在使用NFS挂载oracle文件目录时(一般用于RAC存放各节点的归档日志)，今天遇到了类似的问题，特记录总结

适用范围

This document is relevant to all environments using Oracle Clusterware & RAC.

补充说明

The options with which the NAS systems should be mounted are described. This note does not cover the new dNFS feature that was introduced in 11g.

描述

RAC including RACone and single instance RAC

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
nfsvers and vers are identical on those OS platforms that has nfsvers. The ver option is an alternative to the nfsvers option. It is included for compatibility with other operating systems
Please note that the mount options on each of the following cells are applicable only to those type of files listed in the column heading.
For RMAN backup sets, image copies, and Data Pump dump files, the "NOAC" mount option should not be specified - that is because RMAN and Data Pump do not check this option and specifying this can adversely affect performance.

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required on Solaris platforms when mounting the OCR/CRS files when using Oracle 10.1.0.4 or 10.2.0.2 or later (Oracle unpublished bug 4466428)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

## The stated mount options for binaries are applicable only if the ORACLE HOME is shared.

Due to Unpublished bug 5856342, it is necessary to use the following init.ora parameter when using NAS with all versions of RAC on Linux (x86 & X86-64 platforms) until 10.2.0.4.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

示例
下面的示例是 aix下挂载存放oracle归档日志文件的目录
在节点2上将节点1的目录挂载
节点2
mount -o rw,bg,hard,nointr,rsize=32768,wsize=32768,proto=tcp,vers=3,timeo=600 192.24.180.81:/rac1_arch /rac1_arch

* 192.24.180.81是节点1的ip地址，/rac1_arch是节点1的归档日志文件存放目录 ,第二个 /rac1_arch是在节点2的挂载点
