Snapshot Question

Jump to solution

I should know this but I'll ask anyway...

I have a View desktop base image with the Gold snap.  I created another snap with the updated View agent.  If I delete that latest snap, will all my changes be applied to the base image or to the Gold snap?

When you delete a snapshot, the changes will be committed into the parent disk/vmdk. In your case changes done after taking the second snapshot (your-000002.vmdk) will be committed to the snapshot-disk (your-000001.vmdk) of your Gold-Snap. This means there are no changes in your Gold Image (your.vmdk), because this is the vmdk from before you took the Gold-Snap.

Maybe a small picture will explain this better (not nice but maybe helpful Smiley Wink)

Thanks.  I created a new snap of my gold to test the new view agent.  I created a new Pool using the base Gold image, but then selected the snapshot with my updates (new agent, windows updates, etc) but the new desktop has none of my changes. 

It doesn't use the new snap as a base?

You have to create a snapshot after the installation of any additional software and point to this snapshot in View. That should do the trick.

Still didn't work.  Keep in mind that the base still doesn't have the new agent, just the latest snap of it.  Should this actually work?

What exactly did you do after you created the latest snapshot (after the new agent and updates have been installed)? Did you create a new pool, selecting this snapshot rather than the Gold snap or did you recompose the existing pool with the new snapshot configured?

I created a new pool using base image with the old agent.  Then I seletected the new snap that has the latest agent.

Hmmm, so my new test worked.  I guess I wasn't doing something correctly before...?

I would venture a guess that you named the snapshot the same as the original snapshot. When you went to put it in play, you saw the same name as the base image and left it, so a new relica was never made. When you went through again and walked through the steps and set the snapshot, it created the new replica and did what you want.

Just my thought upon reading it.
