In ESXI 6.5, I made a huge noob mistake and left an old snapshot that grew in size to the capacity of the datastore of 9TB in size. The datastore was full as a result of this. This prevented me from running the virtual machine and causing it to power off automatically. The datastore does not have any other VMs or files associated with it except for the culprit VM. I was able to increase the capacity of the datastore by about 5TB and am trying to delete the base level snapshot, but googling has stated that deleting snapshots will require free space equal to the size of the snapshot being deleted due to the data from the delta disks being written to the parent disks because of how snapshots work. The deletion process is currently hanging at 0% right now, so my hopes for this to work out is low.
Is there any workaround to free up the space without installing a set of drives to create a larger datastore and migrating the VM to that larger datastore and deleting the snapshots? I currently do not have the ability to do that right now. There are multiple other datastores with data on them that add up to about 4-5TB of space. I don’t have too much knowledge of Vsphere/ESXI. TIA
