I want to thank everyone who has provided insight into my thread about clustering MySql. I kind of just sat back and watched it develop. I learned a lot from it all.
I have been reading all of the documentation on clustering provided by Centos/Red Hat, and find I travel in circles. I read one chapter and answer a self-imposed question but I end up asking myself another.
What I really want to do is have HA for any service I run (which is mostly HTTP, MySQL, FTP, and the common things like that). I want to run that to redundant storage somewhere that is real easy to expand by just adding more hardware (server or disk drive).
I started exploring this by using the Cluster Suite as a base and then looked into each aspect of the cluster and invariably got stuck on the storage side of this. I see how I can maybe set this up originally, but the expansion just doesn't seem to be there. I don't really want to go the route of Fibre channels and ISCSI, and would prefer to use common hardware (which sort of suggests GNBD).
If anyone cares to offer suggestions, with a pretty clear explanation trail (thanks Ken Price for your link to a step-by-step), I would really like to see it, as I'm not getting anywhere with the documentation. I hope to get some hardware to play with shortly, and maybe that'll make things clearer.
I'm sure it one of those deals where once I get it done, it'll be so obvious. I just need a little kickstart to help me get there.
Thanks,
Steve Campbell
