One of servers running 2008 x64 is our main storage server for media etc.
The server has an Adaptec 3405 controller running Raid5.
Originally there were 3 x 1TB drives in the container giving us approx 2TB of storage after parity.
Space became an issue so a 4th 1TB drive was added and Raid optimized.
Space again became issue so the plan was to one at a time replace the 1TB drives with 2TB drives.
Each drive was replaced in order with Raid optimizing in between of course. We now have 4 x 2TB drives fully optimized.
Windows 2008 still only sees 2TB!
So I know this at the controller level. I have been trying everything in the Adaptec SM to expand the space. You can see a graph that shows that only about 650G of each drive is used..the rest is empty space accross each drive equally.
I thought we could get the controller to see all 8 TB of space, reconfig itself so that we had 6TB of storage with 2TB for parity.
Then go into win28 disk management and expand the drive so it grabs the additonal space.
