Reboot always causes forced FS check.

[vexer]

Every time I reboot, I get a /dev/hdc1 was not cleanly unmounted, check forced. issue.
I installed Backtrack 3 final onto my Acer Aspire One (8gb SSD version). The drive has ext2 as
it's filesystem and everytime I figure the issue is that everytime I reboot, when it tries to unmount
/, it gives me the message that / is busy, tries to remount as read only, only to get / is busy again.

Anyway of fixing this issue?

After a little thinking, I figured that since the device was busy, it was probably caused by some
process not dieing properly. I looked at the shutdown manpage and found that if I use
"shutdown -nr" to reboot, then the drive would remount cleanly after reboot.

Is there a way to see what processes are still alive right before a reboot?

I'm having a similar problem with a new ext3 partition mounted to my system always being busy when I try to shutdown my AAO...

I found this line of code from ubuntu forums and used it to isolate my problem, you'll have to login using 'su -' to use this:

shutdown -P now >> /var/log/shutdown.log 2>&1

"now" is the time so you could put 1 for 1 minute and so on, "var/log/shutdown.log" is the location of the log.

It'll log the shutdown process, it should help you isolate your problem.
I haven't of yet found a solution to my "mount: / is busy", most solutions seem to be related to evms that is used by ubuntu distros.
Hope it Helps.

If you look at the shutdown script:

cat /sbin/shutdown

You'll see that if -r is used (to reboot), then the hidden file /.autofsck is removed when a shutdown is performed. I assume that if anything else is used other than the -r option, this file is not removed and this is forcing a fsck on the next boot. So manually renaming or removing /.autofsck before shutting down, should prevent this from happening. On the next boot however, that hidden file will be created again, I believe. I don't know why Acer is doing it this way, touching a .autofsck everytime the system boots up?

Cheers.
