The other plus is that growing linear arrays is cake. They just get added to the end of the concat, and xfs_growfs is used. Takes less than a minute. Whereas md raid0 grow means converting to raid4, then adding the device, then converting back to raid0. And further, linear grow can be any size drive, whereas clearly with raid0 the drive sizes must all be the same.
Nice! I have been learning about md arrays and have seen the details about growing operation but it's another aspect which I wasn't thinking about at first. For now I am not planning any storage but it might come handy later on.
