I'm running Nexenta Enteprise version on a 64-bit Intel system. I have a 3 TB data drive (not booting from this drive) and when I insert it into the open hard drive bay, the Nexenta Web GUI recognizes the drive, but only as 2 TB.
After reading these two links, I decided to reconfigure the 3 TB HD as GPT. I connected the HD via esata to my laptop and could only see about 746 GB. I then used Gparted to reconfigure the drive as GPT. I could then see all 3 TB.
However, after putting the data drives into my NAS running Nexenta, it still recognizes only 2 TB. How can this be resolved so that it sees the 3 TB?
