Remove physical hard drive from VM in Hyper-V In case you have multiple physical drives that you want to add to your VM and you are not able to add them under current SCSI Controller, create a new SCSI Controller and add hard drives under new SCSI Controller. Now VM sees Samsung SSD 960 as a drive on it. You can now see that the third drive is Physical drive for my VM.Īfter you turn on VM, again go to Control Panel… Disk Management inside VM.

New Hard Drive will appear under SCSI Controller, select it, and select Physical hard diskĪlthough I have two unformatted and offline physical drives. Select SCSI Controller | click on Hard Drive | select Add Open Hyper-V Manager, shut down VM you wish to add disk to (it is the safest way) and select Settings of the VM Installed Hyper-V, available hard drive in offline state, and a VM to add disk to.ĭisks you wish to add need to be in offline stateĬontrol Panel | Administrative Tools | Computer Management | select Disk Management | disk you wish to add should be Offline. If you have some data on the disk you wish to attach/detach to VM, make sure you have valid backups before you proceed. You need HBA or SATA/NVMe directly from your motherboard (without RAID settings)Īlso, in my experience USB drives will also now work with this. This probably will not work if you have RAID controller in charge of your disks.

In this short guide, I will show you how to add physical disk to the VM inside Hyper-V on Windows Server 2019. You can do that inside Hyper-V, assuming you don’t have RAID controller in the way. It is a common occurrence that in a virtualized environment, we encounter such issue quite often and this is a handy way to add that breathing space to the virtualized OS.There are times when you have to add physical disk directly to the VM (like Storage Spaces Direct for example).

Then assign the partition number you wish based on your existing partition numbering. After this enter ‘n’ in the next line for creating new partition.

Expand the disk capacity from settings with your desired value. So, we need to mount the expanded partition and merge it with the partition that requires expansion.Ģ. This is because when VM HDD is expanded from the hypervisor, the additional space in only added to the end of the last logical partition (i.e. SWAP.Īnd if you think that expanding the HDD from hypervisor will solve this, then you are wrong. There are min three partitions created 1. In a virtualized environment when a LINUX OS created the VM contained one VHD. In this article, I would like to discuss how to incorporate the extra space into the existing Linux partition. This requires a simple tweak inside the Linux Operating System to add the extra space to the partition that needs it. However, the space that can be added to the VM Hard Disc will not necessarily increase space of the Linux root drive because when a Virtual Machine Hard disc is expanded, space is only added to the end of the logical partitions. In a virtualized environment you have a LINUX based Virtual Machine and the root drive has run out of space in an existing partition inside a single VM hard disc.
