Extended an iSCSI mounted disk from 500GB to 750GB in Server 2008 R2 Standard. Saw the larger disk in Disk Management and extended the partition successfully. Ran Chkdsk on the new drive and it shows the correct total, used, and free space on the drive. However, when I open My Computer the drive still shows the same old size.
This is a physical HP server, iscsi drive is from a Netapp.
Things I've tried but didn't work:
1. Diskpart and the extend filesystem command (http://support.microsoft.com/kb/832316)
2. Growing the disk by 1-50GB and re-extending the partition
3. Made funny faces
I've seen this before in Server 2008 R2 on a VM but never on a physical machine. Usually growing the disk and re-extending the parition has worked for me but not in this case.
