aha !
so as you've created that mountpoint as root, I guess /home2/ looks like this:
Code:
drwxr-xr-x root root home2
normal users are member of the users group, so in this case they don't have write access to that folder (users are not members of the root group and 'others' only get r-x here).
so you could do sth like this:
Code:
mount /dev/'whatever fits for your case' /home2/
chown root.users /home2/
chmod 775 /home2/
by this you grant every member of the users group rwx permissions on that folder.
if you'd like to restrict file deletion to the owner of a file you can set the +t flag like on the /tmp/ folder with:
hope it works
