【存储】nas模拟裸磁盘挂载swift

1.利用nfs设置Linux系统之间的文件共享

2.安装yum install -y nfs-utils rpcbind

    2.1服务端客户端都进行安装

3.配置文件修改：/etc/exports

    3.1启动服务（顺序不能打乱） /bin/systemctl start rpcbind.service      /bin/systemctl start nfs.service

    3.2否则出现

4.showmount –e查看一下，看看共享的目录情况（记得创建相应的目录）

    4.1查看其他机器的共享情况

5.挂载

    mount -t nfs  172.16.254.132：/srv/node/vdd

6.构建ring（脚本）

#!/bin/bash

set -e

echo_green() {

echo -n -e "\033[32m$1\033[0m"

}

echo_green_enter() {

echo -e "\033[32m$1\033[0m"

}

##Usage

usage() {

        local command=`basename $0`

        echo "NAME

        ${command} -- Create initial rings

SYNOPSIS

        ${command} [IPS] [DEVICES]     

USAGE:

        $0 192.168.1.2 sdb1

        $0 192.168.1.2,192.168.1.3 sdb1,sdc1"

        exit 1

}

if [ $# -ne 2 ]

then

IPS=$1

IP=$(echo ${IPS}|sed 's/,/ /g')

DEVICES=$2

DEVICE=$(echo ${DEVICES}|sed 's/,/ /g')

#device_array=($DEVICE)

#device_1=${device_array[0]}

7.重启后swift后（异常）;

8总结：nas挂载的目录无法直接给与swift存储使用。
