SVS Layer Creation
Hey,
We recently started using SVS where I work, and have been having issues. We're a college campus and manage about 700 computers that students and faculty can log on to use whenever, with domain log on set up. We've been running into a huge problem with slooooow domain log on since switching to SVS, I'm talking around 5 minutes on our oldest architecture of machines. We think that the problem is that every time a person logs in certain profile information is saved into the writable portion of the SVS layers, so as time goes on the logins take more and more time as more and more people have logged onto a specific machine. Resetting the layers seems to resolve this slow log on for a time, but it just builds up again. We have been toying with the idea of making a logout hook that resets all the layers, but this would make logging out take an extra couple minutes. Basically I'm wondering if our guesses are right, that the layers are getting this profile info, and if there is a way to make layers not capture this info. I have been trying to use global excludes to do this, but the way I seem to be understanding global excludes is that they stop the layer from capturing changes to the selected areas... I could and probably am way off base >.<
Any help would be greatly appreciated, and if anyone has a similar set up that had a similar problem I'd love to know how you fixed it.
Thanks,
Victor
Help given
Victor,
First of all create a Global excludes for c:\documents and settings. It will create a exclusion [PROFILESDIR]
Second step: The Logon hook is activating and importing applications during logon. The logon seems to hang untill everything is finished. I have rewritten the logon hook. In my version it is doing it's job on the background, but the userlogon finishes. The user will not notice the delay except for a period of 3 seconds.
I will see if this logon hook can be distributed so you can test it.
What you need is a profile management system. You can do this by switching to hybrid profiles with Flexprofile. This is a free but technical heavy solution.
You can take a look at Scense. This manages profiles, and does a great job at schools.
You can switch to Res Powerfuse. Send a PM to ademeijer. He knows this exactly.
If you are located in Europe, i can help you also further.

The way I've been coming to
The way I've been coming to understand Excludes is that they make it so that when you do the svscmd reset command the excluded locations are ignored so data is not lost. What we need is a way to make a layer with essentially no writable layer, just a read only layer... is this possible?
Thanks,
Victor
Understanding excludes
Victor, Global excludes do not mean that with a reset the locations are excluded, but means that the locations are not inside the layer.
If you create globalexcludes for your whole computer except for c:/windows and c: program files, then oonly the application is inside the layer. In this way the read/write layer exists, but will stay very empty.
I would not recommend this, but it is what you actually asked.
