在k8s-node1，k8s-node2，k8s-node3上配置磁盘，本人使用的是virtualbox虚拟机，额外挂在一块磁盘

lsblk

mkfs.xfs -f /dev/sdb

mkdir /glusterfs
mount /dev/sdb /glusterfs
mkdir -p /glusterfs/replica

记录sdb的UUID

lsblk -o NAME,UUID,MOUNTPOINT,FSTYPE

vi /etc/fstab

追加

在k8s-node1，k8s-node2，k8s-node3上安装glusterfs-server

sudo apt -y install glusterfs-server

sudo systemctl enable --now glusterd

gluster --version

在k8s-node1上，追加peer

gluster peer probe k8s-node2
gluster peer probe k8s-node3

gluster peer status

在k8s-node1上，创建volume replica

gluster volume create vol_replica replica 3 transport tcp \
k8s-node1:/glusterfs/replica \
k8s-node2:/glusterfs/replica \
k8s-node3:/glusterfs/replica

gluster volume start vol_replica

gluster volume info

在k8s-master上，安装glusterfs-client测试

sudo apt -y install glusterfs-client

mkdir -p /mnt/vol_replica
mount -t glusterfs k8s-node1:/vol_replica /mnt/vol_replica

df -hT

完结！
