fault tolerance of managment server

[ankush grover]

hey friends,

I recently configured clustering of mysql 4.1.14. There are 2 Storage Nodes ,2 Mysql nodes and 1 management server.Now I want to add one more management server so that if one management server goes down the other management server can take up the charge.

I don't want a single point of failure.How do I configure fault tolerance/High Availability of management server.

the below is the config.ini
[NDBD DEFAULT]
NoOfReplicas=2
DataMemory=400M
IndexMemory=160M
MaxNoOfAttributes=20000
MaxNoOfTables=1600
MaxNoOfOrderedIndexes=5000
MaxNoOfUniqueHashIndexes=5000
[MYSQLD DEFAULT]
[NDB_MGMD DEFAULT]
[TCP DEFAULT]
# Management Server
[NDB_MGMD]
HostName=10.0.0.1
# IP addresses of the management servers
# Storage Nodes
[NDBD]
HostName=10.0.0.2 # IP address of storage-node-1
DataDir= /var/lib/mysql-cluster
[NDBD]
HostName=10.0.0.3 # IP address of storage-node-2
DataDir=/var/lib/mysql-cluster
# Setup node IDs for mySQL API-servers (clients of the cluster)
[MYSQLD]
HostName=10.0.0.1
[MYSQLD]
[MYSQLD]
[MYSQLD]
HostName=10.0.0.4

I want to add Host 10.0.0.4 as the second management server.

Thanks & Regards
