cd [hsphere_partition]
rm -f aquota.user quota.user
4) Update aquota.user and quota.user files::
quotacheck -m [hsphere_partition]
  * ignore "-m" for Free BSD
5) Turn on disk quota:
quotaon [hsphere_partition]
6) Then log into CP server as root and change to cpanel user:
su - l cpanel
7)Reset user defined quotas:
java psoft.hsphere.tools.SetQuota -lid 335[logical_server_id]
