CSV - System Volume Information Problem

Hi,

Not sure if this is the correct place to ask my question...

We are having an issue with the System Volume Information on one of our Cluster Shared Volumes growing to a large size.
It currently sits at 598GB. 

We have two hosts - Three volumes, C:\ClusterStorage\ - Volume1 - Volume2 and Volume3.

The issue only appears to be happening on Volume2 in the System Volume Information folder and not sure what's causing it.

I have checked Shadow Copies on both hosts and all are disabled.

We run a daily windows backup on each host to separate USB drives also.

Thanks,
Adam
