mod_ctlextra, export2odbc problem

Hi all,

When I try to export my Mnesia db to sql scripts, I get this :

# pwd
/var/lib/ejabberd/ebin
#
# du /etc/ejabberd/Mnesia.ejabbered@pr01-c30900-db03
4.4M /etc/ejabberd/Mnesia.ejabbered@pr01-c30900-db03
#
# ./ejabberdctl ejabbered@pr01-c30900-db03 export2odbc pr01-c30900-db03.mydomain.com /tmp/test2

Trying to export Mnesia table 'last' on server 'mydomain.com' to file '/tmp/test2/last.txt'
Trying to export Mnesia table 'offline' on server 'mydomain.com' to file '/tmp/test2/offline.txt'
Trying to export Mnesia table 'passwd' on server 'mydomain.com' to file '/tmp/test2/passwd.txt'
Trying to export Mnesia table 'private_storage' on server 'mydomain.com' to file '/tmp/test2/private_storage.txt'
Trying to export Mnesia table 'roster' on server 'mydomain.com' to file '/tmp/test2/roster.txt'
Trying to export Mnesia table 'vcard' on server 'mydomain.com' to file '/tmp/test2/vcard.txt'
Trying to export Mnesia table 'vcard_search' on server 'mydomain.com' to file '/tmp/test2/vcard_search.txt'
#
#
# du /tmp/test2/*

4.0K /tmp/test2/last.txt
4.0K /tmp/test2/offline.txt
4.0K /tmp/test2/passwd.txt
4.0K /tmp/test2/roster.txt
4.0K /tmp/test2/vcard_search.txt
4.0K /tmp/test2/vcard.txt

-> Nothing into files (just begin;commit;).

My Mnesia db get about 700 users, so it's not really empty :p
if I wrote someting stupid at the "server" arg place, I get the same result, so, how can I make me sure that I try to export the right db ???

Another information, I'm pretty sure on the args I submit because this works :

# ./ejabberdctl ejabbered@pr01-c30900-db03 vcard-get toto1 mydomain.com N GIVEN
toto

Is someone can help me ?
Is someone have face the same problem ? This stuff make me crazy !
