[linux-lvm] pvscan fails

[Todd Troxell]

Hello,

I'm having trouble setting up physical volumes.

caffeine:~# pvcreate /dev/hdd1
pvcreate -- physical volume "/dev/hdd1" successfully created

caffeine:~# pvscan
pvscan -- reading all physical volumes (this may take a while...)
pvscan -- ERROR "pv_read(): read" reading physical volumes

After looking at debug messages, I think it is related to my 
ide cdrom (/dev/hdc).

Does this seem to be the case?  Is there a way to ignore /dev/hdc?

(attached is output from pvscan -d) (2.2.18, lvm 1.0.4)

p.s. please cc:
