database upgrade

当部署或是升级中 with the message "database version mismatch", upgrading existing DB with  the "onedb" command 或是指定任何版本的sqlite or mysql

在最后的OpenNebula4.4中,你可以运行"onedb upgrade -v"解决oned.conf配置中可能存在的冲突;

examples:

$ onedb upgrade -v --sqlite /var/lib/one/one.db

$ onedb upgrade -v -S localhost -u oneadmin -p oneadmin -d opennebula

具体one CLI(command line interface)http://docs.opennebula.org/stable/user/references/cli.html#cli

5,数据库升级完成以后用onedb fsck检测数据系统的一致性

$ onedb fsck -S localhost -u oneadmin -p oneadmin -d opennebula
