and I ended up with the same size volume that I started with. A couple of hours ago the PR4100 completed the expansion drive process that I attempted the first time. I recall that two days ago I saw the screen that had the slide bar on it, but I didn't slide the bar. As I am writing this my PR4100 is in the process of the (correct) expansion process. I suspect that is the same mistake that others made as well. That is what I did the first time that I attempted to expand the size of my volume. The problem is that it doesn't look like a slide bar (or I didn't recognize it as a slide bar ) and if you don't slide that little blue indicator on the bar so that you move it to the right, and then you proceed with the drive expansion, you will end up with the same size volume that you started with. In Raid 5, once that you have replaced the original drives with larger drives, (one at a time, and waited for each drive to be rebuilt before changing the next drive), go to the home screen and click on "change raid mode" and then you progress through the screens making your selections along the way ( you want to leave the raid mode as raid 5, and you want to indicate that you are NOT changing your drives because you have already done that ), you will come to a screen with a slide bar on it that you use to indicate how much of the new capacity you want to use to expand your volume. I think some people think it is simply an informational screen. In the process of expanding the volume size those who have run into a problem probably missed the following : There is another screen that one encounters along the expansion drive process, and anyone with a problem has not posted it (that I have found). so here is a solution that is (was) hiding in plain sight from a lot of people (myself included). An option would reveal itself to expand the capacity. These are the steps I took, after manual rebuilds on each Drive 1-4. Screen Shots: I can't show each step because I am attempting a second pass at Expansion. New Capacity should be around 18*3=54TB storage New Capacity 4 x 18TB RAID 5 ~ 18TB storage (still) Old Capacity 4 x 6TB RAID 5 ~ 18TB storage I don't think this will work and already regret clicking the button to proceed.Īnyone experience this? I've rebooted also, so FYI. I am now trying a second pass in Expansion. I was "Warning 95% capacity", and still same capacity reading on new drives (4 x 18TB in RAID 5).Įach Drive's "Disk Status" registers as 18TB, but still in RAID 5, it reads 18.xxTB, with <1 TB? And still, my WD NAS PR4100 reads my smaller RAID 5 total drive space. Step 4) Wait a couple days for this operation to finish. (because I just rebuilt all drives with new drives already) Select: Storage > RAID > Change RAID Mode > Expansion. Step 3) All NEW Larger Drives are now in. Step 1) Replace Drive 1 Do manual rebuild with new larger-capacity drive. First I tried cloning the drives that didn't work.
