[systemd]Add delay before shutdown

Ypnose · 2013-06-04 13:01:50

Hi,
Since 3.9.x kernels, sometimes when I turn off my computer, I can see two lines about ETX4 fs (they're the last lines), just before the computer shuts down.
journalctl doesn't show those lines.
My messages aren't related to this "bug": https://bbs.archlinux.org/viewtopic.php?id=162905
I would like to see what the lines said, but it's too fast. I tried to debug as described in this link: http://www.freedesktop.org/wiki/Softwar … /#index3h2 but it didn't work.

Could you tell me how can I add a little delay?

Have you tried using halt instead of poweroff / reboot and pausing the output with Ctrl-s? You can unpause with Ctrl-q (to pause it immediately again so you can view another screenfull).
You have to have fast fingers and I'm not sure if it works if you have 'stty -ixon' in your .bashrc as it disables the interrupt data flow function of Ctrl-s command.

I didn't know those shortcuts. Indeed, I'll have to be very fast.
Thank you. I will report back what I find.

Hum, I had the warnings again (three times) and I was unable to stop the shutdown. It goes too fast.
Any ideas?

Just use halt instead of poweroff.
Then you can write down / take a photo of the warnings.
Then reboot manually with the power switch.

Unless there are too many of them and they scroll by.

@Ypnose
You can fiddle with 'quiet' setting and its friends to pick the loglevel that displays the warnings you're looking for but less other info.

Try creating a shutdown log: http://freedesktop.org/wiki/Software/sy … /#index2h1

add "ash" to /run/initramfs/shutdown, just before poweroff/reboot commands. (you need shutdown hook on mkinitcpio).

Thank you guys. If I have another warnings, I'll try what you suggested me.
