Practical GPFS: day 4

[sawyl]

Slightly more successful day today, running through the details of creating new NSDs, setting up GPFS file systems on them and replacing failing discs. After the guys in France resolved some annoying problems with the cluster — GPFS had not been reconfigured following the replacement of one of the servers — we managed to run through a bunch of useful exercises in time to finish by early afternoon.

While it wasn't the best course I've ever been on, the content was good, the instructors were enthusiastic, and I came away knowing more than when I started, but the whole thing was rather let down by the sheer flakiness of lab cluster we were supposed to be using.
