Bonjour,
J'ai un problème pour faire une copie simple de fichiers (cp hosts
hosts.txt) au sein d'un partage SMB (monté par autofs). ça m'indique
"Processus arrêté", puis après un nouvel essai ça reste bloqué/freezé,
je n'ai plus la main sur la console (ctl+C, D, Z n'ont aucune action).
Quand je créé un fichier, pas de souci, quand j'édite un fichier pas de
souci, le seul problème est de copier. La suppression ni le
renommage/déplacement n'est problématique. le processus est indiqué
ainsi : xxx 25304 24752 0 21:35 pts/2 00:00:00 cp hosts hosts.txt le
kill du processus ne fonctionne pas. Les droits sur les fichiers :
-rwxr-xr-x 1 xxx yyy 0 31 janv. 21:34 hosts.txt -rwxr-xr-x 1 xxx yyy 0
28 janv. 18:13 hosts voici les droits du montage : ├─/mnt/xxx

Dans syslog, j'obtiens des erreurs au niveau du kernel.

Si vous avez une piste, ça m'arrangerait de pouvoir faire des
copies/synchronisations de fichiers sur le service de fichier monté.
Merci !
