1. GFS 구성을 위해 패키지 설치

yum groupinstall "Cluster Storage"

yum groupinstall "Clustering"

 

2. Cluster 설정 파일 생성

다음과 같이 생성 후 다른 노드에 복사

# cat /etc/cluster/cluster.conf
<?xml version="1.0"?>
<cluster config_version="14" name="rac_tac">
        <clusternodes>
                <clusternode name="rac01" nodeid="1"/>
                <clusternode name="rac02" nodeid="2"/>
        </clusternodes>
        <cman expected_votes="1" transport="udpu" two_node="1"/>
        <rm>
                <resources>
                        <clusterfs device="/dev/mapper/datavg-datalv" force_unmount="1" fsid="32134" fstype="gfs2" mountpoint="/rac_data" name="tibdata" self_fence="1"/>
                        <lvm lv_name="raw1" name="rawdev1" vg_name="oravg"/>
                        <lvm lv_name="raw2" name="rawdev2" vg_name="oravg"/>
                        <lvm lv_name="raw3" name="rawdev3" vg_name="oravg"/>
                        <lvm lv_name="raw4" name="rawdev4" vg_name="oravg"/>
                </resources>
        </rm>
</cluster>

 

3. gfs2 파일 시스템 생성

- lvm 생성

pvcreate /dev/sda

vgcreate volGFS /dev/sda

lvcreate -L 8G volGFS

pvscan

vgscan

 

- 파티션 포맷

mkfs.gfs2 -p lock_dlm -t cluster112:gfs1 -j 3 /dev/volGFS/lvol0

 

- gfs 파티션 마운트

mount -t gfs2 -o upgrade /dev/volGFS/lvol0 /mnt/gfs

 

- /etc/fstab에 마운트 정보 입력

/dev/volGFS/lovl0  /mnt/gfs  gfs2  defaults 0 0

 

4. 서비스 시작

양 노드에서 수행

service cman start

service clvmd start

service gfs2 restart

 

chkconfig cman on

chkconfg clvmd on

chkconfg gfs2 on

chkconfg acpid off

 

5. 서비스 확인
