Even if you put an empty CD-ROM or DVD into the drive and run
vgscan -v -v -v 2>&1 | grep cdrom ?

Then we must be using different lvm versions.

OK, that are my filters now:

    filter = [ "r|/dev/hdb|" ]
    filter = [ "r|/dev/hdc|" ]
    filter = [ "r|/dev/cdrom|" ]
    filter = [ "r|/dev/cdrom1|" ]
    filter = [ "r|/dev/cdrom*|" ]
    filter = [ "r|/dev/cdrom.*|" ]

I have two DVD writers /dev/hd[ab] /dev/cdrom and /dev/cdrom1 are
softlinks to them.
vgscan still access them both.

Could anyone who knows the code comment on this?
Looks like I will be going to read it.

Thanks,
Chris
