You mean lustre client? Our lustre client work as a web server for
downloading file, it's using ssd drive and the free space is quite small,
just few Gbs, but it's serving many 10GB size file quite well. If the
joining file process is on the client, how the big file can fit the poor
free space well like this ? Could you please explain it for me ?

Best regards
