What's the problem here? That on a large SunRay server the likelihood of users running 'sync' at any given time is very high, and that this affects performance? Or is it that one user can hog I/O resources? If the former, then make sync/lockfs -f take their time; make it a resource control, set the minimum for mere mortal users to five seconds (think ZFS :) and declare victory. If the latter, then perhaps we need better per-user I/O resource controls. Nico --
