- Added cross-references in troubleshooting.md and file-system-backup.md to the Write Sparse files documentation
- Documented how to use --write-sparse-files flag when restores fail due to disk space constraints
- Clarified important limitation: only works if PV had sparse files during backup that would free up space
- Removed enhanced error messages and code changes (documentation-only approach per feedback)
This addresses issue #2812 by providing clear guidance to users when restores fail due to disk space constraints.
