One of two HD USB partitions not accesible on network

Help and Support Raspberry Pi
1

Hi, when I first installed OSMC it mounted both partitions of my external USB HD and they were visible & accesible in my network.

Because I had some problems with transmission I played around with many of the settings trough command line, that I don’t remember anymore.

Anyway OSMC can see both partitions all the time and I can use them without problem read/write. But my ‘Backup’ partition is not visible nor accesible on network.

Thought it might be root root problem so changed it to

It didn’t help and I can’t see “Backup” on network

at the moment my ‘fstab’ configuration doesn’t include any additional entries, and USB HD gets mounted automatically to /media/

is this samba problem?

Thanks for reading any help very much appreciated

It’s not a problem with fstab. This needs to be solved through the samba configuration.

From the little investigating I’ve just done on my own system, it seems like everything mounted in /media should be shared automatically (which was a problem for me, having mounted my drive in /mnt).

There’s just a chance that might be due to default mounting options - at one stage I noticed a difference in read/write permissions between ext, vfat, and NTFS filesystems.
If you need more help, it might assist if you post the outputs of mount sudo fdisk -l

Nothing immediately jumps out.
What are the OS on the system you are trying for network to Backup?
Derek

7

It’s Windows 7

Week ago it has seen both partitions though…

8

With Win7 I’d expect to be able to put \ip address in the address bar of Explorer (not internet explorer), and get the shares appear.
If they don’t, then I’m not sure what to look at.

Why is Backup in your fstab and Filmy is not? Does it not get mounted automatically? Try commenting it out and see if that changes anything.

10

I checked fstab again - nothing else there than

/dev/mmcblk0p1 /boot vfat defaults,noatime 0 0
/dev/mmcblk0p2 / ext4 defaults,noatime 0 0

11

My mistake. Here’s how I got my drives to share properly with samba:

Step 1: Mount both partitions in /mnt/ via fstab:

ie /mnt/Filmy and /mnt/Backup.

It’s my understanding that /media/ is used as a temporary mount space and that permanently mounted drives should be put in /mnt/.

Step 2: Make following change to smb-shares.conf so everything in /mnt is shared.

osmc@osmc:~$ cat /etc/samba/smb-shares.conf 
# Deprecated devices share. If you do not need this you can remove it.
[devices]
    browsable = yes
    read only = no
    valid users = osmc
    path = /mnt
    force user = root
    comment = Deprecated (Please use the Auto-mount Volume shares)
    hide files = /$RECYCLE.BIN/System Volume Information/desktop.ini/thumbs.db/
12

That solved the problem.
I have used

UUID=XxxxxxxxxxX  /mnt/Backup/  ntfs-3g   auto,user,rw,exec 0 0

in fstab, but that was not enough, so added to

/etc/samba/smb-shares.conf

lines you have written for me. Works as a charm now.

I think this is also the solution for my former “permission denied” problem, when I tried to use / set up, Transmission week ago, and was getting this message after first few kb of download.

Magically it later started to work on

/media/

mount, so at least for now I’m going to let it mount there. Plus I would get some hassle with already scraped libraries…
When I’ve “managed” torrent to work [qBittorent] at the same time I have lost “Backup” mount… till now.

That’s the story if anyone can make use of…

Thanks for help in this thread. Much appreciated. You saved my Backups :sunny:
