REDHAT的GFS文件系统配置文档

一：软件包安装

gfs需要redhat cluster suite软件来协调gds node对共享存储的I/O操作，因此需要rhcs套件

cman

cman-devel

ipvsadm

perl-Net-Telnet

piranha

rgmanager

system-config-cluster

gfs套件

gfs2-utils

gfs-utils

kmod-gfs

kmod-gfs-xen

lvm2-cluster

此外cman需要openais支持

openais

openais-devel

[[email protected] ~]# yum install cman cman-devel ipvsadm perl-Net-Telnet piranha rgmanager system-config-cluster gfs2-utils gfs-utils kmod-gfs kmod-gfs-xen lvm2-cluster openais openais-devel rgmanager

二：配置hosts文件

[[email protected] ~]# vim /etc/hosts

172.31.2.180 GFS1

172.31.2.182 GFS2

[[email protected] ~]# vim /etc/hosts

172.31.2.180 GFS1

172.31.2.182 GFS2

三：修改locking_type的值

修改/etc/lvm/lvm.conf中的locking type值为3

[[email protected] ~]# vim /etc/lvm/lvm.conf

locking_type=3

[[email protected] ~]# vim /etc/lvm/lvm.conf

locking_type=3

四：配置system-config-cluster

配置Cluster nodes

add a cluster node

配置fencd device

选择manage fencing for this node

同上，add a new fence level

配置failover domains

五：启动服务进程

分别在两台启动进程

service cman start

service clvmd start

service gfs start

service rgmanager start

六：配置resource

[[email protected] ~]# pvcreate /dev/sdb

Physical volume "/dev/sdb" successfully created

[[email protected] ~]# pvscan

PV /dev/sdb lvm2 [30.00 GB]

Total: 1 [30.00 GB] / in use: 0 [0 ] / in no VG: 1 [30.00 GB]

[[email protected] ~]# vgcreate vggfs /dev/sdb

Clustered volume group "vggfs" successfully created

[[email protected] ~]# vgscan

Reading all physical volumes. This may take a while...

Found volume group "vggfs" using metadata type lvm2

[[email protected] ~]# vgdisplay

--- Volume group ---

VG Name vggfs

System ID

Format lvm2

Metadata Areas 1

Metadata Sequence No 1

VG Access read/write

VG Status resizable

Clustered yes

Shared no

MAX LV 0

Cur LV 0

Open LV 0

Max PV 0

Cur PV 1

Act PV 1

VG Size 30.00 GB

PE Size 4.00 MB

Total PE 7679

Alloc PE / Size 0 / 0

Free PE / Size 7679 / 30.00 GB

VG UUID RKsKuL-zvat-1wda-yzx0-5meI-RckL-w5HkzC

[[email protected] ~]# lvcreate -n data -l 7679 vggfs

Logical volume "data" created

[[email protected] ~]# mkfs.gfs -j 2 -p lock_dlm -t gfs_clusterr:vggfs /dev/vggfs/data

（选择lock_dlm模式，-j代表节点的个数）

七：挂载GFS文件系统

mount -t gfs /dev/vggfs/data /data

八：启动和关闭

chkconfig cman on

chkconfig clvmd on

chkconfig gfs on

chkconfig rgmanager on

设置分区启动表

vim /etc/fstab

/dev/vggfs/data /data gfs _netdev 0 0
