安装:

yum install -y glusterfs{,-server,-fuse,-geo-replication}

如不使用主从复制,可以不装glusterfs-geo-replication


操作:

 gluster peer command

gluster peer status

gluster peer probe server //添加机器

gluster peer detach server //踢出机器

gluster volume create NEW-VOLNAME [stripe COUNT | replica COUNT] [transport [tcp | rdma | tcp,rdma]]  NEW-BRICK1 NEW-BRICK2 NEW-BRICK3 //创建volume

gluster volume create vol1 replica 2 transport tcp gluster-node01:/gluster/brick1 gluster-node02:/gluster/brick1

gluster volume start VOLNAME //启用某一volume

gluster volume delete VOLNAME //删除volume

 

mount -t glusterfs HOSTNAME-OR-IPADDRESS:/VOLNAME MOUNTDIR //挂载volume

 mount -t glusterfs -o backupvolfile-server=volfile_server2,fetch- attempts=2,log-level=WARNING,log-file=/var/log/gluster.log server1:/test-volume /mnt/glusterfs

gluster volume rebalance VOLNAME start   //均衡负载

gluster volume rebalance VOLNAME start force //强制均衡

gluster volume rebalance VOLNAME status //查看均衡状态

gluster volume rebalance VOLNAME stop //停止均衡

gluster volume heal VOLNAME //修复损坏的文件

gluster volume heal VOLNAME full //修复所有的文件(检查健康文件是否损坏,如果损坏进行修复)

gluster volume heal VOLNAME info //查看需要修复的文件信息

gluster volume heal VOLNAME info healed //查看修复的文件信息

gluster volume heal VOLNAME info failed //查看没有修复的文件信息

gluster volume heal VOLNAME info split-brain //查看脑裂文件信息(如果有脑裂文件,直接把坏的脑裂文件删除进行文件修复即可,据说3.3以后的版本有个赢链接,在修复时仍然会把脑裂文件恢复,可以把链接文件找到一并删除或是直接把目录下所有文件删除)

查找硬链接流程:

cd到brick所在目录下面进入.glusterfs目录下对应的hash目录中找到硬链接文件

磁盘操作:

 gluster peer probe HOSTNAME //添加主机

gluster volume add-brick VOLNAME NEW-BRICK //添加brack

gluster volume info //查看状态

gluster volume remove-brick VOLNAME BRICK start //删除brick

gluster volume remove-brick VOLNAME BRICK status //删除状态

gluster volume remove-brick VOLNAME BRICK commit //直接提交删除(不用输入yes)

gluster volume replace-brick VOLNAME BRICKOLD-BRICK BRICKNEW-BRICK start //迁移brick数据

gluster volume replace-brick VOLNAME BRICK NEW-BRICK  pause //停止迁移

gluster volume replace-brick VOLNAME BRICK NEW-BRICK abort //中断迁移

gluster volume replace-brick VOLNAME BRICK NEW-BRICK status //迁移状态

gluster volume replace-brick VOLNAME BRICK NEW-BRICK commit //直接提交迁移

 gluster volume info VOLNAME //整体状态查看

磁盘或者数据迁移操作后进行负载操作(系统默认启动了负载程序,可以不做操作,如果设置中停了此程序或者想立马见到效果可以做如下操作):

gluster volume rebalance VOLNAME fix-layout start //开始负载均衡

gluster volume rebalance VOLNAME start

 gluster volume rebalance VOLNAME start force

gluster volume rebalance VOLNAME status

gluster volume rebalance VOLNAME stop
