Raspbian OS (Raspberry Pi) do not mount USB drives automatically out of the box.<\/p>\n\n\n\n
I’m pretty annoyed by the lack of easy to use packages by 2021 and I still have to do it myself with the instructions here: https:\/\/github.com\/avanc\/mopidy-vintage\/wiki\/Automount-USB-sticks<\/a><\/p>\n\n\n\n These are cookbook instructions, but I’ll add some insights to what each component means so it’s easier to remember the steps.<\/p>\n\n\n\n At top level, to auto-detect and mount USB drives, we need the following components<\/p>\n\n\n\n Create the file This automount script is adapted from https:\/\/raspberrypi.stackexchange.com\/questions\/66169\/auto-mount-usb-stick-on-plug-in-without-uuid<\/a> with my improvements.<\/p>\n# Register udev event handler (rules)\n# \/etc\/udev\/rules.d\/usbstick.rules\n\nACTION==\"add\", KERNEL==\"sd[a-z][0-9]\", TAG+=\"systemd\", ENV{SYSTEMD_WANTS}=\"usbstick-handler@%k\"\n\n# It triggers a systemd call to \"usbstick-handler@\" service registered under \/etc\/systemd\/system\/<\/code><\/pre>\n\n\n\n# Register systemd service\n# \/etc\/systemd\/system\/usbstick-handler@.service\n# (Note: instructions used \/lib instead of \/etc. It's better to add it as \/etc as this is manually registered as user-defined service rather than from a package)\n\n[Unit]\nDescription=Mount USB sticks\nBindsTo=dev-%i.device\nAfter=dev-%i.device\n\n[Service]\nType=oneshot\nRemainAfterExit=yes\nExecStart=\/usr\/local\/bin\/automount %I\nExecStop=\/usr\/bin\/pumount \/dev\/%I\n\n# %I is the USB stick's device name under \/dev, usually sda\n# Abstracted the logic of determining the mount point name and mounting to 'automount' (see below)<\/code><\/pre>\n\n\n\n\/usr\/local\/bin\/automount<\/code> <\/code> and give it execution permission<\/strong>: chmod +x \/usr\/local\/bin\/automount<\/code> <\/code><\/p>\n\n\n\n#!\/bin\/bash\n\n# $1 (first argument) is usually \"sda\" (supposedly USB stick device name) seen from %I in the systemd service commands\nPART=$1\n\n# Within the \"sda\" (USB stick device of interest), extract the partition labels (if applicable) from lsblk command.
