Hi all,

v1.17 of vbox contains some fixes for CVMFS configuration provided by computezrmle which should address some of the problems people see with stuck or not working CVMFS at the start of tasks. We are testing it here on dev just to make sure it works ok before releasing on the prod server.

Message 7827 - Posted: 19 Oct 2022, 16:38:47 UTC - in response to Message 7826.  

I tested several tasks. Not sure what problem should be solved.

https://lhcathomedev.cern.ch/lhcathome-dev/results.php?hostid=4600&offset=0&show_names=0&state=0&appid=5
On host id 4547 I had three errors. 1 was part of the first 5 tasks starting at once. On that task I got a popup of a vboxheadless.exe application error.

With 2 other tasks I tested the netwoork connection problem by interrupting my internet when starting an ATLAS task.
I got Testing CVMFS .... of course without response. The tasks keep on running endless.
After connecting to the internet again also nothing positive happened / tasks keep on running doing nothing.
So I suspended the tasks, removed the saved states, rebooted the VMs and saved the state after over 5 minutes of runtime.
Then I resumed the tasks in BOINC again.
1 task got the same VBoxHeadless application error as above and the other was canceled by the server although running well.

Looks fine.
All changes seem to work as expected.

For Win11pro, no tasks avalaible.
Ok, native parameter was active.
Running with 6 (10 Cpu's) tasks from production concurrently.

Using on the Threadripper no Squid.
If this solution is in production and running well,

Message 7830 - Posted: 20 Oct 2022, 7:43:46 UTC - in response to Message 7827.  

Not sure what problem should be solved.

1.
The starting order (systemd services) was undefined, hence random.
Now it's explicitly defined that an ATLAS job doesn't start prior to the availability of autofs (=CVMFS mounts) and the shared folder mount.

2.
Some quoting issues were fixed that affected the CVMFS fail-over.
old: fail-over didn't work when the backend behind s1cern-cvmfs.openhtc.io was down
new: CVMFS now correctly switches to a fail-over server and automatically back when the closest server is back

Theory and CMS are already updated.
ATLAS may follow next week I guess.
