Description Alfredo Ferrari 2001-02-26 13:23:39 UTC
From Bugzilla Helper:
User-Agent: Mozilla/4.76 [en] (X11; U; Linux 2.2.16-3smp i686)

I am experiencing problems in unmounting partitions (only those
defined with the LABEL=... syntax) when logged as a
normal user even though they are flagged "user" in fstab.

More precisely, I can mount them with no problem, but I get a message

umount: /work mount disagrees with the fstab

everytime I try to unmount a partition which is identified by "LABEL=..."
in fstab. All partitions given in fstab with the explicit device instead
of the LABEL=... syntax mount and umount with no problem.

As root I can of course umount all partitions flawlessly. I suspect some
permission problem which shows up only for those partitions which use
the LABEL=... syntax in fstab. I do not know if it is a problem of my
machine or a general one.

I include as attachments my fstab file, the mtab file at the time I tried
to unmount as a normal user (/disk2, /disk3, /work do not unmount,
/diskmo, /diske unmount with no problem), and a file containing the error
messages, the kernel version and the version of mount I am using.

P.S. Using the glibc's (i386) and mount from wolverine does not solve the
issue (I have not yet upgraded the kernel)

Reproducible: Always
Steps to Reproduce:
1.define a partition using LABEL=.. in fstab and with user as option
2.mount that partition as a normal user
3.try to umount that partition as a mormal user

Actual Results:  The system complains 

umount: /work mount disagrees with the fstab

If root is umounting there is no problem. If the same partition is defined
in fstab using explictly /dev/... instead of LABEL=...
there is no longer any problem in umounting it as a normal user as it
should be

Expected Results:  Of course that a normal user could both mount and umount
partitions flagged with "user" regardless if they are defined thru
LABEL=... or /dev/... inside fstab

Hi, I am very disappointed to see that the bug is there in RH7.1 SeaWolf as
well. Is there any chance that this bug will ever be looked into or posting bugs
to Bugzilla is just a waste of time since it is there unassigned after two

Comment 5 Helge Deller 2001-06-11 13:06:12 UTC
problem still exists in mount-2.11c-1.rpm

Comment 6 Helge Deller 2001-06-11 15:52:51 UTC
fixed with mount-2.11e-1.src.rpm
