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

 

[root@GFS1 ~]# 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

[root@GFS2 ~]# 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

[root@GFS1 ~]# vim /etc/hosts

172.31.2.180     GFS1

172.31.2.182     GFS2

[root@GFS2 ~]# 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

[root@GFS1 ~]# vim /etc/lvm/lvm.conf

locking_type=3

[root@GFS2 ~]# vim /etc/lvm/lvm.conf

locking_type=3

 

四：配置system-config-cluster

 

配置Cluster nodes

 

add a cluster node

 

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

[root@GFS1 ~]# pvcreate /dev/sdb

 Physical volume "/dev/sdb" successfully created

[root@GFS1 ~]# pvscan

 PV /dev/sdb                       lvm2 [30.00 GB]

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

[root@GFS1 ~]# vgcreate vggfs /dev/sdb

 Clustered volume group "vggfs" successfully created

[root@GFS1 ~]# vgscan

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

 Found volume group "vggfs" using metadata type lvm2

[root@GFS1 ~]# 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

  

[root@GFS1 ~]# lvcreate -n data -l 7679 vggfs

 Logical volume "data" created

 

[root@GFS1 ~]# 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
