Description Michael Carney 2025-02-26 19:29:42 UTC

I tried to use restore (dump-0.4-0.57.b47.fc41) to recover from a data loss and encountered a failure:

restore > add .thunderbird
restore > extract
You have not read any volumes yet.
Unless you know which volume your file(s) are on you should start
with the last volume and work towards the first.
Specify next volume # (none if no more volumes): 1

In this instance, thunderbird was unable to recover the data. Either dump is silently corrupting its output data files, or restore is failing to properly restore the data. Both cases are serious problems. Every partition that I attempted to recover using restore had some number of these ftruncate errors.

Reproducible: Always

Steps to Reproduce:
1. Dump a partition
2. Try to restore files from dump file.
3. Observe error messages and lost data
Actual Results:  
Failure to restore files "successfully" dumped by dump-0.4-0.57.b47.fc41. Numerous ftruncate errors; a mixture of "Invalid argument" and "Bad file descriptor". Restored data was actually corrupted.

Expected Results:  
ext4 file system dumps created successfully by dump-0.4-0.57.b47.fc4 should likewise be successfully restored by same.
