Description of problem:

When issuing a umount command you can get the following message "mount disagrees with the fstab".

This message doesn't give any usefull information about what really happens.

Here's what was the trigger of it in my install and how I fixed it :

I had this line in my fstab file

* server:/share	/share	nfs	noauto,user,defaults        0 0

but then umount gave me the not very helpfull message...

I found this doing a 'cat /etc/mtab | grep share'

server:/share/ /share nfs rw,nosuid,nodev,noexec,relatime,vers=3,rsize=32768,wsize=32768,namlen=255,hard,proto=tcp,timeo=600,retrans=2,sec=sys,mountaddr=192.168.0.1,mountvers=3,mountport=892,mountproto=udp,local_lock=none,addr=192.168.0.1 0 0

I finally understood that the PRECISE value in mtab and fstab syntaxicaly didn't match, then I changed my fstab line to this :


* server:/share/	/share	nfs	noauto,user,defaults        0 0

This time no more problem.

The error messages needs to be more verbose and explicative about what the problem is, or the mount/umount executables needs to be modified to be more aware about a simple "/" difference.

The Libc logic "strcmp(str1, str2)≠0 means different" is a bit overkill in this context and needs a better approach.

How reproducible:

always

Steps to Reproduce:
1.do not include a / at the end of a nfs mount source in fstab
2.mount
3.umount
  
Actual results:

says that the umount is not possible because "mount disagrees with the fstab"

Expected results:

understands that /share/ and /share means the same and do the umount
