> WAT?!  How can I mount an unpartitioned/unformatted array?  This is more direct than using a filesystem, although there would be no journalling, right?  If I were to mount my small disk for / and the unpartitioned array as /home for example.

What's he's saying is that RAID and LVM do not need partitions to work
properly. You can create a raid array on the raw(unpartitioned)
/dev/sdX devices and then create a LVM volume group using a physical
volume(PV) on a raw(unpartitioned) /dev/mdX (RAID) device.

The filesystem still needs a partition/volume but that can created
either by partitioning /dev/mdX *or* creating a logical volume in LVM.

For example, on my system at home I use RAID-6 created using
/dev/sd[b-f]. The resulting /dev/md0 acts as a physical volume for LVM
and I've created several Logical Volumes aka "partitions" for the
filesystems to reside in.

> Seems like journalling/crash recovery is pretty vital.  Could not partitioning be recommendable?

See above. You still have a partition/volume of some sort where the
filesystem is created.
