Sure. I was a little iffy about starting tomorrow with short notice anyway. I can do Thursday this week and probably Wednesday next week. ----- Original Message ----- From: "Craig Stacey" <[email protected]> To: "Ken Raffenetti" <[email protected]> Cc: "core-admins" <[email protected]> Sent: Tuesday, October 9, 2012 4:22:46 PM Subject: Re: DRAFT - MCS login node upgrades I'd like to stage them further than a day apart, in case issues arise on the first two.

Any objections to upgrading the MCS login nodes this week? This is the note I'd like to send out.

All,

The 4 MCS login nodes are next to be upgraded to the Ubuntu 12.04 build. These upgrades will take place at 4pm on Wednesday and Thursday this week. Expected downtime is ~30 minutes. Two nodes at a time will be removed from the login round-robin, upgraded, and brought back online. Additionally, user cron jobs will be disabled on the login nodes after the upgrade. Please use one of the dedicated compute nodes instead.

10/10 @ 4pm login1.mcs.anl.gov login2.mcs.anl.gov

10/11 @ 4pm login3.mcs.anl.gov login4.mcs.anl.gov

Let us know if you have any questions.

Thanks, Ken
