ZFS's lack of recovery tools at least in the beginning were basically non existent. This is because ZFS uses a COW model with an atomic data management unit design which by it's nature addresses thing like fsck, and sudden power loss. However, things outside of a FS's control still allow corrution to happen so as UPS is just as important with ZFS as your traditional FS. Perhaps more important because the difficulty from recovering from some types of pool corruption. -- Adam Vande More _______________________________________________ freebsd-stable@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to "freebsd-stable-unsubscr...@freebsd.org"
