This isn't specific to Ubuntu, but the VM's in question are ubuntu 18.04.4 LTS so I figure folks here likely could help.
I have an ESXi homelab and I very much accidentally assigned way to much disc space to some VM's that don't need it. I do have Veeam running on a Windows LTSC VM in case things go south, but I am not even sure where to start. The VM's in question are Ubuntu 18.04.4 LTS and they are running under ESXi 6.5 U2 and are thick provisioned. I am just not sure the best way to go about this at all. I am not even sure where to start.
My Veeam backup of one example is 5 GB but I gave the VM 20 GB (its a VM that won't really grow for any appreciable reason on its own, and 10 GB would be PLENTY). Obviously, 10 GB isn't a huge issue, but I have a handful of VM's I could trim down similarly, and ~40 GB is non-trivial. Sure, another SSD for a second datastore is also ~50 bucks which is trivial, but still, homelabs are here for us to learn on, so I figure why not figure out how to do this....
Any help would be great!
