 nfs (samba, cifs): getting shares to umount @ shutdown |
|
This is NOT very elegant, but I used two ubuntu scripts: one in the /etc/init.d/ and one in /lib/init.
The issue, if I mounted shares in terminal and forgot to umount them, then the machine would hang and not shut down. I knew this was an issue with earlier 'buntus so I assumed it was the same issue.
Pnethood is a great too for mounting shares, and might solve this issue BUT if I mounted shares that way, the mounted folders were invisible to any applications except file managers and wine programs (how odd, but I get this on two machines running two different puppies.
I modified "umountnfs.sh" slightly as when I ran it, there were was an fstab command in the file, and the file needed to call another one in /lib/init. There is no /lib/init in puppy so I created it.DON'T FORGET TO MAKE THESE TWO FILES EXECUTABLE.
Put this in /etc/init.d and name it umountnfs
| Code: | #! /bin/sh
### BEGIN INIT INFO
# Provides: umountnfs
# Required-Start:
# Required-Stop: umountfs
# Should-Stop: $network $portmap nfs-common
# Default-Start:
# Default-Stop: 0 6
# Short-Description: Unmount all network filesystems except the root fs.
# Description: Also unmounts all virtual filesystems (proc, devfs,
# devpts, usbfs, sysfs) that are not mounted at the
# top level.
### END INIT INFO
PATH=/sbin:/usr/sbin:/bin:/usr/bin
KERNEL="$(uname -s)"
RELEASE="$(uname -r)"
. /lib/init/vars.sh
. /lib/lsb/init-functions
case "${KERNEL}:${RELEASE}" in
Linux:[01].*|Linux:2.[01].*)
FLAGS=""
;;

;;
esac
do_stop () {
# Write a reboot record to /var/log/wtmp before unmounting
halt -w
# Remove bootclean flag files (precaution against symlink attacks)
rm -f /tmp/.clean /var/lock/.clean /var/run/.clean
#
# Make list of points to unmount in reverse order of their creation
#
exec 9<&0 </etc/mtab
DIRS=""
while read -r DEV MTPT FSTYPE OPTS REST
do
case "$MTPT" in
/|/proc|/dev|/dev/pts|/dev/shm|/proc/*|/sys|/lib/init/rw)
continue
;;
/var/run)
continue
;;
/var/lock)
continue
;;
esac
case "$FSTYPE" in
nfs|nfs4|smbfs|ncp|ncpfs|cifs|coda|ocfs2|gfs)
DIRS="$MTPT $DIRS"
;;
proc|procfs|linprocfs|devfs|devpts|usbfs|usbdevfs|sysfs)
DIRS="$MTPT $DIRS"
;;
esac
case "$OPTS" in
_netdev|*,_netdev|_netdev,*|*,_netdev,*)
DIRS="$MTPT $DIRS"
;;
esac
done
exec 0<&9 9<&-
if [ "$DIRS" ]
then
[ "$VERBOSE" = no ] || log_action_begin_msg "Unmounting remote and non-toplevel virtual filesystems"
umount $FLAGS $DIRS
ES=$?
[ "$VERBOSE" = no ] || log_action_end_msg $ES
fi
}
case "$1" in
start)
# No-op
;;
restart|reload|force-reload)
echo "Error: argument '$1' not supported" >&2
exit 3
;;
stop|"")
do_stop
;;
*)
echo "Usage: umountnfs.sh [start|stop]" >&2
exit 3
;;
esac
:
|
Then create folder /lib/init and put this file there (call it var.sh):
| Code: | #
# Set rcS vars
#
[ -f /etc/default/rcS ] && . /etc/default/rcS || true
# check for bootoption 'noswap' and do not activate swap
# partitions/files when it is set.
if [ -r /proc/cmdline ] && grep -qw 'noswap' /proc/cmdline ; then
NOSWAP=yes
else
NOSWAP=no
fi
# Accept the same 'quiet' option as the kernel
if [ ! -e /proc/cmdline ] || egrep -qw 'quiet' /proc/cmdline ; then
VERBOSE="no"
fi
# But allow both rcS and the kernel options 'quiet' to be overrided
# when INIT_VERBOSE=yes is used as well.
[ "$INIT_VERBOSE" ] && VERBOSE="$INIT_VERBOSE" || true
|
Lastly, call the file in /etc/rc.d/shutdown
I put this near the top of the file, as the first command right after the intro commented lines:
/etc/init.d/umountnfs
