Il faut vérifier sur chaque noeud que les device pointent bien sur les mêmes disques en visualisant le fichier /var/lib/multipath/bindings
cat /var/lib/multipath/bindings # Multipath bindings, Version : 1.0 # NOTE: this file is automatically maintained by the multipath program. # You should not need to edit this file in normal circumstances. # # Format: # alias wwid # mpath0 3600508b300941040381c08a7e63b0054 mpath1 3600508b300941040bd935fb5a4f50055 mpath2 3600508b300941040955b14c205720056 mpath3 3600508b30094104074f74ee2e13f0057
Le cas échéant le supprimer et relancer le demon multipathd
Par défaut le démon multipathd n'est pas actif
chkconfig multipathd on
Sur chaque noeud installer ricci et le démarrer
