jfs_fscklog

jfs_fscklog log_file

log_file
    The path to the log file generated by `fsck.jfs`.

The `jfs_fscklog` command analyzes logs generated by the JFS filesystem checker (`fsck.jfs`). It parses the log file and provides a summary of the operations performed during the filesystem check, including information about errors found and repairs made. This allows administrators to review the actions taken by `fsck.jfs` and ensure the integrity of the filesystem after a check. This tool helps in understanding the level of file system corruption and recovery process of JFS file system.

The tool is essential for system administrators for analyzing JFS filesystems and ensuring they were properly fixed after a file system check.

The `jfs_fscklog` command will output details of the JFS file system check from the supplied log file.

The output will include:

• superblock information
• Inode checks
• Directory Checks
• Other important information

The `jfs_fscklog` command was developed as part of the JFS filesystem tools. It provides a way to interpret the fsck.jfs tool output which can otherwise be hard to understand. It has been available for a long time with only slight changes over the years to keep up with the underlying fsck.jfs tool.
