Hi,

Hi,

what to do when I modified my config.ini? I need to restart the ndb_mgmd but how? Just kill him and start him again?

Just kill and restart with new config file the ndb_mgmd.

After that do the following commands in the management client ndb_mgm> 2 restart Wait until restart is fully completed ndb_mgm> 3 restart Wait until restart is fully completed

If the change also affected the MySQL server you should at this point also restart those one at a time.

The cluster will be operational through the entire change.

Also check the manual on what changes are allowed, there are a few changes that can only be done by taking a backup, building a new cluster and installing the backup such as when adding data nodes, changing the number of replicas.

Also if you changed NoOfFragmentLogFiles you need to do 2/3 restart -I instead since you need to remove the old file system in this case to create a new one with the appropriate number of log files.

And as usual take a backup before you do all this.

What is with the nodes? Do I also need to restart every ndb node?
