XRAID turned RAID5 into RAID6 when adding a drive
When I added a drive, my RAID5 config changed to RAID6. Is it supposed to do that?
When you go past 6 disks xraid will turn your RAID5 to a RAID6
"X-RAID® dynamically changes raid RAID1 for 1 - 2 drives. RAID5 for 3 - 6 drives. RAID6 for 7+ drives"
You can try out different setups here:

I agree with the logic (though I wonder what would happen if that conversion required shrinking the volume size - which could be required if the drives aren't the same size).
But I think there should be a confirmation on the UI before the conversion happens.
It's not sensible to use RAID-5 with that many disks.
The volume wouldn't be shrunk. Attempting to shrink a volume is dangerous.

I agree. But I still think a UI confirmation is a good idea. Once it converts, there's no going back. And a user who really needs the capacity might prefer to switch to flexraid, and set up a jbod volume instead.

Understood. So what does happen if I have 2x6TB+4x4TB, and then I add a 6 TB drive to the array?
