Can't see USB Drive via Samba Server

Help and Support Raspberry Pi
1

Hi, I have searched the forum and found similar questions but not a suitable answer.

My OSMC installation on Raspberry Pi3 somehow got corrupted on the Micro SD card and so I rebuilt it from scratch. With this new fresh installation I can’t reinstate a key facility that I have been using.

What I managed to do was share on my home network a USB drive that was plugged into the Pi using the Samba Server service.

I can see the USB drive locally via the OSMC UI and can browse and play the media content on it just fine.

I can see \osmc\boot and \osmc\osmc via my Windows laptop, which contains empty media folders named Media, Music, TV and Pictures.
I can also do this using \[ip address].

However I cannot see the USB drive attached to the Pi over the network. It just doesn’t appear.

All of this worked perfectly before, so I don’t know what is different about this new installation. I have dredged through all of the settings in OSMC/Pi Config to find an option to expose the USB drive and its folders via the Samba Server but cannot find one.

What must I have done before that I haven’t this time round??
Any help appreciated.

Assuming you have installed the samba server from the app store there is a automount configured that will take care of that.

Provide logs via grab-logs -A and also provide output of testparm -v

Hi fzinken

Samba Server is installed, however I couldn’t find an auto mount setting. Where is that?

Tonight I can try to send over the logs if necessary

4

in smb.conf you have automount template

5

Also, I don’t know if that’s the correct procedure on OSMC, but I had to add user/password to Samba with the command line syntax:

sudo smbpasswd -a user

Substitute user with your actual one.

Load smb config files from /etc/samba/smb.conf

Processing section “[automount template]”
Can’t find include file /etc/samba/smb-shares.conf
Loaded services file OK.
WARNING: socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=131072 SO_SNDBUF=131072
This warning is printed because you set one of the
following options: SO_SNDBUF, SO_RCVBUF, SO_SNDLOWAT,
SO_RCVLOWAT
Modern server operating systems are tuned for
high network performance in the majority of situations;
when you set ‘socket options’ you are overriding those
settings.
Linux in particular has an auto-tuning mechanism for
buffer sizes (SO_SNDBUF, SO_RCVBUF) that will be
disabled if you specify a socket buffer size. This can
potentially cripple your TCP/IP stack.

Getting the ‘socket options’ correct can make a big
difference to your performance, but getting them wrong
can degrade it by just as much. As with any other low
level setting, if you must make changes to it, make
small changes and test the effect before making any
large changes.

I didn’t have to do it before. The share login was the default osmc/osmc previously, which I am using again now to connect to OSMC via Windows File Explorer successfully, although I cannot see the USB drive this way like I used to

Does anyone have any more ideas? Do the logs above help?

15

Yes and as you can see from the output above it is shared successfully.
So this must be an issue on your client.
What client you are using?

16

Right, this is weird. It definitely did not come up in the client (Windows File Explorer) before, all that showed up was the ‘boot’ and ‘osmc’ directories. It now also shows VERBATIM and I haven’t changed anything!

Thank you for your help though!
