Hi,
My CSVs (iSCSI SAN volumes) are filling up, but I can't see what is taking the space. I have a server 2012 cluster with 4x 3TB CSVs on an iSCSI SAN. One of the CSVs has only 250GB free according to the properties of the disk in Cluster manager, however the total amount of disk used by my VMs is 1.8TB, so I have almost a TB of space being used but I can't see what by.
I backup the VMs using DPM 2012 SP1 so I think VSS may be to blame (no VSS hardware providers install, using the Microsoft VSS provider), but running a vssadmin list shadowstorage doesn't return any info about whats in use by VSS
vssadmin list shadowstorage
vssadmin 1.1 - Volume Shadow Copy Service administrative command-line tool

No items found that satisfy the query.
Are there any other things I can do to see what is eating the space and to recover it?
Cheers,
James
