It looks okay to me. I think your vgcreate /dev/cdrom error messages are down to a non-critical bug in LVM, at any rate others have seen them and under different Linux distros. But I can't comment about the lvcreate mlock messages. Going back to your original posting I believe it is advisable to create your swap LV with "lvcreate -C y" so that it has a contiguous allocation policy. (Other LVs however shouldn't normally have this.)
