Is it possible to use gmirror for a small partition on two disks and then use gstripe on the remaining disk space of those drives to create a larger stripe? I didn't think that was possible. I could be wrong however :). If that will work, that would be my best option right there. > On Thursday 24 May 2007 12:43:36 pm tradigan@newrevolutions.net wrote: >> Is it possible to use gvinum to create a striped array that contains the >> root partition?
