    @rzr Updated and running on most systems now. Rolling pool reboot worked correctly (need to disable backups first). VMs and CR running normally. After a large S3 backup session (that succeeded), GC on the master got stuck in a loop and failed (lock issue). A reboot of the pool master was required to resolve the problem then GC coalesced the VHDs without additional action. Other pools did not have the same problem. I have not seen that issue before, but everything seems fine now so I can't blame the update.

    Hi @mdm, Here is the response from a SME 1- XO get the VM metadata through soap api and create the vm /network XO use the nbdkit + nbdkit-vddk package , connecting to each disk XO connect through NBD to nbdkit XO list the allocated blocks XO create the disk XO read the block and import the data into the disk (though a vhd or qcow2 stream depending on the size) 2- though XO. There is a lot of disk transform occuring here 3- not anymore, it was too brittle, especially on when the disk are locked or not. Also it was not scaling too well 4- see 3- + vddk transfer is overwhelmly faster that previous access through http, is compatible with VSAN and don't lock the disks. (+ also see https://xen-orchestra.com/blog/xen-orchestra-5-110/ section "VMware to Vates (V2V)" where we made key improvements)

    @nasheayahu so you're actually trying to import those QCOW2 VDIs, not creating them, right ? You'll have to wait for the import feature for QCOW2 which is coming soon. You should be able to create a brand new SR with QCOW2, but be aware of the known issue on ZFS with large VDIs (see https://xcp-ng.org/blog/2026/05/05/qcow2-is-now-ga-in-xcp-ng/). Did you install ZFS on your host ? see https://xcp-ng.org/blog/2018/08/03/xcp-ng-with-zfs/

    @Mathieu-L linstor n l was included in my original post. All nodes were updated to May 2026 Security and Maintenance Updates for XCP-ng 8.3 LTS, all nodes were restarted. May 2026 Updates #2 for XCP-ng 8.3 LTS was released, and a couple days later I installed on all hosts. No host restarted. When xen04 was restarted, that is when this issue happened. I had used systemctl restart linstor-controller here (https://xcp-ng.org/forum/post/105309) to restart the controller.
