Assign disk quota to a user

Code:

sudo apt-get install quota

then edit your /etc/fstab .. find the partition you want to put quotas on and add in ursquota and grpquota .. for example

Code:

/dev/hda3       /home           ext3    defaults,usrquota,grpquota        0       2

reboot.. then assuming the partition is hda3

Code:

sudo edquota -u johnsie -f /dev/hda3

make it look like this

Code:

Disk quotas for user johnsie (uid 100):
  Filesystem                   blocks       soft       hard     inodes     soft     hard
  /dev/hda3                         0     31457280     31457280          0        0        0

home my calculations are correct

OK, save that file... now do

Code:

sudo edquota -t -f /dev/hda3

set grace periods to 0 seconds like this

Code:

Grace period before enforcing soft limits for users:
Time units may be: days, hours, minutes, or seconds
  Filesystem             Block grace period     Inode grace period
  /dev/hda3                  0seconds               0seconds

again, save the file... and finally

Code:

quotaoff -a

and..

Code:

quotaon /dev/hda3
