脚本宝典收集整理的这篇文章主要介绍了Linux7安装pacemaker+corosync集群-02--配置集群文件系统gfs2(dlm+clvmd)，脚本宝典觉得挺不错的，现在分享给大家，也给大家做个参考。

配置集群文件系统：

 

安装软件包： yum -y install   LVM2* gfs2* dlm*

 

1.安装rpm包

 yum -y install   lvm2* gfs2* dlm* fence-agents*

 

 

 

 

 

2.修改LVM配置文件改为集群模式-----暂时不做

/etc/lvm/lvm.conf

 

 locking_tyPE = 1 改为 locking_type = 3

 

 

 

 

 

[root@qhdb2 lvm]# lvmconf -h

usage: /usr/sbin/lvmconf <command>

 

Commands:

Enable clvm:  --enable-cluster [--lockinglibdir <dir>] [--lockinglib <lib>]

Disable clvm: --disable-cluster

Enable halvm: --enable-halvm

Disable halvm: --disable-halvm

Set locking library: --lockinglibdir <dir> [--lockinglib <lib>]

 

Global options:

config file location: --file <configfile>

Set services: --services [--mirrorservice] [--startstopservices]

 

Use the separate command 'lvmconfig' to display configuration information

 

 

 

 

重启主机生效

 

------------  创建cluster CLVM必须得创建fence机制

 

 

禁止集群投票，防止脑裂（由于我们集群是2个节点）

pcs   PRoperty   set no-quorum-policy=freeze

 

在生产环境中，可以用

[root@qhdb1 ~]# pcs    stonITh list

在我的生产环境中、我则会优先选择使用fence_mpath作为stonith资源限制

配置：我的存储使用的日立的盘

 

 

修改/etc/multipath.conf 配置文件

 

defaults {

        user_friendly_@R_360_1507@ yes

        find_multipaths yes

        reservation_key        0x2    依次命名节点1 2 3

}

 

 

 

 

 

 

2节点：

 

 

 

 

 

 

 

重启multipath

systemctl restart multipathd

multipath

 

 

配置stonith设备：

 

pcs stonith create qhdb1_pcmk fence_mpath key=1 pcmk_host_list="qhdb1" pcmk_reboot_action="off"   devices="/dev/mapper/mpathe,/dev/mapper/mpathf" meta provides=unfencing

pcs stonith create qhdb2_pcmk fence_mpath key=2 pcmk_host_list="qhdb2" pcmk_reboot_action="off"   devices="/dev/mapper/mpathe,/dev/mapper/mpathf" meta provides=unfencing

或者

pcs  stonith create  pg_cluster_st  fence_mpath devices="/dev/mapper/mpathe,/dev/mapper/mpathf"   pcmk_host_map="qhdb1:1;qhdb2:2"  pcmk_monitor_action="metadata" pcmk_reboot_action="off" pcmk_host_argument="key" meta provides=unfencing

 

 

 

 

禁止集群投票，防止脑裂（由于我们集群是2个节点）

pcs   property   set no-quorum-policy=freeze

 

 

 

添加dlm资源

pcs resource create dlm oCF:pacemaker:controld op monitor interval=30s on-fail=fence clone interleave=true ordered=true

 

启用集群锁模式的clvm

lvmconf  --enable-cluster    ---

 

添加clvm资源

pcs resource create clvmd ocf:heartbeat:clvm op monitor interval=30s on-fail=fence clone interleave=true ordered=true

 

 

 

 

 

创建dlm资源和clvm资源的依赖关系和启动顺序：

 

pcs constraint order start dlm-clone then clvmd-clone

pcs constraint colocation add clvmd-clone with dlm-clone

 

 

创建文件系统gfs2

pvcreate  /dev/mapper/mpathe   /dev/mapper/mpathf  

vgcreate -Ay -cy  vg01 /dev/mapper/mpathe  /dev/mapper/mpathf

lvcreate  -L +200G -n lv_01   vg01

 

mkfs.gfs2  -p lock_dlm  -j 2 -t pg_cluster:file1  /dev/vg01/lv_01

 

 

 

 

 

添加clusterfs资源：

pcs  resource  create pg01_file1   ocf:heartbeat:Filesystem  device="/dev/vg01/lv_01" directory="/pg01" fstype="gfs2"   "options=noatime" op monitor interval=10s on-fail=fence clone interleave=true

或者？？？？

pcs  resource  create pg01_file1   Filesystem  device="/dev/vg01/lv_01" directory="/pg01" fstype="gfs2"   "options=noatime" op monitor interval=10s on-fail=fence clone interleave=true

 

创建 gfs2和clvmd的启动顺序和依赖关系：

pcs  constraint order  start  clvmd-clone then  pg01_file1-clone

pcs  constraint colocation add pg01_file1-clone with clvmd-clone
