I have installed 11g R2 Grid Infrastructure followed by database software only installation. I have not created any database yet.
When I open asmca->diskgroup, I can see the diskgroup which I have created during grid installation. When I select that diskgroup->View Serviced Databases, what is the expected result? I am assuming it to be empty. But, in my case, I am seeing my Cluster name( SCAN name) as database name and used space is .26GB. Can somebody clarify on this. Thanks in advance.

That is the Oracle Cluster Registry (OCR) where information about clusterware components is stored.

Its size is 256 MB, or 0.26GB, you can check this with ocrcheck:
