Hmm, I'd never heard of any of those before, I'll check them out. Haven't really got an end goal, it's more of a learning curve trying to teach myself some of the fundamentals about how the kernel works, and sharing what I find. That, and IO wait / deadlocking was the bane of my existence for the entire of 2010 whilst attempting to try out technologies such as DRBD, XFS, OCFS2 in a HA environment :/ On Mon, Feb 7, 2011 at 11:19 PM, coderman <coderman () gmail com> wrote:
