    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)

    @limezest said: ISOs in my NFS ISO SR The simplest way to correct those is to forget the VDI and then rescan the SR. Note: The ISO names will be lost if they were uploaded via XOA, which causes them to be renamed to .IMG files.

    @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.
