTOR on 8.3: you'll hit bugs, it's not fully up to date, because we prioritize bug fixes on 8.2. So as long it's test and not prod, that's fine 😛

                      edit: for yum we have identified something that XO could fail without waiting for yum to finish, it will be solved ASAP

                        It is test not prod.
                        Next week, I'll probably tear it down & re-install with 8.2
