chown : Could not modify the ownership ... problem

[Sharpi]

First of all, I must say that I'm totally newbie to Gentoo and *nix in general.

So here is my problem :
i'm trying to install a cvs server on my laptop and I have to change the owner of the repository folder (chown -R cvs.cvs /mnt/data/cvs/repository)
But this folder is on another patition and is FAT32. When trying this, under Konqueror i get the following message : "Could not modify the ownership of file /mnt/data/cvs/repository. You have insufficient access to the fiel to perform the change). And I'm logged in as root. Also, it's the same if I create a file on this partition and try to change its owner or group.

Here is the line of my fstab that is used dto mount the partition :
/dev/hda2 /mnt/data vfat defaults,uid=0,gid=100,umask=0,rw 0 0

Any clue of why i get this ?

Thanks

If it's FAT32 then you can't use permissions.

Permissions are for *nix partitions only.

Ok thanks, it was simple
So I will have to put my CVS repository in another place.
