今天把一个rac的数据重启时遇到了如下错误，提示找不到一个叫FGDG的磁盘组资源：
[grid@srcbdb1 ~]$ srvctl start database -d dcdb
PRCR-1079 : Failed to start resource ora.dcdb.dbCRS-2640: Required resource 'ora.FGDG.dg' is missing.
改磁盘组的确不存在，之前删除掉了，而且使用crsctl -t -v查看资源组时的确没有看大：
[grid@srcbdb1 ~]$ cs

因此怀疑是之前删除该磁盘组后，Database资源的配置信息没有被更新，查看一下database资源的配置发现：

在database的启动和停止的关联资源中的确有FGDG磁盘组资源，而这是不存在的，于是使用如下命令修改database关联的asm磁盘组
[grid@srcbdb2 ~]$ srvctl modify database -d dcdb -a "DATA,SFRA"
