OK, you're using an older LVM2/device-mapper that does not use udev to
manage the device nodes and symlinks in /dev.

Yes. Or use the alternate style I showed and only accept the PVs
belonging to the data VG.

As Lars said you may also need to rebuild your initramfs although if the
data VG doesn't contain your root file system, swap or other resources
normally set up in the initramfs this shouldn't be needed.
