問題描述：使用NFS方式掛載檔案目錄到RAC的任意節點後，進行資料庫備份報錯如下；

ORACLE MOS查詢建議如下：

In the table below

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required on Solaris platforms when mounting the OCR/CRS files when using Oracle 10.1.0.4 or 10.2.0.2 or later (Oracle unpublished bug 4466428)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

Due to Unpublished bug 5856342, it is necessary to use the following init.ora parameter when using NAS
with all versions of RAC on Linux (x86 & X86-64 platforms) until 10.2.0.4. This bug is fixed and included in 10.2.0.4 patchset.
