Systemd automount not unmounted when idle

systemd has stopped unmounting drives when they are idle. This is for quite some time through several updates, not new with the latest update. I have not found anything in forums for Manjaro or Arch mentioning this.

The mounting works perfectly when I access something below the mountpoint, e.g listing a directory with ls. But no matter how long I keep away from the drive, it stays mounted. I cannot find anything that might keep access open to the drive with lsof +D /data/hd1Tb/ .

How can I check what is keeping the drive mounted without activating the mounting?

The systemd unit files seem to be OK and should unmount the drive after 5 minutes idle.
Example:

$ cat /etc/systemd/system/data-hd1Tb.automount
[Unit]
Description=On demand mount hd1Tb on /data/hd1Tb

[Automount]
Where=/data/hd1Tb
TimeoutIdleSec=300

[Install]
WantedBy=multi-user.target

$ cat /etc/systemd/system/data-hd1Tb.mount
[Unit]
Description=mount hd1Tb on /data/hd1Tb

[Mount]
What=/dev/disk/by-label/hd1Tb
Where=/data/hd1Tb
Type=ext4
Options=defaults,noatime,discard
TimeoutSec=10

[Install]
WantedBy=multi-user.target
after 30 minutes of not running ANYTHING on the system

Hmm - as I remember this - the TimoutIdleSec would do that.

I haven’t given much thought to it… I will keep an eye out when I get some more time.

aug 11 09:22:22 statPC systemd[1]: data-hd1Tb.automount: Got automount request for /data/hd1Tb, triggered by 1759 (ls)

triggered by 1759 (ls)


On my system

aug 11 06:21:53 tiger systemd[1]: a-backup01.automount: Got automount request for /a/backup01, triggered by 4385 ((sleep))

triggered by 4385 ((sleep)) - that one is a bit strange - need investigation

aug 11 06:11:26 tiger systemd[1]: a-projects.automount: Got automount request for /a/projects, triggered by 1686 (syncthing)

But this one will keep my device awake for ever…

Something in Plasma keeps the drive mounted.

I booted to runlevel 3 and logged in to the tty and ran lsof +D /data/hd1Tb/ to trigger the automount. Then I waited 10 minutes and then checked with systemctl list-automounts --all , and then the drive was dismounted.

Then I booted normally and logged in to Plasma and opened Konsole and ran ls /data/hd1Tb to trigger the automount. Then I waited 10 minutes and then checked with systemctl list-automounts --all , and the drive was still mounted.

A shot in the dark: thumbnailer, search indexer? But it had to be visible with lsof…

When I installed the system I disabled baloo with

kwriteconfig6 --file krunnerrc  --group Plugins --key baloosearchEnabled false
kwriteconfig6 --file baloofilerc --group Basic Settings --key Indexing-Enabled false

and those values are still in the respective files in ~/.config

There is something which keeps the mount from closing.

In my case it is two user services

  • syncthing - which uses my /a/projects mount point
  • backup - which uses my /a/backuo01 mount point

It may not be obvious - I had to think deep on the sleep activation - it turns out it is a timer that keep my backup device mounted.

Although the timer goes to sleep - it does not release the mount - possibly an error on my configuration of the timer/service combination.
