Oracle RAC NFS挂载文件系统

oracle版本：11.2.0.4.0

操作系统:Aix 7.1

问题描述：使用NFS方式挂载文件目录到RAC的任意节点后，进行数据库备份报错如下；

ORACLE MOS查询建议如下：

RAC 

• Binaries is the shared mount points where the Oracle Home and CRS_HOME is installed.
• Datafiles includes Online Logs, Controlfile and Datafiles

* NFS mount option “forcedirectio” is required on Solaris platforms when mounting the OCR/CRS files when using Oracle 10.1.0.4 or 10.2.0.2 or later (Oracle unpublished bug 4466428)
** AIX is only supported with NAS on  AIX 5.3 TL04 and higher with Oracle 10.2.0.1 and later (NetApp)
*** NAS devices are only supported with  HPUX 11.23 or higher ONLY 

# These mount options are for Linux kernels 2.6 and above for older kernels please check Note 279393.1
