Parted挂载2T以上硬盘，做LVM后安装NFS服务

1. 查看分区信息表，找到需要挂载的分区，由于本次挂载的分区大于2T，故选择parted命令执行；
fdisk -l
2. 使用gpt分区表对/dev/xvde进行分区
parted /dev/xvde mklabel gpt
3.对分区磁盘设置大小和分区类型
mkpart

将分区所有空间分区出来
(parted) mkpart primary 1 100%                                           
(parted) p
Model: Xen Virtual Block Device (xvd)
Disk /dev/xvdf: 7516GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt
Disk Flags: 
 
Number  Start   End     Size    File system  Name     标志
 1      1049kB  7516GB  7516GB               primary
标记为LVM
(parted) toggle 1 lvm 

4#创建PV
pvcreate /dev/xvde1
5#创建VG
vgcreate tomcat_data112 /dev/xvde1
6#创建LV
lvcreate -l 100%FREE -n data tomcat_data112
7#格式化文件格式ext4
mkfs.ext4 /dev/mapper/tomcat_data112-data

5.5 扩容VG，将/dev/xvde1加入到cetos组中
 
vgextend centos /dev/xvde1
 
6.5 扩容LV
 
EXT文件系统扩容LV
 
lvresize -L 2T /dev/mapper/centos-home
 
XFS扩容LV前先查看fstab文件中home文件类型
[root@mdosbackup ~]# cat /etc/fstab  |grep centos-home
/dev/mapper/centos-home /home                   xfs     defaults        0 0
 
[root@mdosbackup ~]# xfs_growfs  /dev/mapper/centos-home

8#创建挂载目录/data
mkdir /data
9#查看UUID
blkid
10#修改启动文件，将挂载磁盘写入fastab
vi /etc/fstab

11#挂载所有
mount -a

12#拷贝local.repo本地yum配置文件到本机
scp root@10.216.72.14:/etc/yum.repos.d/local.repo .
13#查看local.repo
[local]
name=CentOS 7
baseurl=http://10.216.72.13/CentOS7.8/CentOS7.8/
enabled=1
gpgcheck=0

14#清除yum源
yum clean all
15#建立yum缓存
yum makecache fast

16#安装nfs软件，服务端/客户端均需要安装
yum install -y nfs-utils
#开机启动rpcbind服务器
chkconfig rpcbind on
#启动nfs服务、
systemctl start nfs
#开机自启动nfs服务
systemctl enable nfs

17编辑服务端exports文件（NFS共享设置文件）
vi /etc/exports
   /data 10.216.98.113(rw,no_root_squash,no_all_squash,sync)
   service rpcbind start

18.重启rpcbind nfs 服务
systemctl restart rpcbind;systemctl restart nfs
19.停止firewalld服务
systemctl stop firewalld
