The reason is relatively easy: if my raid is read-only, it can crash and I can reassemble it without a problem, but I cannot make it read-only if the crypt-mapping is read-write. > Anyway, I think we can add this option to "resize" command perhaps. > (Resize reloads mapping, so it can switch read-only flag as well.)
