GFS7配置手册

1) 在所有节点上建立dist vol目录
[root@node1 ~]# mkdir -p /gfs/dist

2) 加入node2,node3节点至GFS Cluster
[root@node1 ~]# gluster peer probe node2
peer probe: success. 
[root@node1 ~]# gluster peer probe node3

3) 创建Dist Vol
[root@node1 ~]# gluster volume create dist_vol transport tcp node1:/gfs/dist node2:/gfs/dist node3:/gfs/dist force
volume create: dist_vol: success: please start the volume to access data

[root@node1 ~]# gluster volume start dist_vol
volume start: dist_vol: success

[root@node1 ~]# gluster volume info
Volume Name: dist_vol
Type: Distribute
Volume ID: 89287b49-1c7c-4331-bbe0-f5182d807085
Status: Started
Snapshot Count: 0

1) 安装GFS源及相关软件
[root@node7 ~]# yum install centos-release-gluster7 -y
[root@node7 ~]# sed -i -e "s/enabled=1/enabled=0/g" /etc/yum.repos.d/CentOS-Gluster-7.repo
[root@node7 ~]# yum --enablerepo=centos-gluster7 install glusterfs glusterfs-fuse -y

2) 挂载
[root@node7 ~]# mount -t glusterfs node1.1000cc.net:/dist_vol /mnt
[root@node7 ~]# df -Th | grep /mnt
node1.1000cc.net:/dist_vol fuse.glusterfs   50G  5.1G   43G  11% /mnt

1) 启用quota机制
[root@node1 ~]# gluster volume quota dist_vol enable
volume quota : success

[root@node1 ~]# gluster volume info
Volume Name: dist_vol
Type: Distribute
Volume ID: 6273b119-07ab-4e82-ab1a-2043410a93ec
Status: Started
Snapshot Count: 0
Number of Bricks: 3
Transport-type: tcp
Bricks:
Brick1: srv1:/gfs/dist
Brick2: srv2:/gfs/dist

Options Reconfigured:
features.quota-deem-statfs: on
features.inode-quota: on
features.quota: on
storage.fips-mode-rchecksum: on
transport.address-family: inet
nfs.disable: on

2) 关闭quota机制
[root@node1 ~]# gluster volume quota dist_vol disable
Disabling quota will delete all the quota configuration. Do you want to continue? (y/n) y
volume quota : success

3) 为指定卷设置限额
(1) 开启限额
[root@node1 ~]# gluster volume quota dist_vol limit-usage / 1GB 
volume quota : success

(2) 客户端测试
[root@node5 ~]# mkdir /mnt/gfs

[root@node5 ~]# mount.glusterfs srv1.1000y.cloud:/dist_vol /mnt/gfs

[root@node5 ~]# df -Th | grep /mnt/gfs
srv1.1000y.cloud:/dist_vol fuse.glusterfs  1.0G     0  1.0G   0% /mnt/gfs

(3) 如不需要在客户端上显示配额大小，而打算显示整个磁盘大小可按以下操作
[root@node1 ~]# gluster volume set dist_vol quota-deem-statfs off
volume set: success

4) 为指定卷的目录设置限额
(1) 客户端创建gfs卷的一个目录
[root@node5 ~]# mkdir /mnt/gfs/qyy

(2) 为gfs卷的指定目录设定权限并确认
[root@node1 ~]# gluster volume quota dist_vol limit-usage /qyy 1GB
volume quota : success

[root@node1 ~]# gluster volume quota dist_vol list
		Path   Hard-limit  Soft-limit      Used  Available  Soft-limit exceeded? Hard-limit exceeded?
-----------------------------------------------------------------------------------------------------
/qyy            1.0GB     80%(819.2MB)   0Bytes   1.0GB              No                   No

(3) 客户端验证
[root@node5 ~]# df -Th /mnt/gfs/qyy
Filesystem                 Type            Size  Used Avail Use% Mounted on
srv1.1000y.cloud:/dist_vol fuse.glusterfs  1.0G     0  1.0G   0% /mnt/gfs

5) 更改quota的软限额---设定软限额为70%
[root@node1 ~]# gluster volume quota dist_vol limit-usage /qyy 1GB 70
volume quota : success

[root@node1 ~]# gluster volume quota dist_vol list
		Path   Hard-limit  Soft-limit      Used  Available  Soft-limit exceeded? Hard-limit exceeded?
-----------------------------------------------------------------------------------------------------
/qyy            1.0GB     70%(716.8MB)   0Bytes   1.0GB              No                   No

6) 删除限额
(1) 删除指定gfs卷的目录限额
[root@node1 ~]# gluster volume quota dist_vol remove /qyy
volume quota : success

(2) 删除指定gfs卷的/限额
[root@node1 ~]# gluster volume quota dist_vol remove /
volume quota : success

(3) 验证
[root@node1 ~]# gluster volume quota dist_vol list
quota: No quota configured on volume dist_vol

1) 请先完成Distributed配置

2) 关闭Gluster的NFS支持(默认Distributed模式，已经关闭
[root@node1 ~]# gluster volume set dist_vol nfs.disable on
volume set: success

[root@node1 ~]# gluster volume get dist_vol nfs.disable
Option                                  Value
------                                  ----- 
nfs.disable                             on

# 如果NFS服务开启，请关闭(所有节点)
[root@node1 ~]# systemctl disable --now nfs-server

3) 在Gluster的某一个集群节点上安装及配置NFS-Ganesha
[root@node1 ~]# yum install centos-release-nfs-ganesha30 -y

[root@node1 ~]# sed -i -e "s/enabled=1/enabled=0/g" /etc/yum.repos.d/CentOS-NFS-Ganesha-30.repo

    # 设定NFSv4的Pseudo path
    Pseudo="/vfs_dist";
    SecType = "sys";
}
LOG {
    # Log级别
    Default_Log_Level = WARN;
}

[root@node1 ~]# systemctl enable --now nfs-ganesha

4) 设置SELinux
[root@node1 ~]# vim nfs-ganesha.te
module nfs-ganesha 1.0;

require {
        type var_lib_nfs_t;
        type init_t;
        class dir create;
}

#============= init_t ==============
allow init_t var_lib_nfs_t:dir create;

[root@node1 ~]# checkmodule -m -M -o nfs-ganesha.mod nfs-ganesha.te
checkmodule: loading policy configuration from nfs-ganesha.te
checkmodule: policy configuration loaded

checkmodule: writing binary representation (version 19) to nfs-ganesha.mod
[root@node1 ~]# semodule_package --outfile nfs-ganesha.pp --module nfs-ganesha.mod
[root@node1 ~]# semodule -i nfs-ganesha.pp

5) 设置防火墙
[root@node1 ~]# firewall-cmd --add-service=nfs --permanent

2) 从卷中移除节点,并等待重新平衡结束
[root@node1 ~]# gluster volume remove-brick dist_vol node4:/gfs/dist start
Running remove-brick with cluster.force-migration enabled can result in data corruption. It is safer to disable this option so that files that receive writes during migration are not migrated.
Files that are not migrated can then be manually copied after the remove-brick commit operation.
Do you want to continue with your current cluster.force-migration settings? (y/n) y
volume remove-brick start: success
ID: f2e9e0c3-469a-4f3d-834c-37467f25e873

3) 验证状态

 -----------         --------------------------
completed                  0:00:01

4) 确认状态为completed后，移除节点
[root@node1 ~]# gluster volume remove-brick  dist_vol node4:/gfs/dist commit
volume remove-brick commit: success
Check the removed bricks to ensure all files are migrated.
If files with data are found on the brick path, copy them via a gluster mount point before re-purposing the removed brick.
