[SOLVED] systemd fails to unmount home and temporary directory

Edit: Marking this thread as solved. It's not but I'm going to reinstall minus the encryption. It was probaby overkill for my needs in the first place. Apologies if I've wasted anyone's time looking into this.

Hi guys,

I'm having a few problems with poweroff and reboot taking an inordinate amount of time on a fresh install. I've got boot and an encrypted root on an SSD and an encrypted home on a HDD, which is unlocked by a keyfile in the root directory.

Added "verbose" to the kernel line to see what's going on and it shows stop jobs for home are taking upwards of a minute. Eventually, it fails to unmount both home and the temporary directory. Tried adding "shutdown" to the mkinitcpio hooks but it makes no difference.

Below's my fstab and some of the error messages I've managed to unearth. Don't know whether the D-Bus one's related. Anyway, I'm at a bit of a loss as to what to do next so any help would be much appreciated. Let me know if I can provide any more details.

cat /etc/fstab

Re: [SOLVED] systemd fails to unmount home and temporary directory

Same problem here. It started a month or two ago.
/tmp is handled by systemd only (no line in fstab) and /home is not encrypted.

It's getting a bit annoying, I have to use Ctrl-Alt-Del to force reboot where it hangs on shutdown and then press the power button.

Re: [SOLVED] systemd fails to unmount home and temporary directory

I too have this problem and it's happening on 2 machines of mine...

following these steps from

http://freedesktop.org/wiki/Software/sy … eventually

everytime I reboot... I see the message

Failed unmounting Temporary directory
Failed unmounting /home

and it lasts for 10 seconds then reboots.... but in many cases it don't and I have to force reboot...

Been going on for weeks now

I'm going to start another thread as this one is marked as solved

Re: [SOLVED] systemd fails to unmount home and temporary directory

Just chiming in, i have 4 arch installs, this happens on only one where arch is installed on a 16 GB Sandisk Blade USB thumbdrive. Seems to only happen after a pacman -Syyu. Sometimes the reboot takes as long as 10 minutes. Ive been experiencing this for past few months on that one install.
