在ORACLE RAC环境中，为磁盘组扩容提示ORA信息，disk XXX contains a valid RDBMS file，如下

SQL> alter diskgroup DATA add disk '/dev/asm-disk6';
alter diskgroup DATA add disk '/dev/asm-disk6'
*
ERROR at line 1:
ORA-15032: not all alterations performed
ORA-15201: disk /dev/asm-disk6 contains a valid RDBMS file

可以使用kfod命令查看磁盘信息

[root@mhxy01 ~]# dd if=/dev/zero of=/dev/asm-disk6 bs=8192 count=2560
2560+0 records in
2560+0 records out
20971520 bytes (21 MB) copied, 1.53055 s, 13.7 MB/s

[oracle@mhxy01 ~]$ kfod status=TRUE asm_diskstring='/dev/*' disk=all

再次添加磁盘成功

SQL> alter diskgroup DATA add disk '/dev/asm-disk6';

Diskgroup altered.
