Lots of VMware / Windows administrators can extend virtual disks on-the-fly in a few seconds, but what is the easiest way to shrink a / the (OS) volume?
In this post I’ll show a (simple) method how-to shrink the system disk size from a virtual machine from 60 to 40 GB.
In all cases, confirm the following before shrink the size of the virtual disk:
- All snapshots have been removed;
- The virtual machine is powered off;
Install VMware Converter and connect you’re vCenter server running that specific virtual machine
- Start the VMware Converter by clicking “Convert machine”;
- Select source server (virtual machine on vSphere host);
- Select destination server (same vSphere host, new VM name);
- Select target datastore;- Options: select “Data to copy” and press Edit;
^ you can see the source volume (60 GB) and used space (23,45 GB)
