          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.

                                  Not yet but I'd be really grateful to anyone who could benchmark this!

                                    So, the main remaining development before RC is an updated installer to allow it to boot the alternate kernel in cases where the main kernel has issues. And also an option to boot with only 2G of RAM to workaround Ryzen APU "black screen" issues.

                                      last week I installed a new server XCP-ng 8.1. But the filesystem is still Ext3. (by the way XO connects without problem but you need XCP-ng Center Development build to access)
                                      Today I will install a new server, what should I do to get ext4 in the filesystem?
                                      Thanks

                                        What do you mean? SR file system or root filesystem?

                                            I don't think you should trust XCP-ng Center on this. What do you think @borzel?

                                            Check the output of mount instead.
