From the zpool manpage: In order to take advantage of these features, a pool must make use of some form of redundancy, using either mirrored or raidz groups. While ZFS supports running in a non-redundant configuration, where each root vdev is simply a disk or file, this is strongly discouraged. A single case of bit corruption can render some or all of your data unavailable. Is this supposed to mean: "ZFS is more fragile than most. If you don't use redundancy, one case of bit corruption will destroy the filesystem" Or: "Hard disks explode often. Use redundancy."
