It was indeed the symlink, although not from hdb to cdrom, but from
cdrom to hdb. Removing this symlink (or commenting out the filter
option in lvm.conf) solved the problem.

CDRom has only been present for installation, and afterwards swapped
for extra disk. Symlink however isn't updated.

Another remark: although cdrom are filtered (and thus not allowed for
LVM), no warning/error messages appear. Wouldn't it be useful if LVM
checks this and shows warning/error messages or even exits during
creation?
