通过检查盘的属性为 640
[grid@rac2 raw]$ ls -ltr
total 0
crw-r---- 1 grid asmadmin 162, 1 Jul 8 16:43 raw1
crw-r---- 1 grid asmadmin 162, 2 Jul 8 17:11 raw2

正确的属性值为660
chmod 660 raw*
[grid@rac2 raw]$ ls -ltr
total 0
crw-rw---- 1 grid asmadmin 162, 1 Jul 8 16:43 raw1
crw-rw---- 1 grid asmadmin 162, 2 Jul 8 17:11 raw2
属性值对后,创建数据库正常,前期盘的规划属性一定要设置准确。
