Hi,
We have fileserver cluster of windows server 2008 with sp2. We have 
installed DPM 2010 agents on both fileserver and DPM detected them as cluster 
nodes. 

We tried to set one test job to backup one folder of 5gb from clustered 
volume. At "Review disk allocation"  we got "Total data size: 4,604 GB" which 
is the size of the whole volume and so we are getting below error in same 
wizard step.

"There is insufficient free space in the storage pool for this protection 
group." 
We have 1.9TB space available to SAN connected to DPM server.

Do we need to configure agent on fileserver cluster..
-Tejas

        Even when you select a folder in a volume, DPM calculates the space 
required based on how much the folder size can grow. This will be equal to 
the volume free space. To change the allocation sizes, click on Modify 
button and then click the calculate link, it will select the minimum size 
required to protect the folder. Hope this helps you understand why such 
defaults are used and at the same time gives you the flexibility to modify 
those values.

Thanks,
Praveen D [MSFT]
