Yes,you should not have any problems.

if you have full backups before you make any changes, Expansion of partitions is hot plug if you have a modern OS.<br />
<br />
Right Click the Partition/Volume in Disk Management and select Extend/Expand and follow the prompts.

ok cool. Just a very odd setup and was very weird how the C:Drive and D:Drive had the same size allocated/unallocated space.<br />
<br />
Thanks for you help.

One thing I have noticed after after going through the extended wizard. The OS doesn't see the allocated space now. After research, it looks like it is a common issue (see <a href="https://www.jonathanmedd.net/2010/10/windows-server-2008-extend-system-volume-error-the-parameter-is-incorrect.html" rel="ugc">article</a>). I have perform these steps in the artwork and the OS still doesn't recognise the space, even after a clean reboot.<br />
<br />
Any tips on this one?

Hey all,<br />
<br />
I have just taken over a site and one of the critical servers (VM1) is running out of disk space on the C:Drive. Host is running Hyper-V with plenty of space for allocating extra stroage to VM1. The weird thing is that when I look the Disk management within the VM, it shows that there is space that hasn't been allocated. It also has a replica of free unallocated space on the D:Drive which is very odd. <br />
<br />
I would ideally &nbsp;like to just expand the C:Drive - is this safe to do so knowing I have good backups also?

Hey all,

Is it safe to expand the C:Drive within VM if there is unallocated space available?

Virtualization is the act of creating a virtual (rather than actual) version of something, including (but not limited to) a virtual computer hardware platform, operating system (OS), storage device, or computer network resources. Virtualization is usually the creation of a system that executes separate from the underlying hardware resources, or the creation of an entire desktop for systems located elsewhere, similar to thin clients.

Virtualization

The term "Backup" means the methods and processes involved to copy computer data (system data as well as application data) to media other than the ones where the data originally live (disk, tape, optical, cloud). "Restore" in turn means the methods and processes involved in data recovery, i. e., bringing back copied computer data to their original location. Backup/Restore primarily serves as a means of protection against data loss, be it due to disaster, corruption or sabotage. It can also be used for recovering data from an earlier point in time and even for cloning machines or applications. There is a wide variety of backup/restore software available, from expensive commercial products to free or open source tools.

Storage Software

Hyper-V is a native hypervisor; it can create virtual machines on x86-64 systems and supersedes Windows Virtual PC as the hardware virtualization component of the client editions of Windows NT. A server computer running Hyper-V can be configured to expose individual virtual machines to one or more networks. Hyper-V Server supports remote access via Remote Desktop Connection. Administration and configuration of the host OS and the guest virtual machines is generally done over the network.
