[UnderHost]

There are many possible causes of this issue, however most relate to quotas being enabled on the filesystem itself.

Some ways to check the most common errors are:

Quotas enabled in the filesysem

By default, quoatas are enabled in the kernel on all UnderHost Linux and FreeBSD kernels. If you've compiled/installed your own kernel, you'll need to verify that quotas are enabled.

--- FreeBSD systems will need to add "options QUOTA" to their kernel configuration and recompile. They will then need to add "enable_quotas="YES"" to their /etc/rc.conf file.

--- To enable quotas on a certain partition, one will need to modify the /etc/fstab file by adding usrquota (or grpquota if one desires the quota to pertain to an entire group rather than an individual user) to the options column (e.g. "LABEL=/home /home ext3 defaults,usrquota 0 0").

[root@linux-test-server ~]# cat /etc/fstab
# This file is edited by fstab-sync - see 'man fstab-sync' for details
LABEL=/                 /                       ext3    defaults,usrquota        1 1
LABEL=/boot             /boot                   ext3    defaults        1 2
none                    /dev/pts                devpts  gid=5,mode=620  0 0
none                    /dev/shm                tmpfs   defaults        0 0
none                    /proc                   proc    defaults        0 0
none                    /sys                    sysfs   defaults        0 0
LABEL=SWAP-sda2         swap                    swap    pri=0,defaults        0 0
/usr/tmpDSK             /tmp                    ext3    defaults,noauto        0 0
/tmp             /var/tmp                    ext3    defaults,bind,noauto        0 0
[root@linux-test-server ~]#

--- Once those entries are added, a reboot of the server should resolve the issue.

Run /scripts/fixquotas

Cpanel has it's own tools to repair the quotas for it's accounts. the command

#/scripts/fixquotas

run through ssh may resolve the issue.

Repquota

The command

#repquota -ua

will tell you if quotas are being reported for OS users at all.

Quotacheck

The command

#quotacheck -fv /home

will display the quotas for that filesystem, however the partition has to be unmounted first. It's best to do this from Single User mode.
