Bright:Setup user quotas

• Lets apply user quotas to /home on a Bright headnode
• Running Centos 6.5
• Applying qoutas to an EXT3 filesystem

Setup quotas within /etc/fstab

• Need to add usrquota,grpquota to the /etc/fstab file for the home dir mount point
• Lets check the home mount point (in this instance its just / for bright)

[root@trainning ~]# df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/md126      426G   14G  392G   4% /
tmpfs            16G   84K   16G   1% /dev/shm
/dev/md125      496M   24M  447M   6% /boot

• Lets update the /etc/fstab file with the parameters usrquota,grpquota for user mount points.

[root@trainning ~]# cat /etc/fstab

• Remount the filesystem and verify the args in mtab

[root@trainning ~]# mount -o remount /
