garbage collection
Hello,
Our customer has a centera with the latest version of centrastar. They have purchased a basic license.
I have created a test pool where we have placed few pdfs. About 20Mb. These files came in from EMC Content Server with Documentum Administrator Now, I have went in and deleted these files thru my application. It has been 2-3 days and those files still show in this file pool. Same amount of c-clips and size of the pool stay.
How can I really make sure that blobs with unreferenced ca's in my application get deleted off of the Centera?

Thanks for that!
Just to make sure, I got it right: if I delete a clip with c-del, the data actually does get deleted. It's just the reflection which remains (not sure what a "reflection" means in that term - but will find that out)
Correct?

Hi Reto
Garbage Collection frees up the space of the blobs referenced by the clips. If you delete a clip with c-del the reflection remains. This is what allows you to find it with c-list -deleted_only. These reflections are not deleted within Centera and you'll always be able to find them.
After a Garbage Collection run you should see more available capacity in CenteraViewer CLI sho capacity availability. Protected Userdate will decrease in turn.
I hope this helps.

Hi Reto
You are correct. A reflection is a copy of the CDF with the information of the IP address and the time the deletion happened. In case of privileged delete the reason string is added.

I actually have a similar issue:
I deleted some clips with c-del and they are not shown by c-list anymore - unless I use the "-deleted_only" options.
As far as I understand, a clip stays around even it is deleted for a while. But after a Garbage Collect it should be removed.
However, in my case it remains. Even after I ran a Garbage Collect, the clip(s) are still shown in c-list xxxxxx -deleted_only.
Is my understanding how garbage collect works wrong?
