Jeff, Could you please expand a little? Do you mean that adding new hosts can lead to deleted data resurrection if cleanup isn't done prior to that? I would only expect this to be a potential problem if one removes nodes, since then range ownership can expand, but not with adding nodes, as then ownership can only shrink. Or am I missing something bigger? -- Alex
