Improving ext4: bigalloc, inline data, and metadata checksumsImproving ext4: bigalloc, inline data, and metadata checksumsPosted Dec 12, 2011 16:15 UTC (Mon) by nye (guest, #51576)In reply to: Improving ext4: bigalloc, inline data, and metadata checksums by mpr22 Parent article: Improving ext4: bigalloc, inline data, and metadata checksums
>Did anyone ever fix the ReiserFS tools to the point that you could safely fsck a ReiserFS volume that contained an uncompressed ReiserFS image?
The existing replies have basically answered this, but just to make it clear:
You could always do that.
Reiserfs *additionally* came with an *option* designed to make a last-ditched attempt at recovering a totally hosed filesystem by looking for any data on the disk that looked like Reiserfs data structures and making its best guess at rebuilding it based on that.
Somehow the FUD brigade latched on to the drawbacks of that feature and conveniently 'forgot' that it was neither the only, nor the default fsck method.

In my long-ago experience, reiserfsck --fix-fixable did absolutely nothing to improve a broken filesystem, and --rebuild-tree was the only way to get anything out. Maybe you got very lucky?

Maybe I did. Or maybe you got unlucky. Most of the people commenting on it though *never tried*; they just heard something bad via hearsay and parrotted it, and that just gets to me.
