/vmware/share/oraw.vmdk"
|用于Oracle集群注册表文件和CRS表决磁盘
2个虚拟机使用一个共享磁盘
四、安装虚拟机
1.在vmwareconsole创建vmwareguestOS,取名gfs-node01,选择customecreate->
RedhatEnterpriseLinux464-bit，其它都是默认.
内存选择1G（>
800MB你就看不到warning了）,硬盘大小选择12GB,建立方式不选择pre-allocated
2.创建好后vmwareguestOS之后,给guest加上一块NIC（也就是网卡）
3.关掉vmwareconsole，在node1目录下面，打开gfs-node1.vmx,在最后空白处添加以下内容
scsi1.present="
TRUE"
scsi1.virtualDev="
lsilogic"
scsi1.sharedBus="
virtual"
scsi1:
1.present="
1.mode="
independent-persistent"
1.filename="
1.deviceType="

2.present="
2.mode="
2.filename="

disk.locking="

diskLib.dataCacheMaxSize="
0"
diskLib.dataCacheMaxReadAheadSize="
diskLib.DataCacheMinReadAheadSize="
diskLib.dataCachePageSize="
4096"
diskLib.maxUnsyncedWrites="
这段是对vmware使用共享硬盘的方式进行定义，大多数人都知道设置disk.locking="
却漏掉dataCache
保存退出之后，重新打开你的vmware-console,你就可以看到vmwareguestOS的配置中，都有这些硬盘出现了.
五、需要安装的包以及顺序
可以用yum安装:
1、升级CentOS4.4
yumupdate
2、安装csgfs
yuminstallyumex
cd/etc/yum.repos.d
wgethttp:
//mirror.centos.org/centos/4/csgfs/CentOS-csgfs.repo
yumex
也可以手动rpm安装:
包下载地址：
http:
//mirror.centos.org/centos/4/csgfs/x86_64/RPMS/
1、在所有节点上安装必须的软件包，软件包完整列表请参考GFS6.1用户手册

2、安装软件和顺序
安装脚本，install.sh
#!
/bin/bash

rpm-ivhkernel-smp-devel-2.6.9-42.EL.x86_64.rpm

rpm-ivhmagma-plugins-1.0.9-0.x86_64.rpm

rpm-ivhipvsadm-1.24-6.x86_64.rpm
rpmivhpiranha-0.8.2-1.x86_64.rpm--nodeps
注意：
有些包有依赖关系，使用nodeps开关进行安装即可
3、修改各个节点上的/etc/hosts文件（每个节点都一样）
如下：
[root@gfs-node1etc]#cathosts
#Donotremovethefollowingline,orvariousprograms
#thatrequirenetworkfunctionalitywillfail.
127.0.0.1
localhost.localdomainlocalhost
192.168.154.211gfs-node1
192.168.154.212gfs-node2
192.168.10.1
node1-prv
192.168.10.2
node2-prv
192.168.154.201node1-vip
192.168.154.202node2-vip
主机名、cluster主机名、ocs中的pub节点名最好相同。
六、运行system-config-cluster进行配置
增加2个节点，节点的权置全部设置为1，即Quorum值设置为1
三个节点的名称为:
gfs-node1
gfs-node2
修改cluster.conf文件，如下：
[root@gfs-node1~]#cat/etc/cluster/cluster.conf
<
?
xmlversion="
1.0"
>
clusterconfig_version="
1"
name="
alpha_cluster"
fence_daemonpost_fail_delay="
post_join_delay="
3"
/>
clusternodes>
<
clusternodename="
gfs-node1"
votes="

methodname="
devicename="
F-Man"
nodename="
ipaddr="
192.168.10.1"
/method>
/fence>
/clusternode>
gfs-node2"
192.168.10.2"
/clusternodes>
cman/>

/fencedevices>

failoverdomainname="

failoverdomainnodename="
gfs-node01"
priority="
gfs-node02"
2"
gfs-node03"
/failoverdomain>
/failoverdomains>
/rm>
/cluster>
[注意]Usefence_bladecenter.
Thiswillrequirethatyouhavetelnetenabledon
yourmanagementmodule（mayrequireafirmwareupdate）
使用scp命令把这个配置文件copy到node2节点上
七、在01/02节点上启动dlm,ccsd,fence等服务
可能在安装配置完上述步骤后，下面这些服务已经起来了。
在2个节点上加载dlm模块
[root@gfs-node1cluster]#modprobelock_dlm
[root@gfs-node2cluster]#modprobelock_dlm
5.2、启动ccsd服务
[root@gfs-node1cluster]#ccsd
[root@gfs-node2cluster]#ccsd
5.3、启动集群管理器（cman）
root@gfs-node1#/sbin/cman_tooljoin
root@gfs-node2#/sbin/cman_tooljoin
5.4、测试ccsd服务
（注意：
ccsd的测试要等cman启动完成后，然后才可以进行下面的测试
[root@gfs-node1cluster]#ccs_testconnect
[root@gfs-node2cluster]#ccs_testconnect
#ccs_testconnect各个节点的返回如下：
node1：
Connectsuccessful.
Connectiondescriptor=0
node2：
Connectiondescriptor=30
5.5、查看节点状态
cat/proc/cluster/nodes,应该返回
[root@gfs-node1cluster]#cat/proc/cluster/nodes
