Remove inactive volumes

I got a new NAS today. And, max unluck, my old NAS failed today.

 

How can I get this old nas up and go so i can copy my files.

 

( i have backup, but backup is incremental since 2009 and that will be a big job to sort out)

    Why did I not think about root... thanks

     

    Here is what happened when I run the command

    btrfs rescue zero-log /dev/md126

  • Hi littomalt 

     

    Would you mind throwing the logs over to me and I can take a look. System > Logs > Download Logs. It will give you a zip file with the NAS logs. Upload this zip file to a Google Drive, Dropbox or similar and PM me the link.

     

    Cheers

      Hi littomalt 

       

      Thanks for the logs.

       

      Your raid and your disks are OK. Healthy. The issue is that the BTRFS filesystem cannot mount and thus you see the cryptic "Remove inactive volumes" message.

       

      Your issue looks to be pretty much exactly the same as this user here:

      https://community.netgear.com/t5/New-ReadyNAS-Users-General/rndp6000-inactive-volume-data/m-p/2093064#M45660 

       

      The NAS cannot mount your filesystem because the journal (log tree) seems to be messed up or corrupt.

      I will give you the exact same advise as I gave the user, in the above post - have a read at it. You also have issues with the same raid device, md126 so everything I said to that user, applies to you as well.

       

      Any questions, let me know :)

       

      Cheers

        Hi

         

        Thanks for your rapid answer rn_enthusiast 

         

        I ssh to NAS as admin but comand did not kick in

         

        admin@Modesty:~$ btrfs rescue zero-log /dev/md126
        -bash: btrfs: command not found

         

         

        Something I dont understand?

      Hi

       

      rn_enthusiast Thanks for the support. For this forum I unsually only asks, I dont have the know how, so when I get help, and specially like yesterday where you saved me a lot of truble I get euforic and want to add something extra!

       

      Regarding backup, I have had jottacloud since the service started, and I have done backup "like *.* -> jotta" for more than 10 years, you can imagin how my backup looks, everytime i reanrange something, or change a directory name the backup is "degrading". I coose this strategy, it is not perfect, but then I have it all.
