My understanding is that you currently cannot expand raid10.
but there are things in the works. Expansion of raid10,far
was not on the list from neil, raid10,near was. But it should be fairly
easy to expand raid10,far. You can just treat one of the copies as your
refence data, and copy that data to the other raid0-like parts of the
array. I wonder if Neil thinks he could leave that as an exersize for
me to implement... I would like to be able to combine it with a
reformat to a more robust layout of raid10,far that in some cases can survive more
than one disk failure.
best regards
