File Archiving on Isilon - Stubbing did not happen

Hi, we are testing the file archiving on an isilon and the archiving itself works fine but it does not create any stubs.

Error code: [72:106]
Description: Warning: Job completed partially successful: Stubbing did not happen

We tested the same on a Netapp share where archiving and stubbing works fine.

Does anyone have had any similar issues?

Thanks
