A data salvage tool from a damaged xfs file system

xfs_salvage

A data salvage tool from a damaged xfs file system. This has a possibility to recover a (partial) list of files and their contents from half-broken xfs drives even after xfs_repair -L trials fail. ABSOLUTELY NO WARRANTY.

Prerequisite

• xfs_metadump
• xfs_mdrestore
• xfs_db
• (slightly modified) xfs_undelete

Usage

1. First extract xfs metadata with xfs_metadump:

$ sudo xfs_metadump -w -o -a /dev/BROKEN_DRIVE drive.metadump.ao
$ xfs_mdrestore drive.metadump.ao drive.metadump.ao.img

Change BROKEN_DRIVE for your drive point.

2. Second recover the file path list from the dumped metadata:

$ python xfs_inode_salvage.py
    --img_file drive.metadump.ao.img \
    --excludes "['uninteresting folders','src','bin','etc']" \
    --skip_dot_dir

The results are tuple of filetype, inode and path.

3. Finally, get the original file contents with the (slightly modified) xfs_undelete by recovered inodes.
