I hope we'll see this some day implemented. Can you comment on my first question too please? Basically i'm just curious to know if there is a way to stop and restart the rebuilding process (and change/re-create the array in between them). Btw, i read somewhere, that "--stop", then "--create --assume-clean" on an array works only on v0.9 superblocks, because v1.x overwrites existing data during create. It doesn't make sense for me - but i'm not sure -, so is this true? If not, then is it enough to use the same suberblock version for "--create" to make this work without data loss?
