thanks Smith.

the web site is put in a NetApp Storage. Two SUN server use NFS to mount it.

"checkpoints" means it will save the database to /usr/local/mysql/data??? Every NDBD save the data to their own /usr/local/mysql/data?

I want to know more about "checkpoints". How to config. Anywhere I can find the infomation?

If my database is 100M for example,
(SizeofDatabase * NumberOfReplicas * 1.1) / NumbeOfDataNodes [from manual]
so each server use 55M RAM. If the usage is heavy, many "query", will this use a lot more memory? or it just around 55M? I am worrying about it will use up all my RAM......

The default mysql table "mysql" which store the user and mysql data. Do I need to change all those table to use NDBCLUSTER???

Thanks
