In the process you describe, you also lose 4GB to parity out of your total of 10GB, don't you? I'm not sold on the whole add-more-stripes idea. I want to minimize cost while maximizing capacity, and have a slim margin of fault tolerance. Speed doesn't matter much either since it's mostly streaming media on there.
I think I'll have to wait for code completion on the expansion trick. --Bart On 23/12/2007, EchoB <echobinary at gmail.com> wrote: > I believe there is a plan for expansion by adding devices to a RAID-Z - > I was asking this same question a year ago.
