Hi

Anyone experienced in DRBD

Is this a CentOS question, or a data base language question? What mailing-list or news group is the best choice for this question?

...

ls it good in using mysql redundant?

This is *clearly* a database-oriented question, not a question of (e.g.) which versions of DRDB or MySQL is found on CentOS 5.5 vs CentOS 5.6, and what problems arise from migrating versions on a CentOS platform.

...

What is it best to use?

Why brain not work? Several times now, you have asked questions, and each time you get (politely) sent to some other list. You continue here (which is not bad) asking questions that belong elsewhere (which is annoying) without learning from us to ask (here) questions that have anything to do with CentOS at all (and that's bad).

...

Thank you

Please bring CentOS questions here, please go elsewhere with others.

DRBD is closer to an OS-related topic than a database... You could go to the HA-Linux list, but the advice that you'll get there is to use newer versions of things than you'll find in Centos.

I use DRBD to keep whole servers redundant ... one of the things it keeps redundant is mysql.

If the machine was only a database server I would likely do it differently ... but it does work with minimal downtime (the time required to start the service on the other machine).

Depends on your goal ... what DRBD is great at is replicating all the services on a server to fail over to another machine if server 1 dies for some reason.

If that is what you are looking for it will work OK. If you would like some load balancing and other stuff too, DRBD is not what you are looking for.
