Display block
debugreiserfs -1 [block_number] [/dev/sda1]
Scan for reiserfs
debugreiserfs -S [/dev/sda1]
Unpack metadata
debugreiserfs -u [/output/dir] [/dev/sda1]
说明
debugreiserfs is a debugging tool for ReiserFS filesystems. It displays internal filesystem structures including the superblock, journal, and B+ tree nodes without mounting the filesystem. The tool is valuable for diagnosing ReiserFS problems, understanding filesystem structure, and recovering data. It can dump the entire filesystem tree, examine specific blocks, and extract metadata for analysis. debugreiserfs operates on unmounted filesystems and provides low-level access to ReiserFS internals that are not visible through normal filesystem operations.
