Multiple NAS drives in a non-RAID (JBOD) configuration?

I have a Netgear ReadyNAS214 (latest OS) which had a single drive as it was/is intended as a backup to machines on the network – "JBOD", no RAID required or wanted.

 

When I introduced a second drive, the NAS OS immediately started setting the two up in a RAID config – not what I was after. All I want is the two drives (well, their shares) to be visible as separate resources.

 

I aborted that process, shut it down and rebooted with just the second drive present.  Now that is all set up as a (solo) JBOD with shares, all working OK.  But I don't want to put drive #1 back in and risk the NAS going rogue-RAID on me and destroying 100GB of stored backup.

 

Obviously I'm missing something needed to achieve the desired "dual JBOD" configuration. Any suggestions?

  • Did you try to do a factory default?  That would be needed if you were still using XRAID.  I thought based on your earlier post that you have already gone back to JBOD.  FWIW, it wasn't needed to simply add a JBOD volume.

     

    In an event, if that is what you are doing, then the NAS admin password has been reset to password.  The NAS will by default use XRAID.  So when you get past the wizard, you should

    • switch to flexraid
    • destroy the data volume
    • create two jbod volumes, one for each disk

    There is no need to wait for the XRAID volume to build/resync.

    Change to flexraid before you add the second disk.  You do that on the volume page - if there is a green stripe on the XRAID control, then XRAID is enabled.  Click it, and the system should change to flexraid.

     

    Then select the disk on the volume page after you hot-insert it.  If the disk is used, then you'll need to use the format control on the page.  After that, create a second JBOD volume.

     

    I suggest reading through chapter 2 of the software manual ( http://www.downloads.netgear.com/files/GDC/READYNAS-100/READYNAS_OS_6_SM_EN.pdf ).

      Your first para sounds like a contradiction.

       

      I have read that Chapter 2.  All I took away from that was a sore head, and re-reading it didn't help one bit.  I came here hoping to find a simple step-by-step solution.

        I fixed the typo.  And my response above does provide the step-by-step solution

        1. switch to flexraid (making sure there is no green stripe on the xraid control)
        2. add a disk
        3. format if needed
        4. create a new volume using that disk

        Then of course create shares on it.

         

        Though flexraid may sound complicated, using jbod with one disk per volume isn't hard.
