Configuring Disk Quota

To implement file quota we need to edit /etc/fstab file and add the usrquota and grpquota option to the partition for which you want to enable quotas

#vi /etc/fstab

/dev/VolGroup00/LogVol00 /ext3 defaults,usrquota,grpquota 11

save the file

Remount the filesystem

#mount -o remount

or if we have entered more than one filesystem in the fstab file then to remount all the filesystem

#mount -a remount

Run quotacheck command to check for an errors on the filesystem with quota check

#quotacheck -augmv

Syntax info are as follows:

a= perform quotacheck on all filesystems
m= the filesystem should not be mounted as read-only mode
u & g= tells to check for users and groups

Turn on the quota

#quotaon -augmv

Apply the quota for a particular user

#edquota -u sushanth

Apply quota for particular group

#edquota -r susgrp
