Greetings, all.
I have an embedded system that uses a Raspberry Pi 3. I have it set up
and running with the latest Raspbian and all is well, almost. For some
reason the Raspbian system is not set up to automount memory sticks when
they are inserted in to a USB port on the machine.
On another embedded system I needed to install the usbmount package to
get the system to automount a memory stick when it is inserted. I have
installed usbmount on the RPi but it still won't automount a USB memory
stick. The output from dmesg reports that it is seeing the insertion of
the USB memory device. The device is also reported under lsusb.
Why is Raspbian not set up to automount a memory stick like is done on a
normal Linux based desktop? My desktop does it and I don't have an
usbmount package installed. How do I configure Raspbian to automount a
memory stick?
Normally it's something with systemd or udev rule flags. I had to google
it as I'm
not aware of all the rules. See if this works:
Make sure it works by changing MountFlags=slave to MountFlags=shared
here:
sudo nano /lib/systemd/system/systemd-udevd.service
Not sure this helps,
Nick
On a headless web server here, up-to-date Raspbian, dmesg shows that
plugging in a USB flash drive creates a device /dev/sda and /dev/sda1 .
These devices disappear when the flash drive is unplugged.
The SD chip serving as the 'hard-drive' is present as /dev/mmcblk0 .
In Raspbian with the full GUI, something in the GUI catches a plugged-in
flash drive and mounts it under /media/username . I don't know how.
udev?
That is correct it's udev or the part of systemd that does it. I mentioned it my
previous email but your package should work. The problem is the flag in
/lib/systemd/system/systemd-udevd.service. Seems this needs to be
MountFlags=shared
instead of slave. I would check to see if MountFlags in that file is set
correctly
first.
