The other way to do it is to just pull the device, preferably with the file system unmounted. And then use it in degraded mode. I don't know if it's possible to convert a degraded volume, however. Jeez, do I write much? Disconnect the device you want removed from the volume. Mount the one you want to keep using with -o degraded.
