You factory defaulted this unit in Flex-RAID, not X-RAID. X-RAID would expand your disks to 2 disk expansion. As such, you're currently using a RAID 0 and can't expand that. You should backup your data, factory default, and use X-RAID if you want redundancy. If you want another RAID 0 and possible risk of losing all of your data, then you should factory default with both disks in place and use Flex-RAID to choose your RAID option. Your other option right now is to add the new disk as a new volume.

The messages you are getting about resyncing arrays is because we add the OS and swap partitions to your new disk and resync those for redundancy of those options. We wouldn't do anything with the data volume area in Flex-RAID.

In my opinion that is better than a single RAID-0 volume. Certainly it is more robust (a 2-disk RAID-0 volume loses everything if either disk fails).

  Thanks for your reply. At the first setup i set JBOD, because i dont need redundancy. Later i added a second 2TB disk, which was operated a second volume. This disk went wrong, and i removed that.
  I dont understand why i am not able to add a new disk as a new volume. I never used RAID 0 or 1.

    If you use http://www.readynas.com/download/addons/arm/5.3/Enable_Remote_Access_1.0-arm.bin <-- this addon and PM me your admin password (feel free to change) and the 5 digit code from the notification, I will have another look. (Maybe I can also fix your OS which may have some fs corruption as well).
