Hi,
I wish to dismount the volume on which shadow copy is enabled.But i never get a handle to it because there is always an IO pending on the volume.
Could you please tell me how to do that ?

Programatically, you should use FSCTL_LOCK_VOLUME, FSCTL_DISMOUNT_VOLUME and then FSCTL_UNLOCK_VOLUME to perform a regular dismount. See the link below for more details:

http://msdn.microsoft.com/library/en-us/fileio/base/fsctl_dismount_volume.asp

If you want to perform a forced dismount (i.e. force dismount even if somebody else has a handle opened to the volume) then you should use only FSCTL_DISMOUNT_VOLUME since the lock will fail anyway.

BTW, if you want only a dismount from the command line, then you can use the "FSUTIL VOLUME DISMOUNT C:" command.

Adi,
My Problem is that i am trying to do this in Clustered Environment.When i dismount a volume (to imitate a fail) forcibaly,it becomes unusable during the failover (attching to a different machine).
My volumes are on SCSI disks and VSS is enabled on them.Some how the data gets incosistent and the volume becomes unrecognizable.
Any Pointers ??

How to assign a drive letter or directory to a shadow copy

Praveen Kumar's Blog — Fri, 21 Jan 2005 16:57:00 GMT

In one of my previous posts I mentioned a simple script to copy a file from a shadow copy. This allows you to access files that are opened exclusively by some application.
