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

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.

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

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% /

So it doesn't look like that's what has caused the configuration file corruption (most likely smb.conf or one of the files listed on an INCLUDE line in it) . Do you have a saved configuration file before this started happening and before you added any new shares? If so, you can try uploading that. smb.conf is re-written every time you add or delete smb access for a share, so you can try just making a change there, too. Or you can wait for StephenB to take a look at your downloaded .zip and see if it points to a more specific problem.

  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)

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

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

Very odd, I lost all shared accesses
But I was able to restore them and activating the SMB from the shared folder

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

I have a new information over the SMB issue, when I'm trying to start the SMB service, an error pop-up is shown...

  This is not an error I've seen before.
  
  Do you have any NAS user accounts that you are not using anymore? If you do, then try deleting them.

  There is - but it is built in, not something you configure from the NAS web ui.
  
  If a device tries to access a share without using a NAS user account credential, then the NAS will use Guest (which amounts to anonymous access).

Hi,
Currently I'm trying to make a backup before to do factorry reset of my ReadyNas but the device is completly unstable like a DDOS of the WebUI...so often busy to download the Web page , restarting the logging popup...
I'm searching a solution for this manual backup of my data before the reset

  Do you have access to a linux system?

    Unfortunately no :-(
    
    I forced the poweroff from the front panel.
    I bought a new external SSD 2TB and an eSata/USB-C cable to make the ReadyNas Backup.
    
    I restarted the ReadyNas, it seems more stable, I have access to WebUI now.
    I connected the new external SSD (formated in GPT with a NTFS partition) on the eSata...nothing on the WebUI, same with the rear USB. Only the front USB can find/start the external SSD.
    I think there a hardware problem with the rear USB and eSata.
    So now, I started the full backup of the ReadyNas on my external SSD Samsung 9100 2TB, faster than my previous external disk.
    I let you know when it's finished...after that I will try a factory reset of the ReadNas and check if the SMB service can be enabling or not after this master reset.
    If not, I will open an RMA ticket to Netgear support because my RN422 still under official warranty for 1 month

I did the factory reset, the SMB is back now, but I have odd behavior with AV. Also with my eSAta2USB-c, which I'm unable to connect an external disk, only on the USB ports

  Can you give more details?

  I never had much luck with eSATA myself (either with ReadyNAS or with a PC). Though it's been a long time since I tried it (and I never tried an eSATA to USB-C adapter).
  
  Although the older linux on the ReadyNAS sometimes doesn't handle USB hubs properly, you can try connecting one to the USB output on the back and see if that works.
