Comment 1 Thorsten Kukuk 2006-01-27 09:44:05 UTC 
What is the content of /etc/mtab?

linux:~ # cat /etc/mtab

Comment 3 Dr. Werner Fink 2006-01-30 09:45:20 UTC 
IMHO also the actual mounted devices would be
help therefore please provide the content of
/proc/mounts.
Comment 4 Andreas Klein 2006-01-30 09:49:52 UTC 
Se initial comment for cat /proc/mounts output. The devices are listed there.
Comment 5 Andreas Schwab 2006-01-30 10:09:40 UTC 
Only /etc/mtab matters.
Comment 6 Andreas Klein 2006-01-30 13:13:00 UTC 
(In reply to comment #5)
> Only /etc/mtab matters.

Why should a mounted filesystem not show up in the output of df?
Running du -sh is not  really an option to find out how full the filesystem is.
Comment 7 Andreas Schwab 2006-01-30 13:33:23 UTC 
Because /etc/mtab is the authoritative database.
Comment 8 Andreas Klein 2006-01-30 16:22:38 UTC 
Then the /etc/mtab is not correct and this should be fixed. The filesystem is really mounted as you can see from the /proc/mounts output. So it should show up in /etc/mtab, and if it does not, this is bug, isn't it?
Comment 9 Christian Boltz 2006-01-30 20:57:38 UTC 
Maybe this bug is related to bug #146192
Comment 10 Dr. Werner Fink 2006-01-31 09:23:03 UTC 
This sounds reasonable.  Whereas df only reads /etc/mtab and does its
job, the mount program also writes /etc/mtab.  Maybe there is a bug
in mount its selfs or the behaviour is caused by an `-n' option in
one of the boot scripts (-n for not updateing /etc/mtab).
