[crazyaboutlinux]

we are receiving notification since 1st march 2011 regarding "Drive Space Warning on xxxxxxx" Drive Warning: /dev/sdb1
(/backup) is 85% full

but when we checking in whm it shows 69% Percent Used

See the latest current disk space usage

Device      Size   Used  Available Percent Used Mount Point
/dev/sdb1 230G 150G    69G               69%      /backup

any suggestion ?

Most likely the 85% was sent out when cPanel was doing it's actual backups, and you're just now seeing it. This happens from time to time, as cPanel handles backups quite ineptly, and you'll see this quite often.
