Learning notes for ubuntu Disk Management

Method 1: ubuntu Disk Management Command

Umount/mnt uninstall

Mount/dev/sda1/mnt loading

Fdisk-l View disk information

Df/boot: check which partition of the boot folder belongs to the disk

Df-h View disk usage

Method 2: ubuntu disk management tool GNOME Disks 3.8.2

GNOME Disks is the default disk and media manager software for Ubuntu. It allows you to perform many operations on the disk, including formatting, status, deep partitioning, and other related practical operations. The interface is friendly and easy to operate.

GNOME Disks 3.8.2 has been logged on to Ubuntu13.10. Through regular updates, features of versions later than version 3.6 are enriched.

A new device is prompted at the top.

Disk format option changed!

Method 3: ubuntu disk management tool gparted

Gparted is a good graphical disk management tool on Ubuntu (installed using "sudo apt-get install gparted"). It is intuitive and easy to use and is suitable for beginners.

Disk/dev/sdb doesn' t contain a valid partition table

From the display information, two hard disks are available:/dev/sda and/dev/sdb. The corresponding capacity is 42.9G and 10.7G. /Dev/sdb is not partitioned yet.
2) partition/dev/sdb
Ray @ ray-ubuntu :~ $ Sudo fdisk/dev/sdb

WARNING: DOS-compatible mode is deprecated. It's stronugly recommended
Switch off the mode (command 'C') and change display units
Sectors (command 'u ').
Command (m for help): m
Command action
A toggle a bootable flag
B edit bsd disklabel
C toggle the dos compatibility flag
D delete a partition
L list known partition types
M print this menu
N add a new partition
O create a new empty DOS partition table
P print the partition table
Q quit without saving changes
S create a new empty Sun disklabel
T change a partition's system id
U change display/entry units
V verify the partition table
W write table to disk and exit
X extra functionality (experts only)
Select n to add a new partition. Then select the default settings. Select w, execute the operation, and exit.
Check the hard disk information again.

It is confirmed that the new hard disk partition is successful.
2. Partition formatting
Format the file system to ex3.

Ray @ ray-ubuntu:/dev $ sudo mke2fs-j sdb1
[Sudo] password for ray:

Filesystem label =
OS type: Linux
Block size = 4096 (log = 2)

This filesystem will be automatically checked every 35 mounts or
180 days, whichever comes first. Use tune2fs-c or-I to override.
Note: You can also use the command "sudo mkfs. ext3/dev/sdb1" to format the ex3 file system"
Check the partition format:
Ray @ ray-ubuntu :~ $ Sudo df-hT/dev/sdb1
Filesystem Type Size Used Avail Use % Mounted on
/Dev/sdb1 ext3 9.9G 151 M 9.2G 2%/media/sdb1

3. How to automatically mount www.111cn. Net
Before talking about how to automatically mount a disk, let's talk about how to manually mount the disk.
First, create the disk-2 folder in the/media/Directory (of course, you can specify any mount point ):
Ray @ ray-ubuntu:/media $ sudo mkdir disk-2

Ray @ ray-ubuntu:/media $ ls-al
Total 16
Drwxr-xr-x 4 root 4096.
Drwxr-xr-x 22 root 4096 ..
Drwxr-xr-x 2 root 4096 disk-2
Lrwxrwxrwx 1 root 7 2010-08-16 16:34 floppy-> floppy0
Drwxr-xr-x 2 root 4096 2010-08-16 16:34 floppy0

Ray @ ray-ubuntu:/media $ sudo mount/dev/sdb1 disk-2
Ray @ ray-ubuntu:/media $ cd disk-2
Ray @ ray-ubuntu:/media/disk-2 $ ls
Lost + found

In this way, the mount is successful.
1) automatic startup
The script file is/etc/fstab and is added as follows:
# Mount the second hard disk
/Dev/sdb1/media/sdb1 ext3 defaults 0 0

The six parameters are:
<File system> <mount point> <type> <options> <dump> <pass>
The meaning of the first three parameters is obvious.
Options: specify that the file system to load the device is a specific parameter option, multiple parameters are separated by commas. Most systems can use "defaults" to meet their needs.
Other common options include:
Ro loads the file system in read-only mode
Sync does not buffer write operations on the device, which can prevent file system damage during abnormal shutdown, but reduces the computer speed.
User allows normal users to load the file system
Quota forces disk quota limit on this file system
Noauto no longer uses the mount-a command (for example, when the system is started) to load the file system
Dump: This option is used by the "dump" command to check how often a file system should be dumped. If you do not need to dump, set this field to 0.
Pass: This field is used by the fsck command to determine the sequence of the file system to be scanned at startup. The value of the "/" pair of the root file system should be 1, other file systems should be 2. If the file system does not need to scan at startup, set this field to 0.
