This sticky is to inform the users of an outage starting 3/24/09 regarding the Seti MB Workunits. There is a problem with the Thumper machine and according to Matt's Post- "...don't expect SETI@home to be generating any new work or assimilating anything for a week. We'll at least try to keep Astropulse working during this time, so computers that can run Astropulse will be kept busy." We'll post updates here whenever possible. |

Update from Matt: To help alleviate panic, here's the gist of our general plan: 1. get thumper back up and running with a three-way root mirror. If all goes well, this will be done enough sometime tomorrow (Wednesday), i.e. we'll have a two-way root mirror and let the third one sync up in the background while we bring the system up, then during next week's outage do more drive swapping to install grub/finish the resync on this third drive. Splitting/assimilating will be completely off for all projects until thumper is back up. 2. as soon as thumper is back up (tomorrow?) we can turn splitting/assimilating on for AP and get to work on the pulse table reconfiguration (which we can only do if the system/database is up). The plan (in simplest terms) is: create new database chunks, copy the current pulse table to these new chunks, then drop the old table and rename the new one. We estimate at least 24 hours for that. So if we time things right we may be fully functional before the end of thursday, maybe friday. However considering the lost time this morning and the usual unexpected hurdles that crop up.. that's why I give it a week if only to keep expectations realistic, yet leave room for potential pleasant surprises. - Matt |

Update from Matt: A guiding premise from my days in flight test: plan for the worst, and then all your surprises are pleasant ones. Got my fingers crossed, will be watching and hoping. |

My system got over 100 seti cuda today before it went nuts... I'm gonna find out where you live and hijack your hard drive. All your CUDA are belong to us. Muwahahahaâ„¢ You will be assimilated...bunghole! |

Thanks for the heads up. Posting the info / explanation for the outage will hopefully avoid a lot of the stress, pulling of hair and gnashing of teeth that sometimes acompanies these outages. Hopefully the rebuilds go well and things come back online quickly... weather is getting colder here and I need the warmth of the CPUs running at 100% ;-) Ian |

Oh dear.. This is serious !! With my Q6600, 8800GTS and the 750W PSU all sitting at 99% Idle now they have indeed dropped the ambient temp and it has noticeable slowed down the Fermentation rate of my homebrew. I think I'll name this latest batch 'Thumper' in honour of the ensuing headache. Cheers and Good luck on the fix guys. |

It appears that Matt or someone carelessly started the MB splitter on Lando, rather than the AP splitter. Hope it doesn't foul up the database while it is resyncing. |

One of my crunchers has no work, the other has about 40 MB WU's..... go figure It's downright weird. None of my CUDA machines have received MB WUs, but several of my non-CUDA machines have. Just luck? I guess so. -- Classic 82353 WU / 400979 h |
