      Did some googeling and testing, but could not get the ISO repository to connect.
      Finally simply deleted the repository and created a new one to the same samba share. That worked at once.

      Think I might have created the issue myself bij not having ejected one "cd" from one of the vm's. Not sure is this was the cause, but will update my own documentation to eject all cd's first πŸ™‚

      • Another thing I noticed is my VM's I set to autostart at boot do not autostart anymore at all.

      I already tried removing and setting the autostart option again for those vm's in XO, but after a reboot they still do not autostart

        @olivierlambert Sorry. I'm new to this. Can you point me to a description of how it should look? Thanks. I appreciate your patience.

            @gdixon so I just added a virtual disk to an XCP-ng 8.1 VM (I often use nested virtualisation for testing) that appeared as sdc. I connected that XCP-ng host to Xen Orchestra and used XO to create an ext SR.

            That SR was created as ext4. No need for sm-additional-drivers for ext4 in XCP-ng 8.1.

            Extract from fstab

            /dev/mapper/XSLocalEXT--d0866df5--f9fe--2c3a--1332--8d549468dce7-d0866df5--f9fe--2c3a--1332--8d549468dce7 on /run/sr-mount/d0866df5-f9fe-2c3a-1332-8d549468dce7 type ext4 (rw,relatime)
            

            Note: even for ext local SRs, XCP-ng uses an LVM layer on top, hence the output of lsblk.

              About VM autostart: as @r1 found out, there's a missing symlink in an XCP-ng updated via yum. That's a bug in the upgrade scripts that is present in CH 8.1 too, and we reported it to them.

              Here's the fix:

              systemctl enable xapi-wait-init-complete.service

                great find! I tested this, and it appears to at least correct the issue with autostart.
                Thanks

                      Indeed, also we reported the problem to Citrix, they might provide a fix one way or another.

                        Announcement about our former experimental ext4 SR driver:

                        It is now deprecated in 8.1. For a good reason: in XCP-ng 8.1 and above, following upstream changes, the ext driver now formats new SRs as EXT4.

                        There is no easy way to convert an existing SR created with our driver, so those using it will need to move the VDIs out (to another SR or to export them), destroy the SR and create an EXT SR instead. Make sure to do this on XCP-ng 8.1.

                        The sm-additional-drivers package remains available in XCP-ng 8.1 in order to ease the transition (update: and also because it contains the XFS driver). However I've broken the sr-create command on purpose. Any attempt to create a SR of type ext4 will result in an error with a message that explains that you need to use the ext type instead.

                        Our experimental driver will be completely removed in a later release, possibly XCP-ng 8.2. Unless someone convinces me to delay the removal for a good reason. I will accept reasons such as "I know I shouldn't have used the experimental driver in production, but I did and need more time to convert my SR while at the same time I really need feature xxx from XCP-ng 8.2", but I really would prefer to drop it in 8.2.

                        Feedback from people doing the transition is welcome to make sure we document the transition in the best way possible.

                          what's the status of the xfs driver? Are you expecting that to be removed/deprecated as well?

                            No, it's still there and still working but not officially supported.

                              New leaf coalesce logic using dynamic limits

                              I have backported patches from sm's master branch, that implement a new, smarter, logic for leaf coalescing.

                              Just update your 8.1 beta, restart the toolstack, and that should be it.

                              Those interested in the patches, see https://github.com/xcp-ng-rpms/sm/commit/ed1a55d727846cf5777c8258e6a8f3b068e8a35b (python code).

                                  All my SRs are using the ext4 driver.

                                  So I just need to export the VMs, (to a NAS for example), destroy the SR, and recreate the SR, then import the VMs?

                                  I guess I’ll need to use XCP Center for this since I use XO community running on the SR that needs to be destroyed/recreated in a Debian VM.

                                    Did anyone try VM export/import to see how much the performance has been improved?
                                    More interesting would be if someone tried it with 10G or making backups with XOA.

                                          I’ll wait till 8.1 drops before I mess with changing SR storage types.

                                            That kernel update is already available on 8.1 indeed, through yum update.
