Disk partition under linux

Create partition---》Format---》Mount and use

1. Create partition

[root@localhost ~]# fdisk -l Check the partition status of the disk

[root@localhost ~]# fdisk /dev/sdb

Command (m for help): m Get help and see which commands can be used

Command (m for help): n Create a new partition

Command action

e extended

p primary partition (1 -4)

p #Primary partition

Partition number (1-4): 1 Primary partition number

First cylinder (1-10443, default 1):

Using default value 1

Last cylinder, +cylinders or +size{K,M,G} (1-10443, default 10443): +10G #Specify the size of the partition

Command (m for help): p Output

Command (m for help): w Exit and save

The partition table has been altered!

Calling ioctl() to re-read partition table.

Syncing disks.

2.Format

[root@localhost ~]# mkfs.ext4 /dev/sdb1 format Convert the sdb1 partition to

mke2fs 1.41.12 (17-May-2010)

Filesystem label=

OS type: Linux

Block size=4096 (log=2)

Fragment size=4096 (log=2)

Stride=0 blocks, Stripe width=0 blocks

655776 inodes, 2622603 blocks

131130 blocks (5.00%) reserved for the super user Reserve 5% of the space for the super user, when the disk usage is 100% At this time, the root user can still enter the system.

81 block groups

32768 blocks per group, 32768 fragments per group

Writing inode tables: done

Creating journal (32768 blocks): done

Writing accounting superblocks and filesystem information: done

This filesystem will be automatically checked every 32 mounts or

180 days, whichever comes first. Use tune2fs -c or -i to override.

3. Create a new mount directory

mkdir /music Create a new mount directory

4. Mount using

mount /dev/sdb1 /music mounts a new partition

5. Automatically implement when booting

echo "mount /dev/sdb1 /music" >>/etc/rc.local

The function of the /etc/rc.local file is: The system will automatically execute the commands in this file when it is turned on. When installing the system, how many partitions will it be divided into?

/ As large as possible

swap twice the memory of

/home

/boot 200M is enough
