Seagate ST31500341AS 1.5TB

Actually, there's a 3rd option which you probably won't want to do - blast it and start over, losing all your data on the drives. Backup first, reconfigure, restore.

What you've done is broken the array. You've expanded to 4 drives by placing the additional 2 drives in the two empty slots. You should have replaced the 750GB drives 1 at a time. You cannot move from 4 drives to 3. You have two options: 1) leave the 750GB in and do without the additional space the 1.5TB drives give you. 2) buy an extra 1.5TB to replace the 750GB you've taken out.

I added two in the two empty slots and it went for hours to initialize them. I then took out one of the 750GB drives and replaced it with my third 1.5TB. All was according to what I expected. The Volume Settings page showed 1 698 GB Seagate with 694 GB allocated and 3 1397GB Seagates with 694 GB allocated. All my data was there. I then removed the 1 smaller drive (in slot 1) and after rebooting several times it's still not understanding that it's supposed to expand. It shows: Disk space: 101 GB (4%) of 2076 GB used Additional 5 GB reserved for snapshots Configuration: X-RAID (Expandable RAID), 4 disks Status: Not redundant. A disk failure will render this volume dead. RAID Disks: Ch. 1: UNKNOWN [698 GB] Ch. 2: Seagate ST31500341AS [1397 GB] 694 GB allocated Ch. 3: Seagate ST31500341AS [1397 GB] 694 GB allocated Ch. 4: Seagate ST31500341AS [1397 GB] 694 GB allocated Does anyone know how to make it forget about the fourth drive and give me 3 1.5 X-RAID drives for ~2700 GB? Thank you.
