Errors Installing Windows Server 2008 R2 SP1 (a.k.a. "How much disk space do I need?!")
A couple of years ago, I wrote a post about issues I encountered deploying Windows Server 2008 Service Pack 2 due to insufficient disk space on various VMs in the the "Jameson Datacenter" (a.k.a. my home lab).
This morning I encountered similar issues when attempting to install Windows Server 2008 R2 SP1 (which I recently approved on my WSUS server). Apparently the disk space requirements have gone up -- again. Significantly.
On the development VM (FOOBAR5) that failed to install the Service Pack, I had 5.5 GB of free space before downloading the 903 MB file from my WSUS server.
Evidently I need 7.4 GB of free space in order to install this latest Service Pack:

Maybe it's time to head over to newegg and see if those terabyte drives are still on sale ;-)
