vSphere 5 Upgrade: PSOD for vSphere 4.1.0 Hosts

I had a customer get ambushed by this last week and wanted to put this out there so hopefully no one else will run into this huge problem.  There is a VMware KB article out regarding the issue, however none of the release notes or upgrade documentation has been updated to reflect the information in the KB article.  Bottom line: DON'T UPGRADE VCENTER TO V5 IF YOU ARE RUNNING VSPHERE 4.1.0 (NO UPDATES) ON YOUR HOSTS! The KB article can be found at the link here: clicky Most of us have read through the upgrade guide for vSphere…

During the customization process for the VM we received the infamous "Windows Setup encountered an internal error while loading…

NFS Large Disk Support in vSphere

I've run into this issue with a couple customers the past couple weeks, and there isn't anything definitive out there that I could find, so I thought I'd write about it.  These customers have a need for disks in a VM larger than the 2TB - 512 bytes that is currently supported.  They have a couple options to get around this limitation but these solutions cause a tad bit more complexity in their environments.   One nugget of knowledge that I confirmed with @VMwareStorage last week was that an NFS volume size…
