Linux partition and Mount graphic tutorial

1. after adding a new hard disk, you can use fdisk-l to view and confirm the new hard disk. In linux, device files are stored in/dev: 1) IDE hard disk is represented as hd, SCSI is represented as sd, 2) The first block is represented as. The second part is B, and so on. For example, the hard disk of the first IDE is hda3. the partition is represented by numbers. The primary partition is 1--4, and the logical partition is 5.

 

1. after adding a new hard disk, you can use fdisk-l to view and confirm the new hard disk.

  In linux, the device files are stored in/dev:

    1) IDE hard disk is represented as hd, SCSI is represented as sd,

     2) The first part is represented by. The second part is B, and so on. For example, the hard disk of the first IDE is hda.

    3) partitions are represented by numbers. The primary partition is 1--4 and the logical partition is 5--X. For example

       Primary partitionsIt is hda1, the first logical partition is hda5, and the second logical partition is hda6. This

       And so on.

    4) device: device name of the partition

       Boot: Whether to start the boot partition

       Start: number of start columns in a partition

       End : Number of ending cylinders in a partition

       Blocks: partition size

       Id  : ID of the partition

       System: partition type

2. this is a partition ID and the corresponding file system type. in linux, there are only four commonly used types. what I check is.

 82 linux swap (Swap partition system) this partition type is used to solve the physical memory shortage, similar to the virtual memory in windows.

 83 linuxEXT3   Default partition system type in linux

 8e linuxLVM   LVM Logical Volume in linux

 5Linux extended partitions

3. use fdisk to enter the interactive partition management interface, as shown in. Press m to enter the help page.

4. I will organize the information on this interface below. you can learn it by comparison. Common options are highlighted in blue.

5. look at the table above and start partitioning ...... P. check the current partition ......

6. create a 20g primary partition.     ECreate an extended partition
                              PCreate a primary partition

                             Parfitionnumber primary partition number

                              Number of cylinder at the beginning of Firstcylinder. the default value is 1. press Enter.

                             LastcylinderPartition size

7. view the existing primary partition ......

8. create a 40 GB extended partition.

9. now we can see that we have created an extended partition/dev/sdb2.

10. create a logical partition on the extended partition we have created. Logical

11. now we can see the created logical partition.

12. delete a partition. Use d

13. use w to save the created partition and exit ......

14. use fdisk-l again to see the created partition.

15. format the partition with mkfs ...... You can first check the mkfs related files ......

16. when mkfs does not match any options, you can format the specified partition according to the allocated system type.

  -T can be used to specify the type.

17. df is used to view mounted devices and no/sdb is found. Therefore, we need to mount them before using them ......

18. Mount/dev/sdb5.. use df to check whether the disk has been mounted.
