Initial Quota Setup does not works

Hello everyone!
i'm using cPanel since some day!
i'm not a hosting provider or something else i'm just private users!

i'm current on dedicate server!

i had some problem with Initial Quota Setup
at starting quota for cPanel users was working FINE, now it show Disk Space Usage NA / ∞ for every users

i tryed initial quota from whm

quotacheck: Cannot stat() mounted device /dev/root: No such file or directory
quotacheck: Cannot find filesystem to check or filesystem not mounted with quota option.

my current fstab

Code:

/dev/sda1       /       ext3    usrjquota=quota.user,jqfmt=vfsv0      0       1
/dev/sda2       /home   ext4    usrquota       1       2
/dev/sda3       swap    swap    defaults        0       0
proc            /proc   proc    defaults                0       0
sysfs           /sys    sysfs   defaults                0       0
tmpfs           /dev/shm        tmpfs   defaults        0       0
devpts          /dev/pts        devpts  defaults        0       0

i did a look to other topic i and nothing helped me to fix this problem

i also tryed /scripts/fixquotas and i get this

Code:

Updating Quota Files......
quotacheck: Cannot stat() mounted device /dev/root: No such file or directory
quotacheck: Cannot find filesystem to check or filesystem not mounted with quota option.

also i tryed fixquotas forced but does not helped

also i checked if there was a folder
/dev/root
and there is a folder

but something is wrong some where but i don't get what!


i checked this topic but dosen't helped much!

i did everything on this topic but i still had this issue

quotacheck: Cannot stat() mounted device /dev/root: No such file or directory
quotacheck: Cannot find filesystem to check or filesystem not mounted with quota option.


sorry for being rude to you i'm mad cuz took me some hours to configure everything on whm and now i'm missing around with this

 

fixed by re installing os!
