Reserving space in ext2 or ext3 for a big file.



Hi all.
I have the follow problem, my software need make a file with 4GB
and I need reserve space before the file generation finishs.
I'm testing the quota command for files, but its not works very
well in redhat7.2 for example.
Exists a command to reserve a space for a file in ext2 or ext3
filesystens?

Thanks for all in advance...
