Description Kevin Moore 2002-04-01 02:46:55 UTC
From Bugzilla Helper:
User-Agent: Mozilla/4.0 (compatible; MSIE 5.01; Windows NT)

Description of problem:
When data is written to /mnt/cdrom and then deleted and the file system is 
unmounted, the system reports that the file system is actually mounted and 
displays old information.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
Panasonic DVD-RAM LF-D311SC drive is mounted to /mnt/cdrom. Files are written 
to the media and then deleted or the disk unmounted and reformatted. 

Actual Results:  While the disk is in an unmounted state, do an "ll" command 
on /mnt/cdrom and the system seems to think the file system is actually mounted 
and displays the old contents of the media. I can also write to /mnt/cdrom as 
if it were mounted.

Expected Results:  I would not expect the system to think that a file system 
were mounted when in fact it is not.

Additional info:

Seems a little dangerous that the system may be giving me old data instead of 
what may in fact be on the media that is unmounted.

Comment 1 Elliot Lee 2002-04-15 15:54:37 UTC
Are you sure the filesystem doesn't get mounted twice or something?

Can you give me a shell script to reproduce the problem using loopback mounts?

Comment 2 Kevin Moore 2002-04-25 20:21:07 UTC
File system was not mounted twice. Have since installed the latest Rawhide 
kernel and the problem went away.
