So, am I reading you (and Ulf's previous mail) correctly in that the example given in the Handbook is not expandable? volume raid10 plex org striped 512k sd length 102480k drive a sd length 102480k drive b sd length 102480k drive c sd length 102480k drive d sd length 102480k drive e plex org striped 512k sd length 102480k drive c sd length 102480k drive d sd length 102480k drive e sd length 102480k drive a sd length 102480k drive b I thought that this was the "mirror of stripes" that you describe above. > I add to my mirrors regularly, usually just to move volumes around.

Ignoring my current configuration for the moment because of the confusion caused by it, how would I expand the above example by adding 5 additional disks? Thanks for your patience with me here. I'm trying to understand how this should work. - Dimitri
