June 12, 201313 yr Author So the md-mod has crossed the line into knowing things that it shouldn't be knowig about. That indicates some messy software design. You know what they say about making assumptions right? The unraid driver is file system agnostic. What it doesn't support is "direct io" (this is by design at present time).
June 12, 201313 yr Sorry if my post could have contributed for wrong assumptions, and thanks for the clarification on it Tom.

Pardon me if I don't quite understand, where does the direct IO come into play here? ext3,ext4 do they do direct IO?

Now I understand. Ok thanks for clarifying that.
June 12, 201313 yr Author The unraid driver is file system agnostic. Is it also partition agnostic? Will it work with the raw block devices? Yes.

My thinking was along the lines that it may make your life many times easier if you abandon partitions altogether. There are many reasons why it's not good to do that; here's one: you lose interoperability with other systems. Hey let's end this discussion in this thread, because it's supposed to be about a specific issue.
