And then add all the other stuff, like scenarios where half of your RAI= D is "somewhere" on the network via nbd, iSCSI or whatever and all the other possible stackings... Definetely user-space material, and partly because it /needs/ to have the input from the volume managers to do the sane things. The point about this implying that the superblock parsing/updating logi= c needs to be duplicated between userspace and kernel land is valid too though, and I'm keen on resolving this in a way which doesn't suck...
