RPi 4B, USB Drive share lost upon reboot

moldava · December 10, 2022 at 9:34 PM

Hi everybody

Sorry if this was asked before, but couln't find anything related on the forum.

I just installed LE 10.0.4 on a RPi 4B on a SD Card.

I have a USB drive connected to the RPi that is shared through SMB.

Everything work great, except that upon reboot/restart the external USB drive is no longer shared via SMB, even though the "Auto share external drives" is ON in the libreelec services panel.

If I disconnect the USB drive and connect it again the share is then visible on the network.

Is this an ongoing issue with libreelec on RPi4? or am I missing something?

I have an Rpi 3 with LE and this was not an issue.

Thanks a lot

Is the drive powered from a separate PSU or the RPi? .. If powered from the RPi, connect it to a powered USB hub and test again.

Yes, it's a powered drive.

When I unplug it and plug it again the share reappears and works fine until next reboot.

Please share the system log from cold boot with the drive connected, i.e. "dmesg | paste" and share the URL

Hi, here is the link:

Something I noted, sometimes the mount is shared, sometimes it's not. The log is for a 'non shared instance'.

Thank you so much for your time.

It shows the drive being detected.. can you do "journalctl | paste" and share the URL as this will show more about systemd (which runs the service units that do sharing).

Hi chewitt, sorry for the delay

Heres the link for "journalctl | paste"

I can see the drive being detected, mounted, and samba services starting. No errors .. so no idea what the issue is

Code

Feb 02 12:29:51 rpi4 systemd[1]: Starting Samba Configuration...

Feb 02 12:29:51 rpi4 systemd[1]: Starting Udevil mount service...[...]
Feb 02 12:29:52 rpi4 systemd[1]: Finished Samba Configuration.Feb 02 12:29:52 rpi4 systemd[1]: Finished Udevil mount service.

Can be a race between Samba Configuration and Udevil Mount + autoshare.

What if you create (with path):

Code: /storage/.config/system.d/udevil-mount@.service.d/depend.conf

[Unit]
After=samba-config.service

Thanks, mglae

I created the file with the two lines as you suggested:

Code: /storage/.config/system.d/udevil-mount@.service.d/depend.conf

[Unit]
After=samba-config.service

Here is a new log:

Not sure what all of this does, but I guess it delays the mount share until samba is up.

So far seems to be working, although I just rebooted a couple of times.
