I aborted about 15 unstarted jobs in "Jaunty" (current Ubuntu release) and was going to reboot into "Karmic" (beta test -will be released 10/31/2009).

I wanted to leave only 2 or 3 there in Jaunty, and then let the Karmic jobs (about 15 also) run for a while. (I expect that within the week I will be using Karmic soely.)

I don't want to abandon any work. The problem is that when I aborted the Jaunty jobs, BOINC re-downloaded as many or more NEW ones! So what is the best way to do this without hurting SETI@HOME?

Thanks!

If you can start up and use BOINC Manager, go Advanced view->Projects tab->Select Seti and click on the No New Tasks button.

If you use boinccmd (or boinc_cmd, depending on BOINC version), use the following command: boinccmd --project http://setiathome.berkeley.edu nomorework

That will stop downloading more work until you tell it different (which in the Manager is the Allow new tasks button and in boinccmd the same as above, but instead of nomorework you put in allowmorework)

I just re-installaed Jaunty, now on a RAID 0 configuration.
I have Boinc running in my home folder and I simply copied the complete Boinc folder to an external disc, wiped the hard discs clean and re-installed the OS. Then I put the Boinc folder back in my home folder and fired it up. That way I could simply continue with the WU's I was working on. No harm done, no WU missed.

Just to check...

You know that RAID 0 is "RAID stripe". You get the sum of the hdds, up to twice the rate of data throughput (if using 2 hdds), but also complete failure if any one hdd fails.

I would doubt that you need such performance.

Are you really wanting RAID 1 "RAID mirror" so that if one hdd fails, you already have a copy on another hdd to continue working?


Happy crunchin',
