Frustrating quota error

Everywhere I look for the answer to this I find incomplete threads with no resolution. If cPanel support would like to jump in I will be glad to follow instructions to figure this out.

I've got a Linode VPS running Centos 6.2 and current cPanel Release (WHM 11.30.6 (build 3) CENTOS 6.2 i686 xenpv on server). My cPanel error log is filled with this:

Code:

[2012-02-22 02:30:27 -0500] info [pkgacct] Quotas are not enabled

When I try quotacheck I get this:

Code:

root@server [~]# quotacheck -a
quotacheck: Cannot stat() mounted device /dev/root: No such file or directory

When I try fixquotas I get this:

Here is my fstab and mtab:
Code:

# /etc/fstab
#
# Accessible filesystems, by reference, are maintained under '/dev/disk'
# See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info
#
/dev/xvda / ext3 defaults,usrquota,noatime,errors=remount-ro 1 1
/dev/xvdb swap swap defaults 0 0

devpts /dev/pts devpts gid=5,mode=620 0 0

proc /proc proc defaults 0 0
/usr/tmpDSK /tmp ext3 defaults,noauto 0 0
/tmp /var/tmp ext3 defaults,usrquota,bind,noauto 0 0

Code:

/dev/xvda / ext3 rw,noatime,usrquota,errors=remount-ro 0 0
proc /proc proc rw 0 0
sysfs /sys sysfs rw 0 0
devpts /dev/pts devpts rw,gid=5,mode=620 0 0

/tmp /var/tmp none rw,noexec,nosuid,bind 0 0

All the disk usage notifications are set to on (default settings) under "Main >> Server Configuration >> Tweak Settings."

I've read in some places that /dev/root was deprecated. Others suggested linking /dev/xvda with /dev/root. I tried that and the /dev/root warnings went away but quotacheck warned:

Code:

root@server [~]# quotacheck -a
quotacheck: Quota for users is enabled on mountpoint / so quotacheck might damage the file.
Please turn quotas off or use -f to force checking.

so I removed the link. Fstab looks right to me but at this point I'm not sure about anything. I would really appreciate some help with this. Thanks in advance.
