Quota is implemented on /data but not working properly. Find out the
Problem and implement the quota to user1 to have a soft limit 60 inodes
(files) and hard limit of 70 inodes (files).
Quotas are used to limit a user’s or a group of users’ ability to consume disk space. This prevents
a small group of users from monopolizing disk capacity and potentially interfering with other users
or the entire system. Disk quotas are commonly used by ISPs, by Web hosting companies, on
FTP sites, and on corporate file servers to ensure continued availability of their systems.
Without quotas, one or more users can upload files on an FTP server to the point of filling a
filesystem. Once the affected partition is full, other users are effectively denied upload access to
the disk. This is also a reason to mount different filesystem directories on different partitions. For
example, if you only had partitions for your root (/) directory and swap space, someone uploading
to your computer could fill up all of the space in your root directory (/). Without at least a little free
space in the root directory (/), your system could become unstable or even crash.
You have two ways to set quotas for users. You can limit users by inodes or by kilobyte-sized disk
blocks. Every Linux file requires an inode. Therefore, you can limit users by the number of files or
by absolute space. You can set up different quotas for different filesystems. For example, you can
set different quotas for users on the /home and /tmp directories if they are mounted on their own
Limits on disk blocks restrict the amount of disk space available to a user on your system. Older
versions of Red Hat Linux included LinuxConf, which included a graphical tool to configure quotas.
As of this writing, Red Hat no longer has a graphical quota configuration tool. Today, you can
configure quotas on RHEL only through the command line interface.
1. vi /etc/fstab
/dev/hda11 /data ext3 defaults,usrquota 1 2
2. Either Reboot the System or remount the partition.
Mount -o remount /dev/hda11 /data
3. touch /data/aquota.user
4. quotacheck -ufm /data
5. quotaon -u /data
6. edquota -u user1 /data
and Specified the Soft limit and hard limit on opened file.
To verify either quota is working or not:
Soft limit specify the limit to generate warnings to users and hard limit can’t cross by the user. Use
the quota command or repquota command to monitor the quota information.
