My boxes are already crunching fine (I have got several LHC-WUs), but I still see following messages:

20/07/2007 12:40:39|lhcathome|You used the wrong URL for this project
20/07/2007 12:40:39|lhcathome|The correct URL is http://lhcathome.cern.ch/lhcathome/
20/07/2007 12:40:39|lhcathome|Using the wrong URL can cause problems in some cases.
20/07/2007 12:40:39|lhcathome|When convenient, detach this project, then reattach to http://lhcathome.cern.ch/lhcathome/

I thaught, this would repair itself, but it is still the same. I was hoping, that it would repair if the client got one or more WUs, but the messages are still there.

So, here is the question again: Do I really need to detach / reattach all my boxes ?




Supporting BOINC, a great concept !

quick answer: YES... do it while there's still work

you can merge your new host id with the old ones afterwards.

wait.. don't detach if you have lhc wus crunching right now
!
sorry....

As others pointed out, detaching/reattaching plus subsequent merging is one way of solving the problem. You end up with the newest host ID and you lose track of when that host originally joined the project. Also, there is probably some risk of not being able to merge and therefore a risk of losing the individual stats for that host. I'm not really sure how significant that risk is as I haven't taken that path and tried it out.

Here is what I did which worked for me:-


  • Stop BOINC
  • Correct the string for the master_url tag in three files, account_lhc*.xml, client_state.xml, statistics_lhc*.xml
  • In the projects folder, change the name of the lhc subdir to lhcathome.cern.ch_lhcathome
  • In the main BOINC folder make a similar name change to 5 files, account_lhc*.xml, master_lhc*.xml, sched_reply_lhc*.xml, sched_request_lhc*.xml and statistics_lhc*.xml
  • Restart BOINC



Some of the filename changes are cosmetic, ie to not have new files created with the old ones still hanging around. The name change for the project subdir also prevents an unnecessary new copy of all the executables from being downloaded.

All in all, it just takes a couple of minutes and I get to keep my old host ID, and my individual host stats on the statistics tab of Boinc Manager.


Cheers,
Gary.

I'm a BAM!-User, so I had not to do anything at all. :)

BAM! automatically deattached and reattached with the new URL. And I even kept my old host-id. :D
