Raspberry Pi and a Synology NAS

[tarads]

I'm new to the raspberry pi (and linux in general) and for the life of me can not figure out what I'm doing wrong here. Basically... I have a raspberry pi running Deluge. It works perfectly and I was able to get it running following a How-To-Geek blog post.

The issue is that I have no idea how to get my raspberry pi to communicate with my Synology NAS.

A bit of background, I have a program on my NAS that searches for files to download, sends the torrent file to Deluge and then moves said file to its appropriate folder once the download is complete. The NAS program is sending files to the Pi just fine, but the Pi isn't seeing the NAS. Before setting up my raspberry pi I had Deluge running on windows and was able to point to the NAS using //NAS/Data/Folder, but that no longer works on the Pi.

I've tried googling and following this: https://alextheedom.wordpress.com/raspb ... nas-drive/

But that only gets me an error at the "mount –a" step. Thoughts on what I'm doing wrong?

There is an error in your /etc/fstab. fstab is just a text file, when you "mount -a" it tries to mount everything in there.

The first field in the line is the UNC path to your NAS share, only with forward slashes instead of backslashes. In your case: //NAS/Data/Folder

The second field is the local mount directory. This directory must exist locally.

fstab entries are one line only, make sure you didn't add the last half as a second line.

There is a space after "cifs" where the blog wraps the line.

Make sure you didn't add spaces in the option list between workgroup and xattr.

If the share is password protected you will have to add username / password options.

Thanks for the reply.

First, I forgot to post the error that I'm getting. It is:

Code: Select all

Retrying with upper case share name
mount error(6): No such device or address
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

I've tried putting in exactly what the linked webpage says, and had that error. After googling I found someone say to the line that is below. I have that exactly (though with the correct username/password):

//192.168.1.5/NAS-Home /home/pi/myNAS/myShare cifs workgroup=WORKGROUP,username=user,password=password 0 0

It is all posted on one line.

Am I missing something?

[myoung008]

That error is telling you it can't find the network share, either the host or the sharename. Most likely there is a problem with the UNC path. Check that capitalization matches what's on your NAS exactly. I don't think that the dash in the share name would cause a problem, but just in case, try enclosing the path in a single quote. Also, if you've changed the workgroup on the NAS you will need to change the workgroup option to match.

Code: Select all

'//192.168.1.5/NAS-Home' /home/pi/myNAS/myShare cifs workgroup=MYACTUALWORKGROUP,username=user,password=password 0 0

[tarads]

Thanks for the reply.

I double checked on the NAS and the workgroup name is still WORKGROUP. So all good there. I attempted to add the single quote and now am getting this error:

Code: Select all

mount.cifs: bad UNC ('//192.168.1.5/NAS-Home')

[myoung008]

The single quotes obviously won't work then, they can work on the command line but apparently not in fstab.

Try the following:

Code: Select all

smbclient -L 192.168.1.5 -U username

Replacing username for the correct username of course. It may help you figure out what path you need. You can post it's output and I'll try to help further if the answer doesn't jump out at you.

Sorry about the delay in getting back to you, things got busy and I kept putting it off. Here is the result:

Code: Select all

Domain=[WORKGROUP] OS=[Unix] Server=[Samba 4.1.16]

        Sharename       Type      Comment
        ---------       ----      -------
        NAS Home       Disk
        web             Disk      System default shared folder
        IPC$            IPC       IPC Service ()
Domain=[WORKGROUP] OS=[Unix] Server=[Samba 4.1.16]

        Server               Comment
        ---------            -------
        NAS-HOME
        LIVINGROOM-PLEX      OpenELEC

        Workgroup            Master
        ---------            -------
        WORKGROUP            LIVINGROOM-PLEX

I've tried using NASHOME, NAS-HOME, NAS Home, and every other combo I can think of, still nothing.

You may get away with using \040 (zeroes) in place of the space in fstab.

Code: Select all

//192.168.1.5/NAS\040Home /home/pi/myNAS/myShare cifs workgroup=MYACTUALWORKGROUP,username=user,password=password 0 0

I just searched and found that as I've always avoided spaces in sharenames before. I have also seen a reference that it doesn't work in some situations (though it wasn't specific). If it doesn't work for you my suggestion is to change the sharename on the NAS to avoid the space.

Hope this helps.

[tarads]

Thanks, I'll give this a shot tomorrow!

[tarads]

Just wanted to come back and say thanks! Sure enough the error was being caused by that stupid space in the name. Changed that and sure enough everything worked like a charm. Go figure!

Thanks again, you were a huge help!!!

[myoung008]

Excellent! Glad I could help.

[tarads]

So... weird related issue that maybe you can (again) help me with.

After putting the line in /etc/fstab, I can then "mount -a" and the NAS is mounted and works great. The problem is that after a reboot the NAS isn't mounted. If I manually type out "mount -a" everything works again, but continues to go away after a reboot.

The line I ended up suing in fstab is this:

Code: Select all

//192.168.1.5/NASHome /home/pi/myNAS cifs workgroup=WORKGROUP,username=admin,password=password,users,auto,user_xattr 0 0

Thoughts?

Does your NAS support using NFS rather than CIFS?

If it does you'll find it's a) quicker, b) easier to manage and c) works with the Linux security model (no passwords in fstab).

[drgeoff]

Synology NASs do have NFS support. It can be enabled from Control Panel, File Sharing, File Services.

[tarads]

Thanks for the replies. Im not at home but will enable NFS later today.

Can you link or explain how to auto mount the nas via NFS?

Thanks!

[DougieLawson]

sudo nano /etc/fstab and add a line like

Code: Select all

192.168.xxx.nnn:/dir/subdir/nfs/server /srv nfs defaults 0 0

with appropriate values for the IP address and the NFS share.

You can find NFS shares with a showmount command
pi@apollo:/var/log$ showmount -e 192.168.xxx.nnn

Code: Select all

Export list for 192.168.xxx.nnn:
/dir/subdir/nfs/home           192.168.xxx.0/24
/dir/subdir/nfs/server         192.168.xxx.0/24
/dir/subdir/nfs/shared         192.168.xxx.0/24
pi@apollo:/var/log$

Managed to get it mounted via NFS. But still having the same issue of it not being mounted after a reboot. I have to manually go and "mount -a" before the NAS will show up. Thoughts??

[tarads]

Bump? Anyone?
