Linux disk partition formatting

1. How do I view disk information?
2.vmware add hard drive how to identify?
3. How do I create a partition?

To view disk information:
Fdisk-l
The information for each disk and the partition information on the disk are displayed

Add a hard drive in VMware

Add a disk on boot, and then use Fdisk-l to see that there is no automatic recognition and that a restart is required
Remove the hard drive while booting up, and then use Fdisk-l to view the following issues

partitioning and formatting of disks
You need to partition a new disk after you have added it, you can use the command fdisk (fixed disk)
FDISK [device]

650) this.width=650; "title=" image_thumb[11] "style=" border-top:0px; border-right:0px; Background-image:none; border-bottom:0px; padding-top:0px; padding-left:0px; margin:0px; border-left:0px; padding-right:0px "border=" 0 "alt=" image_thumb[11] "src=" http://img1.51cto.com/attachment/201408/30/8926377_ 1409415309wgwg.png "" 380 "height=" 319 "/>
Enter in interactive mode: M get help
To create a new partition:
Create Primary partition: M (m for help)-->n (add a new partition)-->p (primary partition (1-4))
Create extended partition: M (m for help)-->n (add a new partition)-->e (Extended)

Note: You can create up to four primary partitions and optionally create three primary partitions and one extended partition
It will look like this when it's created:
650) this.width=650; "title=" image_thumb[13] "style=" border-top:0px; border-right:0px; Background-image:none; border-bottom:0px; padding-top:0px; padding-left:0px; margin:0px; border-left:0px; padding-right:0px "border=" 0 "alt=" image_thumb[13] "src=" http://img1.51cto.com/attachment/201408/30/8926377_ 1409415311intc.png "" 394 "height=" 183 "/>

You need to format the partition after creating the partition, that is, to create the file system, using the command mkfs (make file)
MKFS options:
-t:fstype file system type, for example: Mkfs-t Ext4 is also equivalent to MKFS.EXT4
Mkfs.ext4/dev/sdc1
Mkfs.ext4/dev/sdc2
Mkfs.ext4/dev/sdc3

Mount Partition
Temporary mount:
Create three directories
Mkdir-p/mydata/data{1,2,3}
then mount them separately.
Mount-t ext4/dev/sdc1/mydata/data1
Mount-t Ext4/dev/sdc2/mydata/data2
Mount-t ext4/dev/sdc3/mydata/data3

Automatic mount on Boot:
Need to edit the/etc/fstab file to write mount information to

Description
The contents of the file are divided into six parts with blank characters:
1. Mounted Devices
Device file, volume label, UUID
2. Mount point
3. File system type
4. Mount selection, defaults means use default option, multiple options comma delimited
5. Dump frequency: How long does the dump take to make a backup
0: Never Back up
1: Daily backup
2: Backup every other day
6. Self-Test order:
Self-test, check whether the file is complete, remove the incomplete files
0: No detection
1: The first detection, usually the root file system
