Linux file systems are inspected and repaired using which utility?
Show answer Hide answer
Answer: C. fsck
Explanation
The fsck utility checks filesystem consistency and repairs structural errors automatically. Running this command scans superblock data, inodes, and directory allocation tables. System administrators rely on this tool to restore damaged filesystems after unexpected shutdowns. Unclean unmounts can leave filesystems in an inconsistent state risking data corruption. File system consistency checks compare metadata records against actual stored data blocks. Automated scripts run this utility during system boot sequences when faults are detected.
Emergency maintenance modes often require manual execution of filesystem checks on damaged disks. Preventive system administration includes periodic checks of storage integrity to prevent failures. Server reliability depends on proper error correction tools maintaining healthy storage volumes. Option mkfs is used to create new filesystems rather than inspecting existing ones. Option fdisk partitions storage drives rather than repairing file system structures. Option mount attaches storage volumes to the directory tree instead of checking consistency.
