The virtual machine Sunjammer (running multiple services for the domains sugarlabs.org, ole.org, olenepal.org and codewiz.org) will go offline for relocation this evening. The downtime is projected to last 15-30 minutes, but it may last longer in case of unexpected issues. Our new XEN host, cloud9.fsf.org, has faster processors, twice as much memory, a faster RAID1 array and generally better hardware. The migration should mitigate the longstanding server overloading issue caused by intense traffic on http://activities.sugarlabs.org during weekdays. A previous attempt to move Sunjammer on this machine failed because of unreliable configuration of the memory banks. This time, we believe we have corrected the problem and verified this by running an extensive test cycle with memtest86+. Thanks to Daniel J. Clark of the FSF for all the time he has dedicated to support Sugar Labs. === Addenda: Future plans for Sunjammer === Following this operation, I'm planning to split out a few critical services from Sunjammer to a twin VM called "beamrider", to be hosted on treehouse.sugarlabs.org, a new 2U box with 64GB of RAM kindly offered to us by Stefan "dogi" Unterhauser. I've completed some nasty burn-in tests to verify the general stability of treehouse and I'm currently still working to setup backups and monitoring. Meanwhile, I'm also trying to figure out why virt-install is borked on Jaunty. It works decently on both Karmic and Fedora 11 (well, it's barely usable on those too). Hopefully one day libvirtd and its associated tools will become so mature that I won't have to grep the sources for error messages every time I want to do something as easy as net-installing a new VM. Until then, thank god it's free software. -- // Bernie Innocenti - http://codewiz.org/ \X/ Sugar Labs - http://sugarlabs.org/ _______________________________________________ IAEP -- It's An Education Project (not a laptop project!)
