You can mirror any GEOM providers, which includes disks, slices, partitions, encrypted providers, RAID0/RAID3 devices, ZFS volumes, GEOM gate devices, and more. Anything you can probe with diskinfo(8) can be mirrored (and used for other GEOM classes too). It's more than that. You can even mix providers from different GEOM classes, eg: lcf:root:~# gmirror status Name Status Components mirror/foo COMPLETE ad4 ad5s1 ad6s1a ad7.eli stripe/bar raid3/baz ggate0 zvol/tank/vol That's GEOM, my friend:) --=20 Pawel Jakub Dawidek http://www.wheel.pl pjd@FreeBSD.org http://www.FreeBSD.org FreeBSD committer Am I Evil?
