ACFS-9459: ADVM/ACFS is not supported on this OS version

**環境：**RHEL 7.3 + Oracle 12.2.0.1 RAC **現象：**acfs資源狀態不正常，asmca圖形也沒有acfs相關內容，沒法使用acfs。

• 1.具體現象
• 2.定位bug
• 3.解決問題

<h1 id="1">1.具體現象</h1> 使用crsctl stat res -t -init查詢，ora.drivers.acfs是OFFLINE狀態：

$ crsctl stat res -t -init
--------------------------------------------------------------------------------
Name           Target  State        Server                   State details       
--------------------------------------------------------------------------------

      1        ONLINE  OFFLINE                               STABLE
--------------------------------------------------------------------------------

使用lsmod|grep oracle查詢，沒有acfs內容：

$ lsmod|grep oracle
oracleadvm            776830  1 
oracleoks             654476  1 oracleadvm

嘗試重裝acfs，也會在卸載時就報錯不支持：

# /u01/app/12.2.0/grid/bin/acfsroot uninstall
ACFS-9459: ADVM/ACFS is not supported on this OS version: '3.10.0-514.el7.x86_64'

<h1 id="2">2.定位bug</h1> 確認OS內核版本：

[root@db90 ~]# uname -a
Linux db90 3.10.0-514.el7.x86_64 #1 SMP Wed Oct 19 11:24:13 EDT 2016 x86_64 x86_64 x86_64 GNU/Linux
[root@db90 ~]# cat /etc/redhat-release 
Red Hat Enterprise Linux Server release 7.3 (Maipo)

結合MOS最終匹配定位是Bug 25078431致使。

<h1 id="3">3.解決問題</h1> 我這裏選擇應用最新的PSU（其中ACFS補丁集包含了25078431這個補丁），開始應用補丁時遇到一個問題以下：

[root@db90 grid]# /u01/app/12.2.0/grid/OPatch/opatchauto apply /home/grid/28828733
...
==Following patches FAILED in analysis for apply:

Reason: Failed during Analysis: CheckSystemCommandsAvailable Failed, [ Prerequisite Status: FAILED, Prerequisite output:

After fixing the cause of failure Run opatchauto resume

看起來是缺失fuser命令，使用yum安裝便可，須要注意fuser對應的是psmisc：

yum install psmisc

再次嘗試應用補丁成功：

[root@db90 grid]# /u01/app/12.2.0/grid/OPatch/opatchauto apply /home/grid/28828733

在成功應用補丁以後，crsctl stat res -t -init查看acfs資源已恢復正常ONLINE：

--------------------------------------------------------------------------------

此時再次lsmod|grep oracle查詢，已經能夠看到oracleacfs部分：

$ lsmod|grep oracle
oracleacfs           4786907  0 
oracleadvm            781814  0 
oracleoks             634589  2 oracleacfs,oracleadvm

asmca也已經正常顯示出acfs相關內容。
