X-Raid 4TB to 2 Volume 8TB... possible?
Hi everybody, this is my first post. I originally had a ReadyNAS 102 with a single 4TB drive in it. After buying another 4TB drive the configured X-Raid rebuilt fine, I now have a secure 4TB vol...
You cannot change the raid level without erasing all data.
Doing the following without a backup is risky.
You could remove the second disk and put it in a USB caddy and attach it to the NAS, format it,then back up your data to it.
Once you have done this and verified the backup, you'd need to destroy the existing raid 1 volume and recreate a raid 0 volume in flex raid on the disk that is in the NAS.
After doing this, copy the data back to this new volume from the USB disk.
You could take the USB disk and put it into the NAS, then create a new volume on the second disk.
The problem with all of this is that you have no protection against a single disk failure from the point at which you format the USB disk, and you have no protection against a hardware failure or 2 disk failure at any time. Not sensible if any of the data is irreplaceable.
