1. Announcements
   • First meeting of the year!
   • Spring run starts in about 2 weeks.
   • Update on Lustre system: [info from Mark Ito]: Five disk servers (out of about 50-100) failed on Dec 31. Two have been recovered. Three remain down and Intel engineers are working to get them back. Files are spread over the entire disk system, so the impact of the proportionally larger than might be expected. The files themselves are thought to be ok so fixing the servers should restore the files. Unfortunately the fixes are labor intensive and will possibly take weeks.
