We use it here on our FAS270c. CPU utilization on our filer has gone redline since the upgrade. The problem is caused by a background wafl free-space reclamation process that takes place after snapshot deletion. In previous releases, this process did not run with every snapshot delete, but now it runs at EVERY snapshot. The process takes hours to complete. As I understand it, this bug is also present in OnTap 7.0.5, and "it is being worked on" (so I am told). I also understand that this is not an issue for filers with more memory than the 270 (that would be pretty much all of them, right?)
Fortunately, since this is a background process it is not affecting CIFS performance. Unfortunately, it is really messing with our backup and restore operations.
Other than that, I am quite happy with 7.2... it contains many bug fixes that we needed. One nice improvement is that my SSH sessions with the filer have stopped crashing out.

So what's the word on 7.2 ready for install or still hold off?
