SMB/CIFS Can't mount windows root share



Hi all,

First i am french so sorry if my english is not perfect.

I am using NextCloud 13 under Ubuntu 18 , all is up to date.

I have some External Storage perfectly working with my Windows 10 share but only with subfolder.

ie :

// is working
// is NOT working

( \\\d on all my other windows, it’s working too )

In shell, this work perfectly :

sudo mount -t cifs // /mnt/test -o user=pinkfloyd

It seem a NextCloud problem because :

  • In the External Storage apps I have the green symbol
  • In My files view i can’t see the share
  • In External Storage view i CAN see the share, but if i click on it, it reload the folder view.

Hope i have explain my problem correctly, if you need more information don’t hesitate.

Here is a screenshot, the third and last one is not working :

More weird , the “SMB test” apps work :

Thanks a lot !


no one please ?


Any entries in Nextcloud log when trying to access the external share?


Thanks for the reply ^^

Nothing but my usual spam message:

PHP Startup: Unable to load dynamic library ‘’ (tried: /usr/lib/php/20170718/ (/usr/lib/php/20170718/ undefined symbol: igbinary_serialize), /usr/lib/php/20170718/ (/usr/lib/php/20170718/ cannot open shared object file: No such file or directory)) at Unknown#0

( as i already find somewhere that is’t not critical one )

or i dont’s search in the good log file ( i am new to unix world )

Perhaps need to change my loglevel ?

‘loglevel’ => ‘2’,
‘log_type’ => ‘file’,
‘logfile’ => ‘/mnt/ncdata/nextcloud.log’,
‘logtimezone’ => ‘Europe/Paris’,

Sharing SMB/CIFS external storage at root level?

For information ; New version 14 have the same “problem” :frowning:


Upgraded today in version , same issue, no one else have this problem ?

“SMB Test” application show me correctly all folder, so root share is correct, but NextCloud still doesn’t want to mount it :frowning:
