#cinder块存储
#需要准备存储节点,可以使用LVM、NFS、分布式存储等
#本次安装以LVM、NFS为例

#基本配置
# hostname cinder1
# IP 192.168.58.24
# hostnamectl set-hostname cinder1
#hosts设置

##############
#添加硬盘……
#fdisk快速分区,新建2个30G分区
echo -e 'n\np\n1\n\n+30G\nw' | fdisk /dev/sdb
echo -e 'n\np\n2\n\n+30G\nw' | fdisk /dev/sdb
#格式化
mkfs.ext4 /dev/sdb1
mkfs.ext4 /dev/sdb2

mkdir -p /data
mount -t ext4 /dev/sdb1 /data
df -h|grep /dev/sdb1
#开机挂载磁盘
echo "mount -t ext4 /dev/sdb1 /data" >>/etc/rc.d/rc.local
tail -1 /etc/rc.d/rc.local
chmod +x /etc/rc.d/rc.local

##############
#安装配置LVM，作为后端存储使用
yum install -y lvm2
systemctl enable lvm2-lvmetad.service
systemctl start lvm2-lvmetad.service
#创建LVM物理卷pv与卷组vg
pvcreate /dev/sdb2
vgcreate cinder_lvm01 /dev/sdb2
vgdisplay #查看vg

##############
#安装配置NFS服务，作为后端存储使用
yum install nfs-utils rpcbind -y
mkdir -p /data/{cinder_nfs1,cinder_nfs2}
chown cinder:cinder /data/cinder_nfs1
chmod 777 /data/cinder_nfs1
#echo "/data/cinder_nfs1 *(rw,no_root_squash,sync)">/etc/exports
