Description Need Real Name 2006-10-03 20:54:56 UTC
Description of problem:
Multisession DVDs produced by growisofs cannot be mounted on an IDE drive 
because of a kernel bug. The same DVDs can be mounted when the IDE drive is in 
ide-scsi emulation. Please fix this.

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

How reproducible:
Some documentation is found in /usr/share/doc/dvd+rw-tools-5.21.4.10.8-
4/index.html...

"Linux kernel 2.6 users might experience ... http://marc.theaimsgroup.com/?
l=linux-kernel&m=108827602322464&w=2 ... problems
mounting multi-session media with last session starting beyond
2.2GB boundary. As fast-acting remedy I can suggest to route your unit
through ide-scsi. The way it was under 2.4. Even though it's declared
unsupported it actually still works in 2.6 (I for one still use it)."

Steps to Reproduce:
1. Burn a DVD with over 2GB of data (growisofs -Z /dev/cdrom ...)
2. Add data (growisofs -M /dev/cdrom)
3. Attempt to mount to see the error (mount is successful with ide-scsi kernel 
parameter).
  
Actual results:
[root@devoi ~]# mount /dev/hdb /cdrom
mount: block device /dev/hdb is write-protected, mounting read-only
mount: wrong fs type, bad option, bad superblock on /dev/hdb,
       or too many mounted file systems

Additional info:
I am running this test from a supported system; the system ID is: ID-1006241967.

I wasn't able to reproduce this with the latest RHEL-4 kernel. Can you confirm if
this problem still exists in 4.5 kernel?
Thanks

Yes, this seems to be fixed using the 2.6.9-55.ELsmp kernel.

Comment 4 Aristeu Rozanski 2007-05-30 20:09:43 UTC
Good. I'll close this ticket, but feel free to reopen if you manage to reproduce
it again.
