Hi everyone

I'm wondering if it's possible to mount multiple devices on the same mount point.
I wish to have both devices (hda2 and hda4) mounted on the root dir.
I tried to just mount the two device on the same point.
Mount command issued by itself:
bash-2.05b# mount
/dev/hda2 on / type ext3 (rw)
/dev/hda4 on / type ext3 (rw)
Then I checked the diskspace using df:
bash-2.05b# df
Filesystem 1k-blocks Used Available Use% Mounted on
/dev/hda2 4730632 2577056 1909388 58% /
/dev/hda4 4730632 2577056 1909388 58% /
It is showing the same size, anyone have a clue on how to solve this?
I tried to copy over a large file and the diskspace ran out at 100% even though there's enough space to save it on hda4.
Thanks
