I found the root of the trouble
to better understand I'll write a
"short history"01. server 1 - old hardware (P3/600 256MRAM 32G/UDMA66 -
not important)
02. server 2 - new hardware (P4D/2.4 2GRAM 320G/SATA2 -
also not important)
03. using this
great cotrib
http://wiki.contribs.org/Moving_SME_to_new_Hardware I moved everything to the new hardware (or almost all)
04. starting from this moment I found that difference between quota repported by
quota and counted files using
du command
du /home/e-smith/files/users/username
- using
find command I verified all files used by the user with the problem (in my case was the UID 5053)
find / -user 5053 > /tmp/repportfile
by parsing this file (
repportfile) I found that this user has files in
/var/affa and several other places
in this moment you need to analyze all places and delete that ones which is not more needed
it could also happen that the "name" of the UID is changed between the moment of backup and the moment you try to find files - because of this is better to look after UID not after name
for example:
you make backup
delete user with name userxa and UID 5050
after some while create another user with name userxb and the server allocate the same UID 5050
the quota difference is reported!
if you'll look after name ( as I deed) you're lost
hope this will help somebody to don't wait or try to solve the trouble from the root
