      My experience with "XOA Quick Deploy"

      It failed.

      Because I need to use a proxy, I opened an issue here:
      https://github.com/xcp-ng/xcp/issues/193

      cocoon created this issue in xcp-ng/xcp

      open XOA Quick Deploy with Proxy #193

        Installed fine on one of my Intel X56XX based system and the system boots into XCP 8.0 although the zfs local storage wasn't mounted and a repair fails as well.

        modprobe zfs fails with "module zfs not found"

        Is there any updated ZFS documentation for 8.0 that would help?

          zfs is not part of the default installation, so you need to install it manually using yum from our repositories. Documentation on the wiki has not been updated yet for 8.0: https://github.com/xcp-ng/xcp/wiki/ZFS-on-XCP-ng
          Now the zfs packages are directly in our main repositories, no need to add extra --enablerepo options. Just yum install zfs.

          I've just built an updated zfs package (new major version 0.8.0 instead of the 0.7.3 that was initially available in the repos for the beta) in the hope that it solves some of the issues we had with previous versions (such as VDI export or the need to patch some packages to remove the use of O_DIRECT). I'm just waiting for the main mirror to sync to test that it installs fine.

            @stormi Thanks for the quick reply .. tried the yum install zfs and it errors with the following:

              That's why I told that I'm waiting for the main mirror to sync 🙂
              And the build machine is having a "I'm feeling all slow" moment.

                      @AllooTikeeChaat yum considers that your medata are recent enough. Ask it to clean them: yum clean all.

                        @stormi yum clean all worked. Installed aok and modprobe zfs doesn't complain so that's all good.

                        A repair of the ZFS SR fails with the same error and "zpool status: no pools available" and "zfs list no datasets available".

                        I'll open a new post if I can't get it working rather than replying to this one.

                        Update: fixed the issue ..

                            (1) Missing the ZFS packages from the base install.
                            (2) Needed a "yum clean all" to be able to install zfs packages.
                            (3) Needed to manually import the ZFS zpool

                            I'm a noob with zfs so had to work out how to import an existing zpool and once thats done it can be repaired/mounted.

                              Good 🙂 So now you are on ZoL 0.8, no need to disable sync anymore 🙂

                                I'm assuming that sync is enabled by default ?

                                  Yup, but before (0.8) it wasn't good for performances, at all, due to cache poisoning (no O_DIRECT support).

                                    Any chance to get a newer lsblk that supports json output?
                                    Would be great for plugins and would make parsing output much easier.

                                    Currently installed on XCP-ng 8 beta: util-linux-2.23.2-52.el7_5.1.x86_64

                                    (something later than v2.27?)

                                    ... ah forget it, I see, CentOS is using the old versions since long time ...

                                      Yeah the chances that we'd change the version of such a low level package just for added functionality are very low.

                                        @stormi yes and I totally understand that ... I just thought at first, it is so old, there must be something new if CentOS 7.5 is new ... but no 😕

                                          hi

                                          Is this possible to install xcp-ng in xcp-ng just for tests?

                                            Sure you need to enable Nested Virtualization when you create your VM and that's it.
