I've searched on this topic for a while before I bought my new drives. First I tried cloning the drives; that didn't work. So I did the "preferred" method. Replace and rebuild each drive in order.
Step 1) Replace Drive 1; Do manual rebuild with new larger-capacity drive.
Step 2) Do step 1 on Drives 2, 3, 4. Done.
Step 3) All NEW Larger Drives are now in. Log in,
Select: Storage > RAID > Change RAID Mode > Expansion.
Change / Swap / Replace Drives?
No. (because I just rebuilt all drives with new drives already)
Step 4) Wait a couple days for this operation to finish. A week of life already invested.
I did all these steps. And still, my WD NAS PR4100 reads my smaller RAID 5 total drive space.
I was "Warning 95% capacity", and still same capacity reading on new drives (4 x 18TB in RAID 5).
Each Drive's "Disk Status" registers as 18TB, but still in RAID 5, it reads 18.xxTB, with <1 TB?
I am now trying a second pass in Expansion.
I don't think this will work and already regret clicking the button to proceed.
Anyone experience this? I've rebooted also, so FYI.
HELP! Please and thank you!
In case there was confusion.
Old Capacity 4 x 6TB @ RAID 5 ~ 18TB storage
New Capacity 4 x 18TB @ RAID 5 ~ 18TB storage (still)
New Capacity should be around 18*3=54TB storage
Screen Shots: I can't show each step because I am attempting a second pass at Expansion.
These are my current Drives.
This is current.
This is what would happenThese are the steps I took, after manual rebuilds on each Drive 1-4. An option would reveal itself to expand the capacity.
This is what should be as a result.
