how to: automatically umount cifs partitions

[bYOndo]

There is a very simple reason why you cannot simply move umountnfs to S17: What about people who load system directories or home directories from a network share? unmounting those at S17 is too soon. There may still me applications running that use them.

By the way, you said the script doesn't always work. Which one? The mountcifs script posted by the creator of this thread? Or the umountcifs I posted a couple of posts above? They both work in very different ways.

Kanji was right; I experienced this behaviour:

On 7.04: the first post script worked for me without any other modification
On 7.10: the first post script did not work, dunno why, but Kanji solution worked (but I don't know if it would work without first post script, that I've already installed before modifying S30)

Anyway, it seems to cause no problem w/ my system, so thanks and cheers

All,

I scripted the install using the code provided by the brilliant folks earlier in the post. Just thought i'd share this for the lazy fellows like me!

Just extract and give it permissions to execute.

why all the trouble when you can just put the mount command into /etc/rc.local files? This file will be executed last during bootup. It works for my smbfs mount.

The following two commands should take care of unmounting Samba shares and other virtual filesystems before a shutdown or reboot. They must be run as root; prefix them with "sudo" if you haven't set up your root account:

ln -s /etc/init.d/umountnfs.sh /etc/rc0.d/K15umountnfs.sh
ln -s /etc/init.d/umountnfs.sh /etc/rc6.d/K15umountnfs.sh

Unmount Samba filesystems before shutdown or reboot.

Hopefully, this will avoid the need to download and install a separate script, as some other people have suggested. All the tools you need are already built into the Debian/Ubuntu init system.

I just did this:

sudo nano /etc/init.d/umountnfs.sh

#! /bin/sh
#
# umountnfs.sh	Unmount all network filesystems.
#
PATH=/sbin:/bin:/usr/sbin:/usr/bin

# Write a reboot record to /var/log/wtmp before unmounting
halt -w

# Ensure /proc is mounted
test -r /proc/mounts || mount -t proc proc /proc

echo "Unmounting remote filesystems..."

#
# Read the list of mounted file systems and -f umount the
# known network file systems.  -f says umount it even if
# the server is unreachable.  Do not attempt to umount
# the root file system.  Unmount in reverse order from
# that given by /proc/mounts (otherwise it may not work).
#
unmount() {
	local dev mp type opts
	if read dev mp type opts
	then
		# recurse - unmount later items
		unmount
		# skip /, /proc and /dev
		case "$mp" in
		/|/proc)return 0;;
		/dev)	return 0;;
		esac
		# then unmount this, if nfs
		case "$type" in
		nfs|smbfs|ncpfs|cifs) umount -f "$mp";;
		esac
	fi
}

unmount </proc/mounts

I just added "|cifs" of the types that it should unmount and changed the symlinks in /etc/rc0.d and /etc/rc6.d from S31umountnfs to K15umountnfs. Works like a charm! (Don't forget "sudo chmod +x /etc/init.d/umountnfs.sh")

It worked for me. I prefer to create some symbolic links instead of creating/modifying files, so I tried your solution; I was inspired

Thank you Max Durden. Your script worked beautifully. The implementation was pretty an 'I just believe' episode, as I really don't understand the bootup and shutdown sequence nearly as well as I should. Hopefully, someone will incorporate a fix to the distribution soon so the user isn't forced to the command line. Like it or not folks, it's the only way you'll ever pry the average computer away from Micro$oft Window$.

This link doesn't seem to work for me, is this a temporary issue?

EDIT: was obviously temporary, is now working. Thanks wyleyr.

In Gutsy at least, there are already links to these files in these directories, they just start with S31 rather than K15. Tidiest option is just to change their names. I did it using "gksudo nautilus" and browsing to the directory.

veloce's renaming solution seems to work in Hardy beta too.

BTW, don't use gedit if you are editing files on network shares. I kept thinking I wasn't setting up my shares correctly, but the problem was in gedit all along.
