RN516+ Remove inactive volumes to use the disk (1 to 6)

Hello,    I purchased new 8TB drives to replace my 6TB drives.   I proceeded with removing the first 6TB drive and plugged in a new 8TB drive. My nas started syncing this drive, taking up to 10h....

Issue is now, my little son came and pulled out the second drive during the sync.

 

But nothing, after several reboots, i still always get the same message: remove inactive.. 1 to 6.

 

Options are 

  1. rebuild the NAS with the new drives all in place, reconfigure it, and restore data from backup.
  2. use ssh and attempt to force remounting of the volume
  3. contact Netgear paid support (my.netgear.com).  You might need data recovery. https://kb.netgear.com/69/ReadyNAS-Data-Recovery-Diagnostics-Scope-of-Service
  4. connect all 6 disks to a windows PC (likely requires a USB enclosure) and purchase ReclaiMe data recovery software.

Of course (1) assumes you have a backup.  (2) assumes working knowledge of linux commands and the btrfs file system.  You shouldn't attempt it if you don't already have that knowledge.  (3) and (4) are both potentially expensive - my guess is that (3) would be cheaper.

Hi Stephen, 

 

Thank you for the quick reply.

 

So no backup of the complete volume, just the most important.

 

The device i bougth in march 2016 and i registered it, i have a 5 year warranty with it but when i connect on the netgear portal it says expired like 2 months after purchase..?

 

Basically i still have 2 years of support.. what to do to get this support.

 

I could connect the drives to my computer and install ext drivers but it would be a complete hassle. 

 

I guess with the support that i still should have, i would be able to restore some access..?

 

Thank you,

    Warranty support does not include data recovery.  You do not have a hardware failure, so I think you'll find little to no warranty support for your problem, even if it doesn't require recovery.

     

    If the slide lock on the drive eject mechanism (which many do not use) is not sufficient to keep your son from ejecting drives from the NAS, you do need to find another way.  If he'd removed two drives not during re-sync, you'd be in the same place.

     

    In the future, step one in drive replacement is to update your backup.  Going through that many re-syncs is hard on the drives, and one that is nearing failure can be pushed over the edge by the process.

    The system came with a 5 year warranty - but as Sandshark says, this is not a warranty problem - nothing failed, the root cause of the issue amounts to user error.  Support is not the same as warranty.

     

    The RN516 also came with a couple of months of phone support.  Systems purchased between 1 June 2014 and 31 May 2016 also should have lifetime chat support.  You could try that, but I don't think that will be enough to get your volume mounted.  If you can't activate the chat support, try sending a private message (PM) to JohnCM_S or Marc_V and see if they can help with that.  Send a PM by clicking on the envelope icon on the upper right of the forum page.

      Hi StephenB,

       

      Thank you for the reply, i was finally able to find out some time to see if i can rebuild the volume.

       

      So after i was able to ssh, i do see my 6 drives (5 x 6TB and 1 spare 8TB)

       

      i see the 6 drives as RAID5 with the data i have when i execute this command:

       

      sudo mdadm --examine /dev/sd[abcdef]3

      Result:

mdadm: No arrays found in config file or automatically

      I only see /dev/md0 and md1 but i do not see /dev/md/data-0 which is my 27TB volume Raid5

       

      the MD0 and MD1 are raid10 and 1 with only a few GB in it.

       

      What should i do to see the /dev/md/data-0 to be able to force it?

       

      For the chat support, i need to look into it also.

       

      Thank you,

      Hi Stephen,

       

      Thx for the reply, i was able to deep into the issue through CLI.

       

      I found out that i do not see the volume i want to restore with the command

       

      mdadm --assemble --scan (--force) 

       

      result for this is, were it claims only to see 4 drives and 1 spare instead of 5 and 1 spare. it is that 1 missing drive in that array that messed up the volume data-0.

       

      root@NaS:/etc# mdadm --assemble --scan
mdadm: /dev/md/data-0 assembled from 4 drives and 1 spare - not enough to start the array.
mdadm: No arrays found in config file or automaticall

       

      I only see the volume /dev/md0 and md1 (raid1 and 10) but not dev/md/data-0 (Raid5)

       

      but If i launch following command, i see all 6 drives, 5 x 6TB active and 1 x 8tb the new spare drive.
