Is WHM showing wrong disk usage for any accounts or the corresponding packages ? Usually when this issue pops up, we run the following command via back-end :
# /scripts/fixquotas
Did this give rise to another error ? Something like,
Reading package package_name edquota: Quota write failed (id 507): Invalid argument
Fix this issue by running the following command :
# /sbin/quotacheck -vguma
where,
-v :- quotacheck reports 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 are to be checked. This is the default action -m :- Don’t try to remount filesystem read-only -a :- Check all mounted non-NFS filesystems in /etc/mtab
Once the above one is completed, run # /scripts/fixquotas
