Hi all,
I'm currently thinking about similar configurations, and (also for cost
reasons :-) am also thinking about GNBD with two standard servers as a
"poor man" redundant storage - but I'm wondering if that gives enough
performance for running databases (in my case Oracle) on top of it. The
configuration I'm thinking about would be two current Dell servers with
hardware RAID 10 and connected by a dedicated 1 GBit crossover-cable,
running both the cluster software and Oracle.
Does anyone use this in "real-World" scenarios and has some practical
experience with it?
Best regards,
__

Subject: Expandable network storage
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
