Can you post the restore log of those files?

Thanks.

Thanks! I Rsync'd, switched to DEBUG and restored a third "Corrupted" file. Here are the results.



Once again, the file ended up being 5.5 GB instead of 8.2 GB.

As suspected, the files are not being restored properly (most likely due to the RAID being out of synch).



I just had to to fix the logging on the restore task as a bug prevented it from logging subsequent restore failures.
When the restore operation completed, you should have seen a report of how many files were not successfully restored (marked at corrupted).

I would ignore corruption reports for now until the next release.
I think we have cases of false positive as some files are being picked while still being recorded to.
