[CentOS] lvm and /dev/cdrom: open failed: No medium found

Hi,

every lvm command gives one line with:
/dev/cdrom: open failed: No medium found

I looked at
https://bugzilla.redhat.com/show_bug.cgi?id=431901

and changed filter in /etc/lvm/lvm.conf to
filter = [ "r|/dev/cdrom|", "a/.*/" ]

then deleted cache /etc/lvm/cache/.cache

This seems to help, but after a while the message reappears.

Is there a way to get rid of it, because I'm making use of lvm with 
snapshots very often?

Rainer
