LHC@home

Hi,

I got the following error every time when I try to run BOINC the second time, when ATLAS LHC@Home running.

BOINC ownership or permissions are not set properly; please reinstall BOINC.
(Error code -1202 at /Library/Application Support/BOINC Data/projects/virtualbox)

Reinstall solves the issue, but I would prefer to able just lunch it. :)

I'm on Mac, BOINC version 8.0.2.
I tried to give permission on the mentioned folder to all, but it didn't solved the issue.

Thanks for your help!

I have been seeing this also.

After some puttering around, I noticed that the directory "projects/virtualbox" is the only directory in the projects directory which isn't actually a BOINC project, which is suspicious -- I would guess that something in the LHC setup program (running the "strings" program on lhcathome.cern.ch_lhcathome/vboxwrapper_26206_x86_64-apple-darwin coughs up the string "/../virtualbox", which I found interesting).

Re-running the BOINC installer causes projects/virtualbox to be removed. Starting up BOINC then re-creates the directory, so apparently removing it is harmless -- and after quitting BOINC and removing that directory, the BOINC manager was able to start normally and LHC resumed without complaint (re-creating the directory). So that's a slightly faster workaround than repeating the installer for BOINC, but not much less annoying.

The directory lhcathome.cern.ch_lhcathome also has a "vboxwrapper_26207b_x86_64-apple-darwin", which does not contain the string "/../virtualbox". The number in the filename is greater, but the creation date (on my Mac) is 5 days earlier. Maybe different applications use different wrappers?

Anyway, it would appear that the wrapper for either ATLAS in particular or LHC in general is creating that virtualbox directory in the wrong place, annoying BOINC's permission verification.

Thank you. I hacked around that folder and

sudo chown boinc_master:boinc_project virtualbox

solved the issue.

Hmm... I celebrated too early. Worked for some restart, but now stopped working again, don't know why.

This issue is in the used VBoxWrapper. There is an old version used.
