ReadyNAS Duo v2 - can't add a second disk

Hello,


closed thread found for this problem: i can not add a second disk for my ReadyNAS Duo v2.

Two types of disk also been tried: WDC WD5000AAKX, Samsung HD103SJ.

That's all I can see in the log: 

New disk detected. If multiple disks have been added, they will be processed one at a time. Please do not remove any added disk(s) during this time. [Disk 2]

I waited for several hours, but nothing happens.

  • 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.

    Hi Do-It-Yourself,

     

    Welcome to the community!

     

    Which RAID is in running your system? Also, kindly send me a PM together with the serial number of your system.

     

     

    Kind regards,

      Thanks for the quick response, I sent the PM with SN.

      I use JBOD with one disk (WDC WD20EARX), and now i want to add a second disk.

       

      StephenB: tried both, but none of them work.

      Currently installed: 

      Disk 1 WDC WD20EARX-00PASB0 1863 GB (34 °C / 93 °F, Write-cache On). Status: OK 
      Disk 2 WDC WD5000AAKX-001CA0 465 GB (35 °C / 95 °F, Write-cache On). Status: OK

        Are you running 4.1.x or 5.x firmware?

         

        Also, you are saying you chose flexraid when you set up the NAS?

         

        Normally with flexraid after you add the disk, you'd select it and create the volume.

  • I can send someone to the whole log file or i can paste it parts, if you specified which is need.

      The disk you added has 13 ATA errors.

      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.
