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

环境：RHEL 7.3 + Oracle 12.2.0.1 RAC

现象：acfs资源状态不正常，asmca图形也没有acfs相关内容，无法使用acfs。

• 1.具体现象
• 2.定位bug
• 3.解决问题

1.具体现象

使用crsctl stat res -t -init查询，ora.drivers.acfs是OFFLINE状态：

$ crsctl stat res -t -init
--------------------------------------------------------------------------------
Name           Target  State        Server                   State details
--------------------------------------------------------------------------------
Cluster Resources
--------------------------------------------------------------------------------
ora.drivers.acfs
      1        ONLINE  OFFLINE                               STABLE
--------------------------------------------------------------------------------

使用lsmod|grep oracle查询，没有acfs内容：

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

尝试重装acfs，也会在卸载时就报错不支持：

# /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'

2.定位bug

确认OS内核版本：

[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)

结合MOS最终匹配定位是Bug 25078431导致。

3.解决问题

我这里选择应用最新的PSU（其中ACFS补丁集包含了25078431这个补丁），开始应用补丁时遇到一个问题如下：

[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

看起来是缺失fuser命令，使用yum安装即可，需要注意fuser对应的是psmisc：

yum install psmisc

再次尝试应用补丁成功：

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

在成功应用补丁之后，crsctl stat res -t -init查看acfs资源已恢复正常ONLINE：

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

此时再次lsmod|grep oracle查询，已经可以看到oracleacfs部分：

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

asmca也已经正常显示出acfs相关内容。
