Bonjour,
je débarque sur un problème il ya 4 jours, en fait je suis entrain de mettre en place un cluster
avec 2 noeuds un primaire et un secondaire.
voici l'architecture et les conf :
2 IBM servers with RAID 1
drbd version: 8.2.6 (API: 88/proto :86-88) and heartbeat installed on 2 servers

donc, lorsque je redémarre heartbeat sur le noeud primaire le noeud secondaire prend la main
et monte la partition /data et devient primaire -----> comportement correct
mais le sousci, losque je débranche le noeud primaire-----> blocage du cluster et voila le log sur
le noeud secondaire:

Note: lorsque je remet le cable réseau du noeud primaire le cluster se débloque et monte sur le primaire.
Merci beaucoup en avance.
