I'm using a 4 node Hyper-V R2 cluster with SCVMM R2 and multiple CSV's (700 GB each) and I was wondering what are the requirements (or best practices) regarding to the amount of disk space to keep free on a CSV volume.
I understand that actions like mounting ISO's to VM's (without sharing them), allocating more memory to a VM, taking snapshots of a VM and adding or extending VHD's result in an increase of disk space used, but I cannot find any official statement or guideline from Microsoft about this subject.
Any thoughts on this?
