18.9.1 Enabling Disk Quotas on File Systems

To enable user or group disk quotas on a file system:

Install or update the quota package:
```
# yum install quota
```
Include the usrquota or grpquota options in the file system's /etc/fstab entry, for example:
```
/dev/sdb1       /home        ext4    usrquota,grpquota   0 0
```
Remount the file system:
```
# mount -o remount /home
```
Create the quota database files:
```
# quotacheck -cug /home
```
This command creates the files aquota.user and aquota.group in the root of the file system (/home in this example).

For more information, see the quotacheck(8) manual page.
