Bug Description
I have encountered several people who have been confused into creating some huge amount of (physical) disk partitions by the following:
"""
Preparing the Ring
The first step is to determine the number of partitions that will be in the ring. We recommend that there be a minimum of 100 partitions per drive to insure even distribution across the drives. A good starting point might be to figure out the maximum number of drives the cluster will contain, and then multiply by 100, and then round up to the nearest power of two.
For example, imagine we are building a cluster that will have no more than 5,000 drives. That would mean that we would have a total number of 500,000 partitions, which is pretty close to 2^19, rounded up.
"""

Of course, what the doc is referring to is partitions in the ring, not physical disk partitions. Each disk should have one partition - as correctly described in the install documentation fdisk commands.
I would suggest that we change the first paragraph of "Preparing the Ring" to ensure that the reader can easily determine which are disk partitions are which are partitions in the ring.
