Hi Charlie, Most of them don't fit well to the RT system. Some of them are not trivial. The main thing we need to do is OS/ZFS upgrade to handle failed SATA drives since the failure during STEP09 was the second in a month on the same (replaced) disk. We had planned last week but had to cancel because of the current cosmic data run. We have put in a method to control batch jobs, and are looking at other ideas. This will be long term planning/development for xrootd (which Andy will outline on Wed's OSG storage meeting at Fermi lab). We also did some ZFS turning. We did that on half of our storage in order to see the effectiveness of those changes.
