rsync open openat : différences Debian 10 Debian 9

Bonjour,
Impossible de faire un rsync en Debian 10 alors que le même script fonctionne en Debian 9

La commande rsync est lancée par un cron qui lance un script perl et lance la commande suivante :

rsync -vrltH --delete --progress --numeric-ids --stats -pgo -D --exclude-from=/san/pcdsi/L105140/20210323163539/exclude --link-dest=/san/pcdsi/L105140/202102100956/tree "/mnt/pc-backup/L105140/Users/"/ /san/pcdsi/L105140/20210323163539/tree

Voilà ce que je constate en Debian 10 :

strace -o toto /usr/bin/perl /usr/sbin/dirvish --vault L105140
dirvish L105140:default error (23) -- partial transfer
expr: syntax error: unexpected argument '0'
expr: non-integer argument
dirvish error: branch /san/pcdsi/L105140:default image 20210324090006 failed

et
rsync: change_dir "/etc/dirvish//"/mnt/pc-backup/L105140/Users/"" failed: No such file or directory (2)
rsync error: some files/attrs were not transferred (see previous errors) (code 23) at main.c(1207) [sender=3.1.3]

Bien sûr sur tous les serveurs en Debian 9 c'est ok

Si je lance la commande rsync ci-dessus en Debain 10 en root tout fonctionne !!!!!

Dans les trace je vois :

read(8, "rsync: change_dir \"/root//\"/mnt/"..., 8192) = 8192

le change_dir n'apparait pas en Debian 9

il semblerait que les open de fichiers soient différents :

Citation:

---

L'appel système openat() opère de la même manière que open(2), excepté pour les différences décrites dans cette page de manuel.

Si le chemin fourni dans pathname est relatif, il est interprété par rapport au répertoire référencé par le descripteur de fichier dirfd (plutôt que par rapport au répertoire de travail courant du processus appelant, comme cela est fait par open(2) pour un chemin relatif).

Si pathname est relatif et si dirfd est la valeur spéciale AT_FDCWD, pathname est interprété par rapport au répertoire de travail courant du processus appelant (comme avec open(2)).

Si pathname est absolu, dirfd est ignoré.

Avez-vous une idée ?

je suis complétement bloqué pour l'installation des nouveaux serveurs. Thanks

Est-ce que quelqu'un qui connait Perl peut me dire où est lancé le rsync dans le code ci-dessous de dirvish ? J'ai tout regardé je ne saisis pas ! Je voudrais modifié ce code mais je ne comprends à quelle moment le rsync est lancé ?
Merci

Bonsoir;
le code dans le script dirvish.pl pour le lancement du rsync est $return = system($rcmd);.
Je vais donc envoyer cette commande dans un fichier et mettre en place une tempo.
Pendant ce temps un cron lancera le rsync en question.
Si vous avez des exemples pour faire cela :
- dans un script perl (dirvish.pl) écrire un fichier horodaté
- le script perl doit attendre la fin de l’exécution du contenu du fichier horodaté (lancé par le cron)

Merci à vous

Bonjour,
dans ce srcipt perl une fois écrite le commande rsync dans un fichier

Code:

---

1 2 3 4 5 6 7 8 9

printf SUMMARY "\n%s\n", 'Commande rsync ecrite dans fichier : '; my @tmp; push @tmp, @cmd; foreach my $v (@tmp) { printf SUMMARY "%s ", $v; } #print @tmp; open (FICHRSYNC, ">$fich_rsync"); print FICHRSYNC "@tmp " ;

---

, je dois l'exécuter dans un cron
ma question :
- comment attendre dans le fichier perl que la commande rsync du cron soit finie
- il me faut le code retour du rsync du cron que je dois remettre dans le script perl à $status{code} =

merci à vous
