1、关机更换硬盘
2、格式化硬盘
[root@BigDataHadoopDN2PRD data2]# parted -s /dev/sdc mklabel gpt
[root@BigDataHadoopDN2PRD data2]# parted -s /dev/sdc mkpart primary ext2 0 100%
Warning: The resulting partition is not properly aligned for best performance.
[root@BigDataHadoopDN2PRD data2]# mkfs.ext4 /dev/sdc1 --此处格式化时间较长，大约30-40分钟
mke2fs 1.41.12 (17-May-2010)
/dev/sdc1 alignment is offset by 3072 bytes.
This may result in very poor performance, (re)-partitioning suggested.

done
This filesystem will be automatically checked every 34 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.
3、挂载新硬盘
原文件 /etc/fstab中有/dev/sdc1的挂载，直接mount -a即可
或者mount /dev/sdc1 /data2
