Extended volume on server but windows explorer will not show it

I am running windows server 2008. We extended the drive on our exchange DB volume. However, after using disk management to extend the drive, the space shows extended in disk management but the capacity value shows the original size. Also in Windows explorer the original size is shown.

This article describes the exact same symptoms http://support.microsoft.com/default.aspx?scid=kb;EN-US;832316, however i am a bit cautious on running diskpart and the extend filesystem command on the volume that hold our exchange DB. Is this safe to run during the day while everyone is using it?

-Thanks

What brand of server do you have, some servers will not allow you to extend the partition without memory on your RAID controller.  I have run into this on several HP servers.
 
You will definitely need to schedule downtime though to handle this.
My recommendation is to call your PC Manufacturer support.

In my experience, it is allways better to ask the manufacturer even when you know what you are doing.

But, as an alternative, you can use Acronis Disk Director in cases where it is not supported in Windows (such as the OS drive) to extend the partition.  

One last suggestion.
If you have your Exchange database stored on your C Drive, you may consider adding a good bit of storage (seperate volume) as D Drive or whatever.  Moving/Spliting/Migrating mailboxes over to it.

I like having two or three mailboxes on my Exchange server if I have a large number of users.  If one mailbox should have problems or whatever, I still have users functioning.

Just a thought.

It is a virtual machine on an ESXi host. The mail DB is on a separate drive than the C drive.

I used diskpart many times against VMs and it was totally safe.

Are the disks clustered?

After reviewing your question again...

Is this safe to run during the day while everyone is using it?

I seem to have overcomplicated my response.
I apologize.

You shouldn't have any problems running it during the day.
It does not require a reboot in Server 2008

I googled real quick an article that confirms the "no reboot" in server 2008
Several people on this agree as well
