I have a 2008 server using a Promise 8350ex Raid 5 using 7 2tb drives. This all works fine right now. So I added another 2tb drive, this migrated just fine into the array.
So I went into disk manager in 2008 to extend the volume like I did with the other 3 drives and they worked fine.
But this time when extending the volume in 2008 I get a message that says "there is not enough space available on the disk(s) to complete this operation"
Not sure why I'm getting this.
