The lab wide power outage more or less went along with any major problems. We powered down all the systems yesterday afternoon (and unplugged most of them to be safe) and brought them back on line this morning. Right off the bat there were no failed disks or broken RAIDs or anything like that except for Eric's hydrogen survey system which was giving him hell for a couple hours due to one partition that needed a ridiculously long fsck. But there were still funny little gremlins like mangled mount permissions, or various headaches caused by NetworkManager. I swear this program or whatever it is only exists to create random problems for network managers to solve and thus protect their jobs (hence the name of the software package itself). We try to remove this package from every system but sometimes it comes creeping back as a dependency from a seemingly unrelated update. Yeah, we have it excluded in our yum.conf's but that line was missing on two machines, and those were the two having problems upon reboot this morning. Anyway... as much as a pain this was for everyone it completely obscured a problem down on campus which would have caused an hour long network outage last night. But since we were already completely off line, no harm no foul. - Matt -- BOINC/SETI@home network/web/science/development person -- "Any idiot can have a good idea.

Glad everything went well Matt. One question many are wondering about though, it seems all our pendings are falling as no new pendings are showing up on the pendings page. The old pendings are working right as they get validated but no new ones showing up. Any idea what's up with that? PROUD MEMBER OF Team Starfire World BOINC |

Matt, Someone still needs to run the scripts to bring Beta online. |

Matt, Someone still needs to run the scripts to bring Beta online. I think Eric is messing around with some stuff - he asked that the beta project remain offline as we brought everything else up. - Matt -- BOINC/SETI@home network/web/science/development person -- "Any idiot can have a good idea.

It looks like someone needs to load more tapes into the splitters and wake up the Astropulse splitters. The SETI@home Enhanced multibeam splitters are completely out of work to do, and the Astropulse splitters are not running according to the server status page. |

This is happening automatically in the background, but there is some delay (remember that each file has to go through 3-4 hours of radar "cleansing" first). - Matt -- BOINC/SETI@home network/web/science/development person -- "Any idiot can have a good idea.

Bringing systems back online. It's just like unwrapping packages at Christmas time. You're never sure if it is going to be a present or a lump of coal. :) Thanks for keeping us updated. Gold Stars all around. |
