[Guide for upgrading with more than 12 drives?]

Are there any solid guides to help with the most difficult process in Xepenology?  Upgrading the OS with more than 12 drives?

[Help! You do the math. I had an 11x8TB array, which gave me 65.46TB capacity. I added one final 8TB disk to increase capacity. I spent a few days expanding and came back to no increase in size. I should be around 72.8TB.]

First: Understood.

 

Second:  The first parity check already completed.  There was no option to to expand the volume.  The capacity didn't increase.  This is the second parity check I am attempting in the picture.  I followed those instruction after reboot and the action was no available.

See my post above.  Does anyone here have any suggestions?

 

A few more notes.

-My original array was a Raid5 with 10 x 7.28TB

-My new array is Raid6 with 12 x 7.28TB

-I added two 8TB drives and converted to a Raid 6. The system log stated I successfully changed to Raid 6 with my new drives. But I seem to have lost 7.28TB of space. My raid should have gone from 65.46 to 72.8.

-This is only only raid group.

-I only have 1 volume.

- These are 8TB drives, 7.28 is the raw capacity after partition.

-Im data scrubbing currently manually to see if that makes a difference.

-I have rebooted.
