Dear All,
I'm currently building up a HA Cluster using lastest MySQL Cluster, Heartbeat and Ha-Proxy.
Basically I already have setup everything needed an it seems to work fine. Now I've stumbled across a big problem. I dumped one database from our production server to do some failover testing on the cluster. The problem is that in order to have the db replicated on both storage nodes I have to change ENGINE in the sqldump to NDB. Once I did that and tried to restore the db I got errors saying that NDB is not capable of e.g. FULLTEXT searches etc. Googling the web shows clearly that I have to use MyISAM since NDB doesn't support it (yet???). Now I'm stuck becuase if I can't replicate a db my load-balancer (HA-Proxy) is useless since I don't have the db on both storage nodes. Once a client is switched to the other storage node there are no tables in the db. :(
Can I use on storage node with two mysqld's? The storage nodes are conntected via iSCSI to a netapp storage that is clustered so I would not really need a second storage node.
