I have a 3-node server 2012 Hyper-V cluster with 10 CSV's.
Our main CSV (3.5TB in size holding the majority of our VM's) seems to be increasing in used space even though there have been no VM's added or any changes to it.
A month ago this same CSV ran out of space so all the VM's ground to a halt.
This was most unexpected because, as I said above, there have been no changes to the CSV or the VM's contained within.
During this space outage I moved some VM's around and re-booted one off the nodes. suddenly the CSV free space jumped to 1.7TB free, which is what I expect but strange as what caused the free space to be used up.
now a month later the free space is decreasing again (now down from 1.7TB to 970GB). again there has been no changes to the VM's on the CSV
windirstat puts used pace for the volume at 1.8TB but looking at cluster properties in windows explorer the used space is 2.58TB.
I do not know why this is.
Anyone have any ideas other than reboot the nodes to see if this fixes?
thanks
