mysql ne démarre plus à l'activation du cluster

Bonjour,

J'ai installé mysql cluster sur 3 nœuds: 2 nœuds data et 1 nœud SQL et Management en même temps.
Le service mysql démarre sans problème sur les 3 noeuds quand le cluster n'est pas actif c'est à dire quand je commente les lignes suivantes de mysqld.cnf:

# Run ndb storage engine
#ndbcluster
# IP address management node
#ndb-connectstring=10.25.160.53

[mysql_cluster]
# IP address management node
#ndb-connectstring=10.25.160.53

Dans les log de mysql, je trouve les lignes suivantes:

Re : mysql ne démarre plus à l'activation du cluster

J'ajoute que les noeuds sont bien reconnus au niveau du management du cluster comme suite:

id=2 (not connected, accepting connect from 10.25.160.51)
id=3    @10.25.160.52  (mysql-5.6.31 ndb-7.4.12, starting, Nodegroup: 0)

[ndb_mgmd(MGM)] 1 node(s)
id=1    @10.25.160.53  (mysql-5.6.31 ndb-7.4.12)
