Bonjour,
J'ai un problème pas commun ...
Soit un cluster (qui tourne depuis 6 mois) avec une tete de cluster
nommee head. Après chaque calcul, les noeuds font un scp des fichiers de
resultats.
Dans mon cas le scp head -> noeud fonctionne mais scp noeud -> head
plante et ce bien que l'authentification réussisse (voir logs).
Avez vous une idee de pourquoi head n'accepte plus les fichiers par scp.
tous les problemes ont commence quand le disque dur d'un noeud a
plante, hier mais je ne vois pas le rapport.
Merci de votre aide. A++
Voici les logs :
