I'll add some more on this.
I did attach the task log here.
.tasklog.txt
Now I did have to restart the toolstack as I wasn't able to cancel the migration task (after it hung). As stated, it hangs at 99% and says "estimated 3 minutes" to complete. I have left this run for over an hour but still says 99%.
I have tried this multiple times but get the same result. Support did mention to try and kick off the import via CLI which was tried in my last attempt. Unfortunately, same result.
I'm new to XCP, but you mention "xo should say something about " nbdkit logs of ${diskPath} are in /tmp/xo-serverxxxx" do you know where exactly I can pull those? Tried looking under /var/log of XOA but not seeing what you mention.
Side note. After restarting the toolstack and going into storage I could see the drives for that server. For testing I did create a new VM and attached those existing disks. The VM did boot up and the data drive was there and accessible. Though skeptical as technically the migration of that drive didn't get to 100%.
