Hi All, We are thinking about trying out a 2-way or 3-way mirror for a filer = based on FreeBSD, with HAST and ZFS. With traditional ZFS for expanding capacity in what I think of as a = traditional 'stripe over mirrors' - it is quite easy by replacing say = 500GB disks one at a time with 2TB in a given mirrored unit. How does this work if we are using hast? Is it transparent? Is it = impossible? Is it possible to do and still be 24x7 with a little bit of = command line work? Thanks, - Mike DeMan
