在linux系统中对大于2T的硬盘，使用fdisk进行分区，不是很好用，我们应该使用parted进行分区
一、查看系统中待分区的硬盘信息
[root@zabbix-c1 ~]# fdisk -l Disk /dev/sda: 214.7 GB, 214748364800 bytes 255 heads, 63 sectors/track, 26108 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00049d20 Device Boot Start End Blocks Id System /dev/sda1 * 1 26 204800 83 Linux Partition 1 does not end on cylinder boundary. /dev/sda2 26 281 2048000 82 Linux swap / Solaris Partition 2 does not end on cylinder boundary. /dev/sda3 281 26109 207461376 83 Linux Disk /dev/sdb: 21.5 GB, 21474836480 bytes 255 heads, 63 sectors/track, 2610 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xc1760957 Device Boot Start End Blocks Id System /dev/sdb1 1 26 208813+ 83 Linux Disk /dev/sdc: 3221.2 GB, 3221225472000 bytes 255 heads, 63 sectors/track, 391625 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Disk /dev/sdd: 5368.7 GB, 5368709120000 bytes 255 heads, 63 sectors/track, 652708 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000
二、在上面的结果中我们可以看到/dev/sdc和/dev/sdd2块新的硬盘，硬盘大小分别是3T和5T
对/dev/sdc进行分区

格式化硬盘分区并挂载
/dev/sdc1挂载到/data目录下

格式化/dev/sdc2并挂载到/data1

我们将/dev/sdd分区分成1个分区，并挂载到/data2上
