This window will be used to switch back to using NFS version 3 on all desktops and compute nodes. The reason for this is that we continue to experience reliability problems with NFS version 4. Any processes running on any compute nodes should be stopped, and any Linux desktop sessions using /auton home directories should be logged out after you are done on Thursday. Do not shutdown your Linux desktop, only log out. Neill Lab machines will not be affected unless you are accessing /auton space. -- Michael J.

For faculty/staff, please log out of, but do not shut down your Linux desktops. After the downtime window ends at 8A, you should reboot your machine. Users on neill* machines using only /neill space will not be affected by this downtime. -- Michael J.

Staff using Linux desktops should reboot before logging into their systems. The /auton/data is currently offline. Data is in process of being copied, and is noticeably slowing access to the file server. Please be patient while the data is copied. You'll receive notification when the /auton/data directory is back online.

Message-ID: <4B9392DA.6050203@cs.cmu.edu> Hi Lab, Someone almost just took down LOP1 by overloading it. I am taking the opportunity to stress the importance of keeping LOP1 free of jobs. LOP1's primary job is to be the access node for the rest of the machines. Here are some valid uses that fall under that category: 1) SSHing to LOP1 in order to SSH to another compute node. 2) Using LOP1 to scp data into the /auton or /neill space. 3) Using it for SSH tunneling CVS (most of you do this without even knowing it.) 4) Running only very light duty, low memory scripts and short running processes. WHY? 1) Everyone is accessing all computing resources through LOP1 (or LOP2 as a backup, but mostly LOP1.) 2) Overloading LOP1 disconnects everyone from the cluster! 3) Any processes or sessions that people forgot to run in screen will be lost on all machines! 4) Many people tunnel X11 apps on other nodes over ssh through LOP1. You will, without fail, cause that person's program to die. 5) If you run big jobs on LOP1 and I see them, I kill them.

If you had anything running there, please check your jobs. Also, LOQ1 is back in service. LOP3 is offline.

Im going to a conference and by far the best thing that I have found is a box that cannot fit in the poster. So if anybody have one of this tubes to carry a poster can I borrow it for this week?. I will really appreciate it. By the way Im leaving tomorrow in the afternoon to the conference, Thanks, -- Julian. -------------- next part -------------- An HTML attachment was scrubbed...
