How do I change my ReadyNAS Ultra series, Ultra Plus series, NVX Pioneer, or Pro Pioneer storage system from X-RAID2 to Flex-RAID?

You can reconfigure your system from X-RAID2 mode (the factory default mode) to Flex-RAID mode.

To change from X-RAID2 to Flex-RAID, follow these steps:

If any data is stored on your system, back up your data.

For more information, see the How do I back up data stored on my ReadyNAS Ultra series, Ultra Plus series, NVX Pioneer, or Pro Pioneer storage system? support article.
Perform a factory reset reboot.

WARNING!

Setting your ReadyNAS system to its factory defaults erases all data and configuration settings.

The process for performing a factory reset reboot varies by storage system.

For more information, see the following support articles:
During the factory reboot process, you have a 10-minute window to choose a RAID configuration. RAIDar sends a prompt to click the Setup button during this 10-minute time frame.
Launch RAIDar, highlight your storage system, and click the Setup button.

The ReadyNAS Volume Setup screen displays.

If you do not select a format within 10 minutes, your system reboots in the same mode that it was previously using.
Select the Flexible Volume (Flex-RAID) radio button.
Select a RAID level from the Select the desired RAID level drop-down menu.

If you select Auto, your ReadyNAS system automatically chooses a RAID level based on the number of disks that are installed in your system, as follows:
Click the Next button.

You are prompted to confirm the volume creation command.
Click the OK button.

The volume is formatted. This can take quite a while, depending on the size of your hard disk drives.
