gfs2命令行配置手册l 创建集群：1、 首先通过ccs_tool工具创建集群：ccs_tool create nameofcluster2、 通过ccs_tool工具创建fence设备：ccs_tool addfence nameoffence agenttypeoffence -c3、 检查已经添加的fence设备：ccs_tool lsfencename agentfence-shared fence_manual4、 通过ccs_tool工具创建集群中的节点：ccs_tool addnode nameofnode v 1 n 1 f nameoffence -c5、 检查已经添加的节点：ccs_tool lsnodecluster name: 001, config_version: 6nodename votes nodeid f 1 1 1 2 1 3 1 4 fence-shared6、 在各个节点上同时启动集群服务：/etc/init.d/cman startstarting cluster: loading modules. done mounting configfs. done starting ccsd. done starting cman. done starting daemons. done starting fencing. done ok 7、 检查集群健康状态：clustat i 3cluster status for 001 thu nov 19 13:26:55 2009member status: quorate member name id status - - - - 1 online, local 2 online 3 online 4 online8、 更新集群配置：ccs_tool update /etc/cluster/cluster.confconfig file updated from version 6 to 7update complete.9、 删除集群节点：ccs_tool delnode nameofnode10、 删除集群fence设备：ccs_tool delfence nameoffencel 建立gfs（首先要连接iscsi设备，本文中由于iscsi使用的是专业存储，这里不介绍如何配置iscsi服务端了）1、 安装iscsi客户端：yum install iscsi-initiator-utils2、 发现网络上的iscsi设备：（如果以前挂载过别的iscsi设备，可以先将/var/lib/iscsi/nodes目录清空）/etc/init.d/iscsi restartiscsiadm -m discovery -t sendtargets -p 33:3260,1 .example:storage.disk2.sys1.xyz3:3260,1 .example:storage.disk2.sys1.xyz3:3260,1 .example:storage.disk2.sys1.xyz/etc/init.d/iscsi restartfdisk ldisk /dev/cciss/c0d0: 293.5 gb, 293563949056 bytes255 heads, 63 sectors/track, 35690 cylindersunits = cylinders of 16065 * 512 = 8225280 bytesdevice boot start end blocks id system/dev/cciss/c0d0p1 * 1 22419 180080586 83 linux/dev/cciss/c0d0p2 22420 35167 102398310 83 linux/dev/cciss/c0d0p3 35168 35689 4192965 82 linux swap / solarisdisk /dev/sda: 104.8 gb, 104855869440 bytes255 heads, 63 sectors/track, 12748 cylindersunits = cylinders of 16065 * 512 = 8225280 bytesdisk /dev/sda doesnt contain a valid partition table3、 在各个节点上都发现这个iscsi块设备。同上。4、 启动lvm和clvmlvmconf enable-cluster/etc/init.d/clvmd startstarting clvmd: ok activating vgs: ok -可以看到分区了。5、 创建物理卷pvcreate /dev/sda physical volume /dev/sda successfully created6、 创建卷组vgcreate “vg001” /dev/sda clustered volume group vg001 successfully created7、 创建逻辑卷lvcreate n lv001 l 50g vg001 logical volume lv001 created8、 格式化mkfs.gfs2 p lock_dlm j 4 t 001:lv001 /dev/vg001/lv001this will destroy any data on /dev/vg001/lv001.are you sure you want to proceed? y/n ydevice: /dev/vg001/lv001blocksize: 4096device size 50.00 gb (13107200 blocks)filesystem size: 50.00 gb (13107198 blocks)journals: 4resource groups: 200locking protocol: lock_dlmlock table: 001:lv001uuid: 5bf11f9e-ca03-266a-3f93-08bca289821f9、 挂载：mount t gfs2 o noatime,no
