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.

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.
