（1）用parted命令给硬盘分区parted /dev/sdc（2）查看一下print Model: ATA WDC WD3000FYYZ-0 (scsi)Disk /dev/sdc: 3001GB
（1）用parted命令给硬盘分区
parted /dev/sdc（2）查看一下
print Model: ATA WDC WD3000FYYZ-0 (scsi)Disk /dev/sdc: 3001GBSector size (logical/physical): 512B/512BPartition Table: msdosNumber Start End Size Type File system Flags（3） 设置分区类型为gpt

(parted) quit 信息: You may need to update /etc/fstab. （7）格式化新硬盘
mkfs.ext4 /dev/sdc1（8）挂载硬盘到目录u02
mount /dev/sdc1 /u02（9）修改/etc/fstab，使开机也能挂载硬盘
vi /etc/fstab/dev/sdc1 /u02 ext4 defaults 1 2（10）重启设备，然后df -h查看挂载情况
