Can I extend C:\ drive in Windows Server 2008 R2 ? I know how to do this with vCenter to extend the VM for C Drive vmdk and Disk Management/rescan/extend in Windows).
My concern is not how to do it but whether this is a risk as I cannot cause a loss of service or risk to my SQL Server/Sharepoint database.
I've done this on a cluster by extending the inactive SQL Server node, then failing over and extending the other inactive node. Don't know if that's required to do while inactive only because of cluster, or if no SQL Server DB VMs should have any disks extended while running SQL Server. Or is this just for data disks and absolutely fine for C Drive?
Points generously awarded for real-world assurances from your experiences.
