C:\ low on space with 30GB free on adjacent partition

GlenTech 486 Reputation points

I have an old 2012 R2 box that’s consistently running low on disk space on C:. I’ve shrunk another partition by 30GB to allocate to C:\ but I know it needs to be contiguous space in order to extend which is why in disk management the option is grayed out but in the Sever Manager GUI under Files and Storage > volumes > disks, when I select the C:\ it does give the option to extend and it sees the 30GB.

In the past I’ve has to use a boot disk like gparted to move the free space over but it seems like the server manager will allow it, but I haven’t used this method before. Will that work or will it error out?

    Hi @GlenTech ,

    To extend the volume with non-contiguous space, the disk has to be converted to dynamic. I tried this operation in my lab and it failed as expected.
