New to cluster fencing and STONITH
Hey there! I'm fairly familiar with Linux as I've been using it for a couple years now as a MySQL DBA.
The problem is that I've been asked to research and determine the best way to cluster 2 MySQL DB servers using HA (Heartbeat) and fencing with STONITH on servers that are equipped with HP ILO cards.
As mentioned before I'm a DBA so this is getting a bit deep for me. I've determined that HA basically flips around the IP and DRBD if you're using it, and apparently STONITH is deprecated in Heartbeat so you need a cluster resource manager.
Are there any good resources our there for setting this up for someone that is a little new to the process?
Replicating the MySQL database files with drbd is not the best way to go, due to data inconsistency caused by such a mechanism. MySQL has its own clustering system. You might want to have a look at http://www.mysql.com/products/database/cluster/.
