Hi,

I installed a NDB cluster on linux using tarball and I am able to successfully start all 4 nodes. below is the status. But when I create databases from sqlnode, they are going in to sqlnode's local datadir. they are not going in to ndb nodes. Can someone please help me. below are my cnf contents .

NOTE: I am using a custom directory structure and I used below command to bring the sqlnode up

./bin/mysqld --defaults-file=/sites/app/servers/sqlnode/etc/my.cnf --initialize-insecure --datadir=/sites/app/servers/sqlnode/data/ --basedir=/sites/app/APPS/mysql

./bin/mysqld --defaults-file=/sites/app/servers/sqlnode/etc/my.cnf --basedir=/sites/app/APPS/mysql/ --datadir=/sites/app/servers/sqlnode/data/ &


ndb_mgm> show
