Does copy to/from Isilon cluster trigger open/close events
We have Symantec ICAP Engines configured for our Isilon cluster and every time a file is opened from the cluster, user feels a delay. Which is expected as we have configured the AV settings to scan on open and close.
What we would like to know:
1. Does a file open event is triggered when a file copied out of the cluster? This can help us to understand if there is a delay in copy performance.
2. Similarly. Does a file close event is triggered when a file is copied to the cluster? This will help us decide is we have to continue keeping the scan on open option enabled, if we have completed a full offline manual scan of the cluster.
This is primarily focused on Isilon read performance.
