裸设备建磁盘组报错，请教原因，环境用的是推出来的，裸设备磁盘不是用loop,用的是虚机上增加的盘
报告如下错误，提示找不到路径下有磁盘：
SQL> create diskgroup newdata normal redundancy
2 failgroup newdata_group_1 disk '/dev/raw/raw1' name raw1,'/dev/raw/raw2' name raw2
3 failgroup newdata_group_2 disk '/dev/raw/raw3' name raw3,'/dev/raw/raw4' name raw4
4 ;
create diskgroup newdata normal redundancy
