Unable to delete ReadOnly ReFS volume on Windows 2012 Server

Hi All

I have a issue regarding read-only ReFS volume in windows Server 2012 which is mentioned below:

1. Create a ReFS volume from diskmgmt let's say V1(H:)

2.make this volume readonly by following diskpart command
DISKPART> attributes volume set readonly

Volume attributes set successfully.

DISKPART> attributes volume
Read-only              : Yes
Hidden                 : No
No Default Drive Letter: No
Shadow Copy            : No

3. when we try to delete this readonly volume, it gives error that volume is in use as mentioned below:
DISKPART> delete volume

Virtual Disk Service error:
The device is in use.

The selected volume or partition is in use.
To continue with the operation use the OVERRIDE parameter.

3. Although we can delete volume force-fully but the same case is working properly for NTFS.

So the qustions are that:
1. Is this a known issue in windows 2012?
2. Is it ok to always destroys ReFS volume forcefully in windows 2012?
3. If it's a known issue, Is Microsoft planning to provide some fix for this in windows 201

Hi Nilesh,

I tried and got the same result as yours.

Meanwhile the behavior did not occur when I try the same steps on Windows Server 2012 R2 system.

Personally I think Override parameter will not affect the disks but if you feel uncomfortable with keep using Override to delete a volume, at least we can remove the Readonly attribute manually with "attributes volume clear readonly" in Diskpart. After that the volume could be removed successfully.

Hi Nilesh,

No, just my personal opinion. I cannot confirm if it is an issue in Windows Server 2012, or it is an improvement if Windows 2012 R2. 

But "clear readonly" will work and avoid to "force-delete" the volume.
