Espace disque libre 1% Dossier var/mail

imacnicolas · Septembre 28, 2025, 5:35

Bonjour,

J’ai une box Luna depuis 1 an maintenant. Avant je faisais tourner jeedom sur un raspi mais à la fin avec le passage à zwavejs j’avais trop de plantage et des lenteurs. J’ai récupéré ma sauvegarde et je l’ai installé direct dans la Luna.

Depuis quelques jours je n’ai que des plantages, je remarque que l’espace libre est de 1%. J’ai lu beaucoup de sujets sur le forum qui mon bien aidé. J’ai réussi à passer à 4% …

J’ai fait la commande : sudo du -s /* | sort -rn

10858588	/var
2527236	/usr
524292	/swapfile
284124	/root
3828	/tmp
3374	/etc
1296	/run
16	/i18n
5	/home
0	/userdata
0	/sys
0	/srv
0	/sbin
0	/proc
0	/opt
0	/mnt
0	/media
0	/lost+found
0	/lib
0	/dev
0	/boot
0	/bin

en poursuivant dans /var :

7744080	/var/mail
1972976	/var/www
895368	/var/log
359922	/var/lib
77643	/var/cache
1976	/var/backups
64	/var/spool
36	/var/tmp
0	/var/run
0	/var/opt
0	/var/lock
0	/var/local

Je trouve le dossier mail énorme ! puis-je tout vider ? comment expliquer la taille pour éviter que ça grossisse encore ?
si je peux tout vider peut-on me donner la ligne de commande à taper afin que je ne fasse pas de bêtise svp

Je pourrais ouvrir un ticket d’assistance, mais j’aime bien essayer de comprendre/ apprendre.
En vous remerciant pour votre aide
Nicolas

Salut

Je commencerai par voir ce qu’il y a dans ces mails.

Que donne la commande suivante qui va lister les 500 dernières lignes des fichiers présents dans ce répertoire ?

sudo tail -500 /var/mail/*

Bonjour

J’ai remarqué que certains plugins utilisaient des dépendances qui généraient des mails. Pour moi le plugin apcups qui a généré plus de 4000 mails. Pour les lire et effacer ces mails je conseille de lire le man mail. Je suis sur une Vm en Proxmox, avec de la place disque donc pas d’incidence sur le fonctionnement.

imacnicolas · Septembre 28, 2025, 7:21

la commande ne fonctionne pas, j’ai la réponse suivante:

tail: option used in invalid context -- 5

en continuant dans le /mail j’arrive ici

root@JeedomLuna:~# sudo du -s /var/mail/* | sort -rn
7744016	/var/mail/mail
60	/var/mail/www-data

comment faire pour voir la suite des mails ?

Aurel · Septembre 28, 2025, 7:44

Dans ce cas fait

sudo tail -500 /var/mail/mail

JeedomLuna : Sep 27 21:27:13 : www-data : problem with defaults entries ; PWD=/var/www ; USER=root ;

Pour la ligne :

unable to resolve host JeedomLuna: Name or service not known

j’ai résolu le problème hier en éditant le fichier /etc/hosts.
Cela avait-il un rapport avec mon remplissage de memoire ??!

Ben la tu avais des alertes en boucle toutes les 5 minutes pour pas grand chose.
Pour moi tu peux tout virer.

Mais c’est curieux quand même d’avoir ces soucis avec une luna, tu as refait une install recemment ?

imacnicolas · Septembre 28, 2025, 8:48

Non aucune installation récemment !
J’ai eu le problème du hostname dès que j’ai installé mon backup du rasp-pi sur la luna. Je n’avais pas eu le temps de regarder la correction.

Tu peux me dire exactement la ligne de code a rentrer pour effacer les messages dans mail ?

(Je ne suis pas un pro du ssh)

Aurel · Septembre 28, 2025, 9:17

Si tu veux tout effacer d’un bloc tu peux virer directement le fichier.
Au prochain mail reçu ce dernier sera recréé

Dans ton cas :

sudo rm -f /var/mail/mail

Et revérifie ton espace disque après

imacnicolas · Septembre 29, 2025, 7:22

Super j’ai vidé le dossier mail maintenant j’ai ça :

1989404	/var/www
898396	/var/log
327326	/var/lib
77651	/var/cache
1976	/var/backups
64	/var/spool
64	/var/mail
36	/var/tmp
0	/var/run
0	/var/opt
0	/var/lock
0	/var/local

l’espace libre disque est repassé à 61%
Je vais surveiller dans le temps si le dossier mail se rempli rapidement
Merci beaucoup pour ton aide !!
