glusterfs相关笔记

在centos设置可能是最容易的分布式文件系统， 毕竟是redhat的东西

gluster-arch

compared to ceph

“Ceph is part and parcel to the OpenStack story. In the community, [the majority] of the OpenStack implementations were using Ceph as the storage substrate. Gluster is classic file serving, second-tier storage, and deep archiving.”

安装

先设置三台服务器

yum install wget
yum install centos-release-gluster -y
yum install epel-release -y
yum install glusterfs-server -y

启动服务

systemctl start glusterd
systemctl enable glusterd

寻找peers

找到另两台服务器

gluster peer probe server2
gluster peer probe server3

建立bricks

在三台服务器上分别建三个目录, 注意/data是glusterfs最终会放置数据的分区， 保留空间

mkdir -p /data/glusters/myvol1/brick1/brick

建一个分布式volume

我们使用stripe， 具体含义和raid中一样

gluster volume create myvol1 stripe 3 server1:/data/glusters/myvol1/brick1/brick server2:/data/glusters/myvol1/brick1/brick server3:/data/glusters/myvol1/brick1/brick
gluster volume start myvol1
gluster volume info myvol1
gluster volume set shadowvol nfs.disable off # 启用nfs挂载

挂载volume

# 注意在server1上挂载server1
mount -t nfs -o vers=3 server1:/myvol1 /mnt/glusters

查看空间

df /mnt/glusters
