APP
配置集群文件系統(tǒng)：
?
安裝軟件包： yum -y install ??lvm2* gfs2* dlm*
?
1.安裝rpm包
?yum -y install ??lvm2* gfs2* dlm* fence-agents*
?
?
?
?
?
2.修改LVM配置文件改為集群模式-----暫時(shí)不做
/etc/lvm/lvm.conf
?
?locking_type = 1 改為 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
?
?

重啟主機(jī)生效
?
------------ ?創(chuàng)建cluster CLVM必須得創(chuàng)建fence機(jī)制
?
?
禁止集群投票，防止腦裂（由于我們集群是2個(gè)節(jié)點(diǎn)）
pcs ??property ??set no-quorum-policy=freeze
?
在生產(chǎn)環(huán)境中，可以用
[root@qhdb1 ~]# pcs ???stonith list

在我的生產(chǎn)環(huán)境中、我則會(huì)優(yōu)先選擇使用fence_mpath作為stonith資源限制
配置：我的存儲(chǔ)使用的日立的盤(pán)
?
?
修改/etc/multipath.conf 配置文件
?
defaults {
????????user_friendly_names yes
????????find_multipaths yes
????????reservation_key ???????0x2????依次命名節(jié)點(diǎn)1 2 3
}
?
?
?
?
?
?
2節(jié)點(diǎn)：
?
?
?
?
?
?
?
重啟multipath
systemctl restart multipathd
multipath
?
?
配置stonith設(shè)備：
?
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，防止腦裂（由于我們集群是2個(gè)節(jié)點(diǎn)）
pcs ??property ??set no-quorum-policy=freeze
?
?
?
添加dlm資源
pcs resource create dlm ocf:pacemaker:controld op monitor interval=30s on-fail=fence clone interleave=true ordered=true
?
啟用集群鎖模式的clvm
lvmconf ?--enable-cluster ???---
?
添加clvm資源
pcs resource create clvmd ocf:heartbeat:clvm op monitor interval=30s on-fail=fence clone interleave=true ordered=true
?
?
?
?
?
創(chuàng)建dlm資源和clvm資源的依賴(lài)關(guān)系和啟動(dòng)順序：
?
pcs constraint order start dlm-clone then clvmd-clone
pcs constraint colocation add clvmd-clone with dlm-clone
?
?
創(chuàng)建文件系統(tǒng)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資源：
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
?
創(chuàng)建 gfs2和clvmd的啟動(dòng)順序和依賴(lài)關(guān)系：
pcs ?constraint order ?start ?clvmd-clone then ?pg01_file1-clone
pcs ?constraint colocation add pg01_file1-clone with clvmd-clone
