I installed Windows Server 2008 R2 on a Dell server that has one volume that is a 6 TB RAID 5 array. I created a 120GB install volume and I'm now trying to create a 5 TB data volume. For what ever reason Windows will not allow me to create a new volume out of all of the unalocated space. Windows will allow me to create a new volume out of one 2TB block of unallocated space but not the remaining 3.5 TB block. Tried to post a screen shot but I was blocked.
If I right click on the 1949.85 GB block of space there is the option to create a new volume. If I click on the 3539.5 GB block of space that option is grayed out. If I go into diskpart and try to create a new partition, diskpart says that there is only 1949GBs free on the volume.
I know this process works because I did the exact same thing on another server that we have that is the exact same hardware configuration on which I used the exact same Server 2008 R2 install image.
Any help would be greatly appreciated.
