Ultra 6 plus - SMB not advertised anymore

Ultra 6 plus - SMB not advertised anymore

Hello,

 

ULTRA6 PLUS  6x3TB Xraid2  OS 4.2.28  36% capacity used

 

Suddenly the SMB shares are no more showing on the windows clients - not related to 4.2.28 upgrade.

Shares are still accessible via the IP address, SSH works.

No mods were done recently, all disks are fine.

 

Maybe the CIFS service is not running ? Some partitions get full ?

I spent hours around this and can work my way around Windows and networking but would need pointers for Linux and such.

Any ideas ?

 

Thanks

Benoit

Re: Ultra 6 plus - SMB not advertised anymore

You are saying that \\nasipaddress\sharename works?

 

If so, what exactly is failing?  Just the appearance of the NAS in the file explorer left pane?  Or something else?

Re: Ultra 6 plus - SMB not advertised anymore

Hello,

Yes, the name is not recognized anymore. I thought I got access via IP but in fact not.

Admin & shares are accessible (shares is empty). And Other folders not accessible.

I have SSH & Frontview.

Maybe some service not running ?

Log in with ssh, and check the fullness of the OS partition

df . -h

df . -i

With the SSH GUI, I can browse thru directories. I could download a file - data is still there.

Re: Ultra 6 plus - SMB not advertised anymore

Your OS partition is not full, so that cause is ruled out.

 

Can you see the files with FTP?  

 

Did you try restarting the NAS?

Re: Ultra 6 plus - SMB not advertised anymore

Also, which version of Windows are you running on your client machines?

Is the NAS in the same workgroup as your client machines?

Re: Ultra 6 plus - SMB not advertised anymore

Hello,

 

- I can see the files with FTP

- The NAS was rebooted a few times

- It is in the same workgroup

- The client PCs are WIN7 and WIN10 (tried 3 of them)

- Streaming devices (DLNA players) do not see the NAS anymore either

 

I controlled the parameters

- CIFS protocol is selected

- The shares are defined, with CIFS enabled

- Shares are not made invisible

 

What puzzles me is that it was running fine a few days ago.

I noticed it becoming slow/unstable while listening to some music - I did not investigate.

The next day, no shares anymore.

There were no changes in configuration (NAS or Network) during this period.

During early troubleshooting, I noticed that I lost SSH access. I noticed there was a better OS release and upgraded (using Frontview) from 4.2.27 to 4.2.28 and was happy to have SSH again.

Add-ons work OK (Dropbox, Tonido..). I can also see the files from Tonido.

 

Can I check some logs somewhere or if some 'share' service is running ?

 

Tx 🙂

Re: Ultra 6 plus - SMB not advertised anymore

Per-incident netgear support is the fastest way to get it sorted.

 

You could perhaps try toggling CIFS off/on on the services->standard file protocol page, and checking that it is enabled for each share on the share list.  You could also reset the owner/group for each share on the advanced options page.

 

An OS reinstall is another possibility - it will reset the admin password to "netgear1" and the NAS network configuration to dhcp.

Re: Ultra 6 plus - SMB not advertised anymore

I found in the journal 'An error occured when starting the CIFS service' !

 

Mon Dec 21 12:45:00 CET 2015 Une erreur est survenue lors du démarrage du service CIFS.

 

Where should I go to have more details ?

They should.

Re: Ultra 6 plus - SMB not advertised anymore

There is an error message in the log hat an error occurs when starting the CIFS service !

 

I would feel more reassuring to attempt this troubleshooting first 🙂  Any idea where a detailed log would be ?
