> RaidShell currently has an option to recover a file and return the path to the recovered file. The administrator can then rename the recovered file to the damaged file.
> The problem with this is that the file metadata is altered, specifically the modification time. Instead we need a way to just repair the damaged blocks and send the fixed blocks to a data node.
> Once this is done, we can put automation around it.
