zfs discuss - Jan 2008 - Remove a mirrored pair from a pool

Hi, I had a question regarding a situation i have with my zfs pool

I have a zfs pool "ftp" and within it are 3 250gb drives in a raid z
and 2 400gb drives in a simple mirror. The pool itself has more than 400gb free
and I would like to remove the 400gb drives from the server. My concern is how
to remove them without causing the entire pool to become inconsistent. Is there
a way to tell zfs to get all data off the 400gb mirror so the disks can safely
be removed?

Thanks

Unfortunately you''ve got to manually put data somewhere, re-create the
pool and put data back.

on-line removing of disks is coming...
