You are asked to assist a user who claims that file system issues are being reported when the computer is booting up. You notice issues on sda2 after restarting the user's computer. Change to single user mode and execute fsck /dev/sda2 to fix the issue.
Which of the following strategies will check the file system on sda2 and fix the errors?
Switch to single user mode, then execute fsck /dev/sda2. On your file system, you can perform a search using the find command. Finding and processing matches, such as files, directories, symbolic links, system devices, etc., within the same command is possible when using the -exec flag (find -exec).
Mount the volumes' file systems after creating them. As ext3's replacement, ext4 (fourth extended filesystem) was created as a journaling file system for Linux.
To inspect and repair inconsistent file systems interactively, use the fsck command. As part of system initialization, it is crucial to execute this command on each file system. The device file (such as /dev/hd0) on which the file system is stored must be readable.
Therefore the correct answer is change to single user mode and run fsck /dev/sda2.
