Unable to activate the SMB

Hi,

Since several days I had an unexpected disabling of my SMB on the ReadyNAS.

I'm trying to reactivate the service but each time the App button go back to grey status.

Do you have an idea of the root cause ?

Thanks

      How full is the OS partition (/dev/md0)???

       

      Do you have a backup of your files?

  • Very odd, I lost all shared accesses

    But I was able to restore them and activating the SMB from the shared folder

    That is usually the result of a corrupted configuration file, and a typical cause for that is a too-full OS partition.  If that is the case, you'll see warnings about it in the log.  There are things that you can try (using SSH and the Linux command line) short of a full reset, but we need to know what's the root cause, if possible.  If the OS partition is too full, do not do an OS re-install -- it'll most likely make the problem worse.

      I don't see full OS partition

      I started now a defrag of the system

      I have 2.63TB free space on disks

  • I downloaded the full log zip but hosnestly I don't know where to check...

    I read the SMBstatus but I see only this string: using configfile = /etc/samba/smb.conf

      If the OS partition is too full, the warnings are in the main log you can view from the UI.

        If you like, you can send me a PM with a download link, and I will take a look.  

         

        Make sure the permissions are set so anyone with the link can download.

  • What do you mean by full OS partition? A full reset of the RN?

      Linux, the ReadyNAS software, and the configuration files are all saved in a 4 GB OS partition on the disks.  If that gets full, then many things can go wrong.  That includes config settings that don't "stick".

       

      The logs page errors normally call this a "full root".

       

      You can also see how full the OS partiton is by looking at the end of volume.log  Scroll down to the "df -h" section and look at /dev/md0:

      === df -h ===
      Filesystem      Size  Used Avail Use% Mounted on
      udev             10M  4.0K   10M   1% /dev
      /dev/md0        4.0G  981M  2.8G  26% /

    Is this with an RN312?   If not, then what model NAS?

     

    Have you looked at the full log zip?  In particular, did you check for a full OS partition?

      Hi StephenB,

       

      Glad to see you again on forum since long years :-)

      My model is the RN422

      I just saw the log from RN I saw just an error with the AV updating (it's a know issue from RN endlife  as I read)
