Hi
Thanks for your help i solve the problem by replacing this line
location cli-standby-nfs nfs \
rule $id="cli-standby-rule-nfs" -inf: #uname eq
storage02.myriapulse.local
by
location ms_drbd_nfs-master-storage01.myriapulse.local ms_drbd_nfs rule
role=master 100: \#uname storage01.myriapulse.local
but i have an other problem because i have 2 network card
Eth1: replication link
-------------- ----------------
| Server 1 |------| Server 2 |
-------------- ----------------
| |
Eth0 eth0
| |
External Network
The data of the nfs server is accessed via eth0, but if y shutdown eth0 on
the node witch is running the resource, the resource doesn't migrate and is
unreachable, i think it's because of the replication link (who stay up)

You really should get your line breaks right!

DRBD is promoted just fine.
The resources using it are not.
Which is expected:
As long as you explicitly forbid "nfs" to run on storage02,
you should not complain about nfs not being started on storage02.
Hint:

storage02.myriapulse.local
