Is it possible and useable to use ZFS as a GMIRROR replacement where one disk is detached most of the time? I use an external (Firewire) disk to mirror my system disk. It gets only attached once a week for synchronizing. That way, I get a consistent 1:1 mirror of the system disk. Does ZFS cope with detached drives as well? And can the detached drive function on its own? (Sometimes, I use this firewire drive as a portable disk to supplement my laptop storage). Thanks!
