Extending size of system/boot volume c drive
Posted on 2011-10-18
Is there a way to extend the size of the c: drive system volume of windows 2008 standard sp2 server (virtual machine) without using third party utilities. I have increased the provisioned space to "265GB" in Vcenter ESXi 4.1.0, now here's a bit confusing part under disk management of windows it shows only "256Gb", however in local disk c: it says "236GB" total and 5.22Gb free space.
I tried to use diskpart, but I'm getting "diskpart failed to extend volume. Please make sure the volume is valid for extending". Most of the information on the web would tell that system volume/bootdrive cannot be extended when booted or you have to use Gparted and other 3rd part partition utilities in order to extend the volume. Please advise what's the best thing to do for this.
