Thanks for your answer !

I check in my ndb_1_cluster.log and i have this line :
2012-10-04 18:10:39 [MgmtSrvr] WARNING  -- Failed to allocate nodeid for 
API at 2.2.2.2. Returned eror: 'No free node id found for mysqld(API).'
2012-10-04 18:10:42 [MgmtSrvr] WARNING  -- Failed to allocate nodeid for 
API at 2.2.2.2. Returned eror: 'No free node id found for mysqld(API).'


But when i run on my manager ndb_mgm -e show i have this :

ndb_mgm> show
Connected to Management Server at: localhost:1186
