Data Degraded

I started with a 3TB Drive in my RN204 and I just put a 6TB drive in. And now I'm getting Data Degraded??? What does that mean and what should I do?

    That will work.  You are still wasting 3 TB of space on disk 2 of course.  If you put 6 TB into slot 3 you'd end up with 9 TB of space.

  • Ifr you started with only 1 disk then you did not have Raid protection. When you put in a new disk then RAID is activated and your data gets distributed over the second hard disk as a mirror. During that time you do not have reduncancy so it will take half a day to rebuild to RAID 1.

      One more thing, adding a 6 TB as disk 2 to a NAS that has a 3 TB disk 1 will not give you more disk space. It will stay 3 TB but youre data will be protected on 2 disks. You can ofcourse choose not to have RAID 1 but JOB then you will have 9 TB but no data redundacy.

       

      In order to have 6 TB with Raid you need 2x6 TB's. But wait until the RAID has completed and the degraded message is gone to replace the 3 TB.
