The generic 'fsck' command will attempt to detect the filesystem type, or it will accept parameters specifying the type. 'e2fsck' is essentially a shortcut saying it's an ext2 filesystem. They all behave the same way and check the filesystem for errors.

Automatically repair the file system. If user intervention is required, e2fsck indicates the unfixed problem in its output and reflects this status in the exit code. # e2fsck -p block-device

2024年7月29日 · The e2fsck command is an essential utility for checking and repairing ext2, ext3, and ext4 file systems in Linux. This article will guide you through the basics to advanced usage of an e2fsck command line in linux, helping you maintain the integrity of your file systems effectively. What is e2fsck command?

2018年5月26日 · fsck is a wrapper for the filesystem-specific fsck.* family of tools. They can be used interchangeably with one caveat (from the fsck manpage): Options which are not understood by fsck are passed to the filesystem-specific checker.

2013年8月20日 · If e2fsck says output from a mounted file system isnt to be trusted, then how does systemd generate log messages from fs errors?

2024年7月31日 · The e2fsck utility is primarily used to check and repair ext2, ext3, and ext4 filesystem issues and inconsistencies. But it can help correct errors related to bad sectors when we use the -c option. Before running e2fsck , let’s ensure that the file system is unmounted to prevent any data corruption:

-C fd This option causes e2fsck to write completion information to the specified file descriptor so that the progress of the filesystem check can be monitored. This option is typically used by programs which are running e2fsck.

On modern systems, you definitely want e2fsck -c for a bad blocks check. If you're running an awesome system such as Debian or Ubuntu, you should have e2fsck-static installed -- and bash-static, as a bonus -- so you can just easily copy the binary to a safe partition and run it from there.

e2fsck is a command used to check a Linux second extended file system (ext2fs). E2fsck also supports ext2 filesystems containing a journal, which are also sometimes known as ext3 filesystems. The command automatically saves the bad blocks found into the filesystem, so that those parts of the hard drive are no longer used.

This option causes e2fsck to use badblocks(8) program to do a read-only scan of the device in order to find any bad blocks. -p: Automatically repair ("preen") the file system. -v: Verbose mode. -y: Assume an answer of 'yes' to all questions.
