Dear Mark, you said: "Then every virtual disk that is created on that storage type is thin provisioned." Ok ... good to hear that.
So ... Lets suppose I created 5 VMs about 200Gb each on a 1TB space. Im using less than 50% on each VM and now I need to add a 6th VM ? Even Im using thin storage , I will have no free space. What can I do ? a) Should assign minimun capacity during creating time and enlarge later if needed ? b ) Should I look for unused space among existing VMs and reduce the disk ? Please let me know what is your criteria to assign storage to new VM. Leandro.
