昨天，使用openfiler創(chuàng)建nas存儲(chǔ)系統(tǒng)，并安裝oracle軟件，前面一切順利，到創(chuàng)建數(shù)據(jù)庫時(shí)報(bào)ora錯(cuò)誤，原來使用nfs安裝oracle數(shù)據(jù)庫時(shí)，mount選項(xiàng)有特殊要求，整理總結(jié)如下，以備查：

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required on Solaris platforms when mounting the OCR/CRS files when using Oracle 10.1.0.4 or 10.2.0.2 or later (Oracle unpublished bug 4466428)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

Due to Unpublished bug 5856342, it is necessary to use the following init.ora parameter when using NAS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.

按照上面所示，設(shè)置參數(shù)，結(jié)果仍然報(bào)錯(cuò)ora-27086,錯(cuò)誤信息如下：

[oraten@yue ~]$ oerr ora 27086

27086, 00000, "unable to lock file - already in use"

// *Cause: the file is locked by another process, indicating that it is

// currently in use by a database instance.

// *Action: determine which database instance legitimately owns this file.

重啟openfiler，成功解決問題，看來是之前mount不當(dāng)導(dǎo)致在openfiler端有鎖一直沒有釋放。

雖然oracle支持nfs，但使用nfs的情景比較少，多數(shù)使用nfs來備份數(shù)據(jù)庫或者存放歸檔

總結(jié)
