Interesting. It looks like /proc is unmounted. That didn't happen in
my tests.
If you can run an experiment for me, there are a couple of tests you can
make to check this out. The stop portion of the script now reads:
stop)
# Don't unmount tmpfs like /run
log_info_msg "Unmounting all other currently mounted file systems..."
umount -a -d -r -t notmpfs,nosysfs,nodevtmpfs >/dev/null
evaluate_retval
# Make all LVM volume groups unavailable, if appropriate
if [ -x /sbin/vgchange ]; then /sbin/vgchange -an; fi
;;
First, try moving the vgchange line to right before the umount command.
The second test would be to use the current script but change the line:
-t notmpfs,nosysfs,nodevtmpfs
to
-t notmpfs,nosysfs,nodevtmpfs,noproc
I suspect that cheange one will work. When testing, be sure to add back
the vgchange symlink.
The second change would be preferable because I am thinking of moving
the vgchange command to the swap script in case one or more swap areas
are LVM based.
OTOH, in /etc/rc.d/rc{0,6).d/ we now have S70mountfs and S80swap. I'm
thinking that turning off swap before unmounting might be appropriate.
That is, change the symlink names there to S65swap.
