Description Pavel Alexeev 2011-05-06 14:12:45 UTC
Description of problem:
[pasha@vbox smolrg]$ mount /mnt/net/y
[pasha@vbox smolrg]$ 
[pasha@vbox mnt]$ umount /mnt/net/y 
umount: /mnt/net/y mount disagrees with the fstab

/etc/fstab related record:
//192.168.100.199/updater /mnt/net/y cifs users,noauto,guest,uid=500,gid=500,file_mode=0666,dir_mode=0777,iocharset=utf8 0 0

I think it is known problem with available patch. Please look at: https://bugs.launchpad.net/ubuntu/+source/util-linux/+bug/99437

Version-Release number of selected component (if applicable):
$ rpm -qf `which mount`
util-linux-2.19-4.fc15.i686

How reproducible:
Always.

Comment 1 Karel Zak 2011-05-09 07:33:36 UTC
The problem is that fstab does not match with mtab, right? For example:

fstab:                //foo.com/path
mtab (/proc/mounts):  //foo.com/path/

The umount(8) command (for non-root users) requires that the first field in fstab matches with the first field from mtab (or /proc/mounts).

The mount.cifs should not add the extra '/' to the end of the source path or cifs docs should be updated and the '/' should be required in all fstabs.

Comment 2 Jeff Layton 2011-05-16 11:00:42 UTC
Yep, this was actually fixed in "mainline" cifs-utils a couple of weeks ago by just having it pass the "device" string from userspace to the kernel directly (instead of trying to reconstruct it).
