Quota showing "Unlimited " in WHM !!!!!

For recently created users, quota is not working properly in WHM.

While running #  /scripts/fixquotas , error obtained as follows:

Resetting quota for user1 to 10000 M
edquota: Quota write failed (id 517): Invalid argument
Resetting quota for user2 to 300 M
edquota: Quota write failed (id 507): Invalid argument
........................................

SOLUTION :

Run the following command:

#  quotacheck -vagum

 v :  quotacheck report its operation as it progresses

 g :  Only group quotas listed in /etc/mtab or on the filesystems specified  are  to        be checked

u :  Only user quotas listed in /etc/mtab or on the filesystems specified will be checked        

m : Don't try to re-mount file system as Readonly.

a  : Check all mounted non-NFS  filesystems in /etc/mtab

It will take a long time to complete the quotacheck. After completing the quotacheck, run /scripts/fixquotas 

The issue has been fixed now..!!!!!!!
