Linux基于大于2TB磁盘挂载
首先查看服务器磁盘，这里将LINUX系统安装在sda，应用程序用于存放在sdb
[root@voices-bak ~]# fdisk -l
Disk /dev/sda: 127.0 GB, 126999330816 bytes, 248045568 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk label type: dos
Disk identifier: 0x000da1b5

Disk /dev/sdb: 23998.0 GB, 23997999742976 bytes, 46871093248 sectors

I/O size (minimum/optimal): 512 bytes / 512 bytes
这里选择/dev/sdb
[root@voices-bak ~]# parted /dev/sdb

格式化磁盘
[root@voices-bak ~]# mkfs.xfs -f /dev/sdb
创建LVM卷
# pvcreate
[root@voices-bak ~]# pvcreate /dev/sdb
