Hi all,
Currently we have a weird problem with WSB, W2012R2.
The scheduled backup process failed during night time, saying that it is failed to dismount backup image.
We notice that VSS creates "duplicate" volume during backup (vhd file), and when we check disk management console, the duplicated volume is there, not being detached. And when we tried to detach manually, it is being used by process, though we've check the VSS service is stopped, the backup is not running too. We set it offline, and then tried to detach again, still the same.
We tried to use detach vdisk command via diskpart, not successfull too. Vssadmin list writers returns no error.
We have similar backup schedule on another W2012R2 server, same updates state, but there is no problem with vhd detachment.
Please help.
Thanks.
