I'm trying to expand a disk on my Windows 2008 R2 Std server, The current disk size is 15TB.
When I run the extend command I get the following error:
Virtual Disk Service error:
The volume cannot be extended because the number of clusters will exceed the maximum number of clusters supported by the file system.
The array is Raid6 with 15 x 2TB disks (2 hot spares)
The disk is a Basic GPT,
Bytes Per Sector : 512
Bytes Per Cluster : 4096
Bytes Per FileRecord Segment : 1024
Is there way to get round this without having to format the drive?
