Hi, looking at RHEL6.3 kernel code there must be a corruption or 
incompatibility somewhere between command line and kernel and raid1 
should definitely be recognized.

Could you first try running the `lvcreate` command with `-vvvv`, please?

I see the lvm2 package is fairly recent. What about kernel? What do 
`uname -a` and `dmsetup targets` say?
