[PATCH] ceph-disk: s/prefered/preferred/

[Nathan Cutler <ncutler@suse.cz>]

Hi,

Please pull the following Ceph updates from this mail.

There is not much here, just some overdue proofreading.

This patch is based on a recent merge of the jewel tree to avoid 
conflicts with a recent refactor.

Sincerely

Signed-off-by: Nathan Cutler <ncutler@suse.cz>
