I have TVS-882 with Raid Group 3, 4 & 5 on Raid 1. Raid Group 3 and Raid Group 5 are using identical 6 TB drives. The capacity listing for Raid Group 3 is 5.45 TB while the capacity listing for Raid Group 5 is 922.02 GB. Can anyone explain why they are different? Did I setup Raid Group 5 wrong or not expand it properly? Thank you for any insights. I have attached JPGs from Disks/VJBOD windows.viewtopic.php?f=25&t=150347

Probably. What's the history?

For anyone with this type of question - how to expand a Raid Group after replacing disk one by one and not choosing Expand during the process. You can go back to Replacing Disks one by one in Storage Pool Management and Select the Raid Group you want to expand and then choose Manage. The problem I had was 1.) Confusion about re selecting Replace Disks on by one because I was afraid it would immediately start removing the disk. Instead of selecting a particular disk and choosing to remove it, look down to the option to Expand it instead. It will then begin a process called "Synchronizing" and will take a LONG time depending on the size of your disks in the Raid Group. For me, it said over 12 hours. 2.) The Manage button for the Volume is easily view-able for selecting, but the Manage button for the individual Raid Group is NOT. You will need to raise the view with the Horizontal window bar to see it and select it. Then the option to Replace Disk one by one will be available. Click on it and you will have the option to Expand the raid group. See https://www.qnap.com/en/how-to/tutorial ... ty-upgrade for clear instructions (unlike mine probably) except instead of replacing the disk choose Expand instead.
For the life of me I am stubborn about figuring things out for myself instead of simply looking through the tutorials for answers. Don't be like me. Now if I can just figure out how to get Plex Server to work properly.

I did this with a SSD RAID1 array and clicking on expand does not increase the RAID capacity despite telling me the expansion process starts and ends in 30 secs......
