Revision as of 09:47, 17 July 2013

The following list of items should ideally be accomplished during spring break. If you are interested in working on a task below, please add your name in the space provided. Items highlighted in red need downtime notification provided to users at least 24 hours in advance of maintenance.

General Notes

Downtime notifications for items highlighted in Red should be posted via Iodine at least 24 hours in advance (but ideally as soon as possible). They should include both a start time and estimated end time. Be generous when estimating end-times :).

In general, a good pattern to follow when updating systems is: Reboot, Update, Reboot again, Verify. This way you are sure that the system is in working order before beginning work. The Verify step is also very important to make sure that you leave systems in working order :).

You should also make sure you have a current backup (If the system is running Guardian, check /root/scripts/backup.log to make sure the last backup is current and successful).

For paired/redundant systems (eg: casey/smith or ns1/ns2), there should be at least 24 hours between the maintenance windows for the two servers to allow time for any subtle problems to surface.
