Does this mean it's considered accepted/acceptable? In which case, the fact that I'm using a 2.6.15 kernel and mdadm 1.12.0 (June 2005) (is that version number possibly right?) suggest I need to do a little tool updating so I can try this out. I presume that I can upgrade mdadm and then do the grow - or do I need to upgrade and rebuild the array with the upgraded tool before I can use the grow option? How much risk do I have of data loss doing this?
