Hi, I've tried mysql cluster recently and noticed strange thing, when I tried to put the contents of service 'mysql' database into NDB cluster.
Some tables could not be put into cluster without modification since BLOB is not yet handled, so I changed all blob and text to char(255) and put all tables in mysql database to cluster, using: 'alter table XXX type=NDB' On machine where second MySQL, connected to the cluster works, I deleted mysql.* tables MyISAM files from datadir (when server was stopped) and successfully started MySQL. I noticed the following: * some tables' files were created on the filesystem after mysqld start (note there is no correspondent .MYD, .MYI files): $ ls -1 columns_priv.frm db.frm func.frm help_category.frm help_keyword.frm help_relation.frm help_topic.frm host.frm tables_priv.frm user.frm * permissions/grants for user root were dropped, so that I can not access mysql database anymore: [EMAIL PROTECTED] /var/lib/mysqlcluster/mysqldata]$ mysql mysql ERROR 1044 (42000): Access denied for user: ''@'localhost' to database 'mysql' [EMAIL PROTECTED] /var/lib/mysqlcluster/mysqldata]$ mysql -u root mysql ERROR 1044 (42000): Access denied for user: ''@'localhost' to database 'mysql' [EMAIL PROTECTED] /var/lib/mysqlcluster/mysqldata]$ mysql Welcome to the MySQL monitor.
