The “hard limit” (hard =) specifies the absolute limit on the disk usage a quota user can't go beyond it. Take a note  that the “hard limit” value works only when the “grace period” parameter is set. The grace period parameter The “grace period” parameter allow you to set a time limit before the soft limit value is enforced on a file system with quota enabled (see the soft limit above for more information). For example this parameter can be used to warn your users about a new politic that will set a quota of 5MB of disk space in their home directory in 7 days. You can set the 0 days default part of this parameter to any length of time you feel reasonable. The changes of this setting require two steps as follow (in my story example I assume 7 days). Step 1 · Edit the default grace period parameter, by using the following command: [root@deep /]# edquota -t Time units may be: days, hours, minutes, or seconds  Grace period before enforcing soft limits for users: /dev/sda6: block grace period: 0 days, file grace period: 0 days  Step 2 · Modify the grace period to 7 days. Change or set the following parameters in the vi editor: Time units may be: days, hours, minutes, or seconds  Grace period before enforcing soft limits for users: /dev/sda6: block grace period: 0 days, file grace period: 0 days  To read: Time units may be: days, hours, minutes, or seconds  Grace period before enforcing soft limits for users: /dev/sda6: block grace period: 7 days, file grace period: 7 days  NOTE: The command “edquota -t” edits the soft time limits for each file system with quota enable. Assigning quota for a particular group If for example, you have  a group with the group id “webusers” on your system. The following command takes you into the vi editor to edit quota for group “webusers” on each partition that has quota enabled: · To edit and modify quota for group “webusers”, use the following command: [root@deep /]# edquota -g webusers Quotas for group webusers: /dev/sda6: blocks in use: 6, limits (soft = 0, hard = 0)         inodes in use: 6, limits (soft = 0, hard = 0)
