DRAFT - MCS login node upgrades

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
