installed updates.... by accident i ran the linstore-testing updates. but no issues with the udpate itself.
I did download the snapshot-fixer.py in dry run it found to vms. I ran a full backup first and was going fine till here...

Here are some of the logs - if you have a place i can send the rest as i am not able to post all of them...

Dug into it some more. The stuck process is tapdisk pid 28167. tap-ctl list just hangs and tap-ctl list -p 28167 times out, but the other 3 tapdisks answer fine. It’s in S state, not D, so it doesn’t look like it’s waiting on the disk.
28167 is the one doing the NBD export of the backup snapshot for my Dockerthings_anepi VM (snapshot bf2a422e-9df3-4b3d-83f0-0fa3ff191efb, VHD on SR 4991d4aa...). That’s the export that stopped at 75%. Everything after it is stuck at 0% (VBD.plug, importing raw VDI, the XO-CE-root import), and when I tried force unplug those got stuck too. The backup job said it finished though, and the VM itself is still running fine.
Ran the snapshot-fixer dry run and it found 2 VMs. I did not run the rewrite before doing the backup.
Update went through fine at 05:58, all from xcp-ng-testing, and I rebooted at 06:00, so this happened on the new packages. The linstor-testing thing didn’t install anything, rpm -qa | grep -i linstor comes back empty. Attached the yum history.
I have the full logs (xensource, SMlog, daemon, kern) if you want them, just tell me where to send them.
yum-history-11.txt
Update: kill 28167 (plain SIGTERM, not -9) cleared it, then the stuck tasks cancelled without a reboot. Will post if it happens again on the next backup.
