Painfully Slow Reboot/Shutdown

[jmadero]

Hi All,

I'm having painfully slow reboot/shutdown times for my Ubuntu media box. Running on a bit of an older machine (but still not that old), and it's taking 3-5 minutes to shutdown (no joke, never seen this before). Not sure what I can do to try to get the speeds to a more acceptable level (less than 30 seconds I think is reasonable right??)

Hi jmadero,
For me, slow shutdowns have been from a K* file in /etc/rcX.d (were 'X' is the current runlevel) taking too long to complete. If you are running VM's, they might be shutting down which could take significant time. You can watch the progress of this step and isolate the slow responder.

Also, I've read that when people have problems with power management, shutdown can take awhile to complete. I've never experienced this however

I have two drives mounted via fstab that are physically on a Win 7 machine on the network. If I don't dismount them first ( sudo umount -a ) from a terminal, shutdown/reboot is s l o w. If I do, it's very fast. This is not a solution, just an observation...
Looking for a way to automatically dismount the network drives when rebooting/shutting down.

@ImChipBrown:

I haven't done it, but it seems to me you should be able to create a /etc/init.d/K* script to do this. Since you are issuing the command before shutdown, it should be able to run very early in the shutdown sequence.

I believe that rather than the simple-to-type command you mention, it would be better to explicitly umount the drives you mean in the script.

@jmadero:

Have you investigated this suggestion? It does seem likely that a remote umount might be the culprit, you'll need to experiment with umounting it manually first.

Good Luck!
