RN212 RAID 0 Space Issue
Originally had a 6TB drive in slot 1 configured in XRaid of Raid 1. Needed to expand space. Changed the system to Flex-Raid and used the Destroy function for the volume. Added a 10TB drive to slot 2 ...
Welcome to the Community!
Due to the disks are on different sizes, the volume will be limited by the smallest disk which in this case the 6TB disk. If you will check on the RAID Calculator., the total capacity available should be around 10.9TiB (11.9TB) and there is an unused space of 3.64TiB (4TB) which is correct since the volume will be limited by the 6TB Disk.
In your case you are only getting 10TB? how much unused space can you see on the volume? I would advise recreating RAID-0 by destroying the volume again but you will not be able to reach the 15TB cap you are expecting. If you want to have that capacity, it would be better if you create a separate volume (JBOD) for each drive. In this way, you will be able to fully use both drive caps.

That is true when you use RAID-0 striping.
But if you start with a single disk JBOD volume, you should be able to create a second JBOD RAID group on the second disk and concatenate them.That ought to give you a 16 TB volume.
Personally I don't recommend doing either though. In both configurations you will lose all your data when either disk fails. I'd go with two volumes myself.
