The use of the Linux dump command, in view of this problem, this article introduces the corresponding analysis and answer in detail, hoping to help more partners who want to solve this problem to find a more simple and easy way.

The Linux common command e2fsck command is used to check whether partition using the Linux ext2 file system is working properly.

Syntax e2fsck [- pacnydfvFV] [- b superblock] [- B blocksize] [- l |-L bad_blocks_file] [- C fd] device parameter description:

Device: hard disk partition to be checked, for example: / dev/sda1

-a: check the partition and fix it automatically if there is a problem, which is equivalent to the function of-p

-b: set the location where the superblock is stored

-B: sets the size of the unit block

-c: check whether the partition has bad tracks

-C file: save the results of the check to file for viewing

-d: print the debug results of e2fsck

-f: mandatory inspection

-F: clear the buffer cache of device before starting the check to avoid errors

-l bad_blocks_file: add block data with bad tracks to bad_blocks_file

-L bad_blocks_file: the block data for setting bad tracks is stored in bad_blocks_file. If there is no such file, it will be generated automatically.

-n: open the file system in read-only mode

-p: check the partition and fix it automatically if there is a problem

-v: detailed display mode

-V: shows the current version of e2fsck

-y: pre-set all inspection questions to be answered [Yes]

The instance checks whether / dev/hda5 is normal, fixes it automatically if there is any exception, and sets the answer [Yes] if there is a question:

E2fsck-a-y / dev/hda5 Note:

When most people use e2fsck to check the hard disk partition, it is usually a special case, so it is best to check the partition umount first, and then execute the e2fsck. If you have to check / time, please enter the singal user mode and then execute.
