Raid Storage Expansion problem
Posted on 2010-08-26
I have an immediate issue we need assitance with.
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.
Wont allow !
Need help fast I am out space
