Specify how metadata must be spanned across the devices specified. Valid
values are raid0, raid1, raid10, single or dup. Single device will have dup
set by default except in the case of SSDs which will default to single. This is
because SSDs can remap blocks internally so duplicate blocks could end up in the
same erase block which negates the benefits of doing metadata duplication.
