Again... you have not a 8TB snapshot.... thats your DATA!. All entries above are the snapshots and they are tiny. When this is a VMFS with ESXi as Servers... do you use VM Snapshots from time to time, delete a VM and whats about Veeam or others? If you answer with yes.... when did you run a scsi unmap last time?

Hi Team, I have noticed that the Tier 3 raid has filled up and no more free disk space. [IMAGE] Also noticed the snapshots on my volumes might be bigger than normal size of snapshots? If i delete these huge 8TB snapshots, would this free up some space on the Tier 3? [IMAGE]
