http://forums.fedoraforum.org – I have setup a group quota for better disk usage. What i am doing is to setup a quota with Samba share. I created user1,user2 and group project1 which belongs to /home/project1 dir. Quota is implemented on project1 group to write 100 MB on this share and This is working fine if a user1 and user2 which are belonging to project1 group under /home/project1. They can not write up to 100 MB on this share. But the challenge is this when i am going to create another group project2 and created users user4 and user5 which belongs to this group and having home directory /home/project2 and samba sha (HowTos)
