ReadyNAS 628 expansion not starting
ReadyNAS 628x running firmware 6.10.8 in RAID6
NAS has operated flawlessly for many years with eight (8) 14TB drives.
A recent drive failure led me upgrade to:
Four (4) 14TB drives
Four (4) 24TB drives
I added the 24TB drives one at a time and waited for it to finish sync before adding the next.
After adding the fourth 24TB drive, no expansion occurred (I expected to gain 20TB)
At this point I noticed the NAS seemed to be in Flex-RAID mode instead of X-RAID. I am not sure why it would be in Flex-RAID mode.
I switched it to X-RAID in the hope expansion would occur. It did not.
I rebooted it, thinking that may spur expansion but it seems not to have.
At this point I'm unsure how to proceed.
Thanks in advance for suggestions!
Some good if mysterious news! Since I was going to have to reformat the system to get more space, I completed upgrading from 14TB drives to 24TB drives. I added the 24TB drives (hot) one at a time letting the ReadyNAS return to redundant status after each drive was added. Adding each new drive took a couple days.
I added the eighth 24TB drive this weekend. Imagine my surprise this morning when I saw the message that it had resynced. FrontView reports that the data volume is now 130.94TB. Apparently, encrypted vertical expansion can occur but only when all drives have been upgraded to a larger size.
For what it's worth, my ReadyNAS 628 is on firmware 6.10.8.

Start by downloading the log zip file. If you need help sorting it out, you can send me a private message (PM) using the forum link in the upper right of the forum page. Upload the full zip to cloud storage, and include a link to the zip. Make sure the permissions are set so anyone with the link can download.
I will take a stab at the log files, but I'm not sure what I'm looking for. I should have mentioned the volume is encrypted which means it was in Flex-RAID mode when I created it several years ago. It's possible I never changed it X-RAID until now.
I should have mentioned the volume is encrypted
Encrypted volumes can't be vertically expanded, so you'll need to destroy the volume and start over in order to use all the space.
Ouch! If I ever knew that, it is long forgotten.
If I recreate the encrypted volume, will the 4x14TB plus 4x24TB drives result in a (6x14TB) volume or a (4x14TB)+(2x24TB)volume?
Thanks for all the help!

I should also mention that the ReadyNAS 628 was in X-RAID mode when the unexpected vertical expansion occurred.
