What I meant is that now that --mixed isn't default, it avoids auto- halving the space due to duping the data as well (which AFAIK it used to do by default since mixed-mode treated everything as metadata, and metadata defaults are dup except on ssd), in mixed-mode. Tho now that I think of it, it's possible I'm mistaken, since I always specify single/dup/raid1/whatever, as well as mixed if I want it, choosing not to rely on the defaults, myself. Which seems a pretty wise choice, with the defaults changing over time, sometimes, as with removal of the old default mixed under a GiB, to strongly dis-recommended defaults. =:^( -- Duncan - List replies preferred.
