Try disabling apparmor. There seems to have been a regression in the apparmor
profiles and this may be biting you. You might also check that the smb/cifs
service is set to start at boot. In ll.2 it was still called smbfs but this
may have changed to something like cifs as smbfs is obsolete.

There are no guarantees here as I've not yet installed 11.4.

If smbd is off, then Samba client is off too. Here's the bug report, I think it's diagnosed now and the fix is on its way, but it's not here yet, so disable AppArmorr until the update arrives: https://bugzilla.novell.com/show_bug.cgi?id=666450

I don't know if that's causing your issue, but it's a strong candidate.

Also, goto Yast --> System --> Runlevels --> cifs and toggle it to "on" [see the 11.4 release notes, this too has changed from 11.3]. I think this cifs daemon is a bit of a dud when it comes to entries in fstab, likely it works for entries in smbfstab, but I'm not clear on that, havent tested it myself.

Okay I write the results down as I execute them. Note; the shares are mounted and after every step I try to unmount them.

Toggle "cifs" on (it was off)

Turn off apparmor

Start rcsmb

fire@a3800:/etc> sudo /usr/sbin/rcsmb start
root's password:

(I have to reboot an come back in a moment, the laptop is heating up fast. The fan is not working after it went to sleep... )

[Fire11]

Al settings have "survived" the reboot except "rcsmb".

fire@a3800:~> sudo /usr/sbin/rcsmb status
root's password:
Checking for Samba SMB daemon                                                               unused

fire@a3800:~> umount ~/Server/public
umount: /home/fire/Server/public mount disagrees with the fstab

Result > user still can't unmount.

It was worth to try but the problem lies elsewhere. I already stated that there is the change of /etc/mtab in openSUSE 11.4. It's is not a file anymore but a symbolic link to /proc/self/mounts and according to other fora this gave the same issue in the past. (and still is...)

I can positive confirm this. If the link is replaced by an empty file and you mount a share, than the share is written to the file. Unmounting the share (as user) does work with the "real" mtab. After reboot this change is gone but it is no real solution anyway...

[Fire11]

Found this info in the mount manpage...

It is possible to replace /etc/mtab by a symbolic link to /proc/mounts, and especially when you have very large numbers of mounts things will be much faster with that symlink, but some information is lost that way, and in particular using the "user" option will fail.

Don't forget to set rcnmb and rcsmb to on in Yast --> System --> Runlevels

All I can suggest now is a bug report.

[Fire11]

I forgot about "rcnmb" and set it by commandline. ("rcnmb" and "rcsmb" are not available in Yast --> System --> Runlevels.) But again, no joy.

So, perhaps it is a bug or just me using the commands wrong. I am no programmer and not sure how to report a bug or check if it is already reported...I go and figure it out...

Thanks for the support so far, it is greatly appreciated!

[swerdna]

I was unclear: In Yast's runlevels GUI, set nmb and smb to on. This will cause the daemons to switch on at boot time.

[Fire11]

I placed the "bug" at bugzilla=679949
From the first reaction it seems to be an issue in cifs.utils v4.6

@swerdna, I enabled smb and nmb the right way, but it does not change the unmounting as user issue.
