[Bug 445592] Re: Transmission Ext4 / data loss?

[Bryan Quigley]

Would another solution be to use Persistent pre-allocation?

>From wikipedia "The ext4 filesystem allows for pre-allocation of on-disk
space for a file. The current methodology for this on most file systems
is to write the file full of 0s to reserve the space when the file is
created. This method would no longer be required for ext4; instead, a
new fallocate() system call was added to the Linux kernel for use by
filesystems, including ext4 and XFS, that have this capability. The
space allocated for files such as these would be guaranteed and would
likely be contiguous. This has applications for media streaming and
databases."

As my other understanding from the error message and the above, is that
it lost data because they were stored in different places.  Then ext4
filecheck cleared them all, because they weren't properly recorded in
ext4s records.  If all space is alloted ahead of time all data actually
written to disk will always be recoverable by transmission.
