Bonjour,
Je rencontre un problème étrange sur une machine qui lance des scripts
de montages samba planifiés, en vue de faire des sauvegardes.
Au moment du lancement du montage j'obtiens l'erreur suivante:
Can't get /etc/mtab~ lock filesmbmnt failed: 1
Cette erreur n'est pas systématique, j'ai également d'autres scripts qui
tournent et qui ne posent pas de problème... ce n'est pas non plus un
problème dans mon script car cette erreur n'apparaît pas à chaque fois.
Cela ne semble pas non plus dû à la machine dont le partage est monté:
l'erreur survient avec différents serveurs, aléatoirement.
Google n'a pas pu m'aider. Si quelqu'un à une idée de l'origine du
problème, je suis preneur ...
voici mon script (dsl si c'est pas très lisible ... je le mets en PJ
également) :
#!/bin/sh
# Machine ou se connecter
HOST='djerba'
# Repertoire partage de la machine
SHARE='E'
# Destination des points de montages

# Device (dd externe) destination a monter/demonter
DEVICE_DEST='/media/Bck_Quot_2'
