Tips for two points:
* The newly added hard drive needs to restart the server fdisk-l to see
* To use the root account for the following operations
That's about it. View-partition-format-mount-restart auto mount
1. Restart the server after adding the hard drive to view

2. Partitioning
Fdisk can use the M command to see the internal commands of the FDISK command;
A: The command specifies the boot partition;
D: command to delete an existing partition;
L: command displays a list of partition ID numbers;
M: View the fdisk command help;
N: command to create a new partition;
P: command displays a list of partitions;
T: Command modifies the type ID number of the partition;
W: The command is to save changes to the partition table to make it work.
[Email protected] ~]# fdisk/dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF Disklabel
Building a new DOS disklabel with disk identifier 0x515ae162.
Changes'll remain in memory only, until the decide to write them.
After that, of course, the previous content won ' t is recoverable.
Warning:invalid flag 0x0000 of partition Table 4 would be a corrected by W (rite)
Warning:dos-compatible mode is deprecated. It ' s strongly recommended to
Switch off the mode (command ' C ') and change display units to
Sectors (Command ' u ').
Command (M for help): n
Command Action
E extended//Enter E to create an extended partition
P primary partition (1-4)// input P to create logical partition
P
Partition number (1-4): 1 // Enter the L hereand enter the logical partitioning phase
First cylinder (1-26108, default 1)://Note: This is the start value of the partition, it is best to press ENTER directly , if you enter a non-default number, will cause space waste;
Using Default value 1
Last cylinder, +cylinders or +size{k,m,g} (1-26108, default 26108): I'll go straight to the full use. Note: This is the definition of partition size, +200m is the size of 200M, of course, you can also be based on the P hint of the unit cylinder size to calculate, and then to specify the value of end. Look back to see how it is, or use +200m this method to add, this can be intuitive. If you want to add a 10G or so size partition, please enter +10000m;
Using Default Value 26108
Command (M for help): w// Last input W enter save .
The partition table has been altered!
Calling IOCTL () to re-read partition table.

After saving, check

3. Formatting
[Email protected] ~]#MKFS.EXT3/DEV/SDB1Note: The/DEV/SDB1 format as a ext3 type, confirm that I/dev/sdb1 above is a new 200GB hard drive, this step directly to the return, format will automatically jump out of

4. Mounting
--Create a directory, then mount it to the directory
[Email protected] ~]#Mkdir/data
[Email protected] ~]#Mount/dev/sdb1/data
[Email protected] ~]# df-h
Filesystem Size used Avail use% mounted on
/dev/sda3 75G 21G 51G 29%/
Tmpfs 3.9G 0 3.9G 0%/dev/shm
/DEV/SDA1 194M 25M 160M 14%/boot
/DEV/SDB1 197G 188M 187G 1%/data
5, restart the boot automatically mount, to write to fstab inside (that is the last line), or restart after the new home to find the hard drive
