VMware ESXi v4.1 thin provisioning
Posted on 2014-01-12
I have a datastore that is only showing 1.6 GBs of space available. If I move data off of this drive it won't show the space being free. I've opened up a thread in the past and it seems to be a known that space will not be released unless I move the disk to a different datastore or move the VM completely to a different host.. But.. If I move data off of this thin provision disk will it dismount if ESXi is reporting to vsphere it being low or will it truly know how much space is available? The reality is that I have 1.6 GBs free but I'm about to move 70 GBs to another datastore.. But.. Will it void dropping since I moved 70 GBs or is it going to drop based on what's being reported?
