PDSF Selected Announcements
March 21, 2012
Next Tuesday, 3/27/12, we plan to do maintenance on the eliza file systems from 8:00 to 17:00. This maintenance involves getting GPFS up to the latest version and if all goes well it should not have any impact on your work. However, there is always a (slim) chance that problems could arise, hence this notice. If this is a particularly critical time for you let us know and we'll consider rescheduling.

We need to upgrade pdsf3 with SL6 so we will take it down for maintenance on Tuesday, March 13 2012, from 14:30-16:30 local time. No other resources should be affected.
February 28, 2012
Next Tuesday, March 6, we need to remount /project. We will do this from 8-10am local time. This will only affect batch jobs and interactive use of /project. We will set projectio to 0 the night before so if your jobs specify projectio they will quit starting until after the downtime. If your jobs use /project and don't specify projectio (they should) they will fail when we unmount /project.
On the same day we plan to retire the chos environments sl44 and 32sl44. If you are still using either of them you should switch to sl53. While this has been planned for quite some time if it causes serious problems for you let us know. We do plan to retire it in an easily reversible way just in case of unforeseen problems.

1400-1600 Maintenance on the pdsf4 interactive node. All login sessions on pdsf4 will be terminated on 1400, and logins to PDSF may be slow throughout the maintenance window. Additional non-intrusive maintenance will also be performed elsewhere on PDSF.
January 30, 2012
On Tuesday, 2/7/12, we are planning to do some maintenance on PDSF. If all goes well users should not notice any impact on their work, however, we do want to announce it just in case there are unexpected problems.
One purpose of the maintenance is to add some new filesystem managers. This should help alleviate some of the sluggishness that some of you have noticed recently.
