External storage linked to a SMB share

Hello all,

I’m trying to add a local folder which is a share to NextCloud.
I’m facing different problems.

Let me describe how I did first:

The SMB is a windows share //wserver/gd
I’ve added the following line to fstab (33 = www-data):
//wserver/gd /media/gd cifs user,uid=33,gid=33,rw,iocharset=utf8,suid,credentials=/root/.smbcredentials,file_mode=0770,dir_mode=0770 0 0
Changed /media/gd owner to www-data and I did a chmod u+w -R /media/gd
After a mount -a, from root, I can reach any folder inside /media/gd and add/modify any files from terminal
From Nextcloud, I can add the external storage as local dir
From Nextcloud, I can browser the folders with no problems BUT I have the popup “you don’t have the rights to write it”. In some folders, I can add files, some others I can’t.
I’ve checked the permissions of a working folder and a non working folder: no difference

I’m a bit lost. The problem might be related to my local folder configuration but I don’t understand what.

Anyone has a successfully created such an external storage ?

Thank you!

Hi there, you could have a look at this for a working line:

github.com

nextcloud/vm/blob/0ce7f6a4df250f468ea708381ab6eaa4b92d1611/apps/smbmount.sh#L105

    
      
          SMB_PASSWORD=$(input_box_flow "Please enter the password of the SMB-user $SMB_USER." "$SUBTITLE")
          
          
# Write everything to /etc/fstab, mount and connect external storage
          count=1
          while  [ $count -le $MAX_COUNT ]
          do
              # Check which mounting slot is available
              if ! grep -q "$SMBSHARES/$count " /etc/fstab
              then 
                  # Write to /etc/fstab and mount
                  echo "$SERVER_SHARE_NAME $SMBSHARES/$count cifs credentials=$SMB_CREDENTIALS/SMB$count,uid=www-data,gid=www-data,file_mode=0770,dir_mode=0770,nounix,noserverino,cache=none,nofail 0 0" >> /etc/fstab
                  mkdir -p $SMB_CREDENTIALS
                  touch $SMB_CREDENTIALS/SMB$count
                  chown -R root:root $SMB_CREDENTIALS
                  chmod -R 600 $SMB_CREDENTIALS
                  echo "username=$SMB_USER" > $SMB_CREDENTIALS/SMB$count
                  echo "password=$SMB_PASSWORD" >> $SMB_CREDENTIALS/SMB$count
                  mkdir -p "$SMBSHARES/$count"
                  mount "$SMBSHARES/$count"
                  
                  # Check if mounting was successful
