First, I created AppleRAID JBOD using two 8TB hdd. (choose APFS filesystem and generated single 16TB container.)
Then, I tried to added another hdd drives. But, diskutility apps says 'Operation is failed because can't expand volume'. However, new drive is already joined JBOD members.
So, I can't expand container volume and also can't remove new JBOD member drive.
Is there solution?
This is my appleRAID info. And the result when I tried to remove devices.
