[linux-lvm] vgscan can not find active volume group when i add a cdrom

[Christophe Nowicki]

Hi all,

I've solved my problem, I just switched cdrom possition. 
I put the CD-ROM as secondary master and the hard drive as secondary
slave. And now everything is working :

/* dmesg output */

Strange, it isn't it? I've a link between /dev/hdc and /dev/cdrom  
does it play a role?

Thanks
