LHC@home

Hello everyone,

Before talking about my problem, I wanted to tell you that I just joined the community. I'm just starting out and my problem has probably already been solved, but I don't have anything to say about it.

My Boinc-client is running on a Debian 12 in LXC and the connection is fine, but it can't mv the files, so my tasks end up with a miscalculation...

Here are the boinc-client service logs:

Have you ever seen this problem?

I think the problem lies in the bash script that's downloaded with the task and that's launched when the task is started... At the end, it performs a directory cleanup, but it has to do it too early, so it can't find the directory...

Thanks for your help and have a nice weekend.

Have you checked Yeti's checklist, or David Cameron's message to use Atlas-Tasks?
You find them in the folders.

Your computer runs ATLAS native which requires a local CVMFS client to be installed and correctly configured.

That's what your early logs state:

[2024-01-26 22:35:03] ** It looks like CVMFS is not installed on this host.

More recent logs state this:

[2024-01-28 13:23:34] Checking for CVMFS
[2024-01-28 13:23:34] Probing /cvmfs/atlas.cern.ch... Failed!
[2024-01-28 13:23:34] Probing /cvmfs/atlas-condb.cern.ch... Failed!

Stop requesting fresh work until you solved the CVMFS misconfiguration.
Otherwise all tasks will fail.
