I had a PR4100 with 4x6TB drives in RAID 5. I upgraded the drives to 10TB one at a time, rebuilding the RAID each time. All went well, no issues. The PR4100 recognizes they are 10TB in the RAID but does not show any additional freespace. How to I expand the existing volume? I don’t want to create another separate volume.

Capacity expansion is only possible on RAID 0, 1, 5 and 6. Please keep in mind, there should only be “1 virtual drive” on the array. If you have more than 1 virtual drive, then you cannot enlarge your array.
