Documentation on recovering from split-brain situation

[toby.corkindale at strategicdata.com.au (Toby Corkindale)]

Hi,
I'm trying to find official documentation that describes the procedure 
for recovering from a split-brain situation with replicated volumes.

I can find various posts on the mailing list that refer to the version 
2.x series, but nothing good for 3.x.

Can anyone point me in the right direction?

Thanks,
Toby
