Problème d'espace disque : /var/log plein

LoïsR

Bonjour à tous,

j'ai actuellement un problème d'espace sur ma partition système. Il semblerait que le problème vienne du dossier /var/log qui est plein :

lois@lois-300E4A-300E5A-300E7A-3430EA-3530EA:~$ sudo du -sh /var/log
[sudo] Mot de passe de lois : 
4,8G	/var/log

en regardant plus en détail dans le dossier j'obtiens ca :

Du coup je sais pas trop ce que je peux supprimer dans ce dossier pour libérer de la place sans créer de problèmes, je suis donc preneur de vos conseils !

merci d'avance,
Loïs.

Salut !

as-tu analysé le contenu de ces log ?

pour syslog, as-tu de la place pour le copier ailleurs avant raz ?

pour syslog qui est énorme :

sudo cp /dev/null /var/log/syslog

la commande remet à 0 le fichier sans toucher aux droits.

tu peux remplacer syslog par n'importe quel log.

les log avec 0, 1 sont des archives créées par logrotate, ils peuvent être supprimé.
par contre, il est bon d'y jeter un oeil avant de les poubeliser.

que donne

cat /etc/logrotate.conf

Salut,

5 Go de syslog, ce n'est en aucun cas normal (ça représente 5 fois le texte des 25 volumes de l'Encyclopédie Universalis !).
A mon avis, il faudrait effectivement le vider, puis redémarrer. S'il y a un problème, il recommencera à grandir, mais au moins il sera possible de l'ouvrir et de repérer le message indéfiniment répété avant qu'il soit gigantesque...

Avant suppression et justement à fins d'analyse, commmencer par sauvegarder un extrait de taille raisonnable :

cat /var/log/syslog | tail -n 150 > ~/syslog-tail-du-$(date +%Y%m%d-%Hh%M).txt

(Pas besoin d'être en root, c'est source de confusion).

moko138

LoïsR,
Quand on cherche les élément les plus volumineux, ls -l n'est pas le plus efficace (trop d'infos, et infos non ordonnées par taille).
Bien plus clair, préférer :

sudo du -x -d1 -BM /var/log 2>/dev/null | sort -nr | head -n7

qui indique, rangés par taille décroissante, le poids total et les 6 éléments les plus lourds
(L'option -BM : poids arrondi au Mio supérieur).

Par exemple :

sudo du -x -BM -d1 / 2>/dev/null | sort -nr | head -n7
3728M	/
2652M	/usr
430M	/lib
319M	/var
145M	/home
86M	/opt
64M	/boot

C'est tout de même plus lisible , non ? 🙂

/![/b] C'est le genre de commande à garder dans un mémo.
(L'option -x n'est pas utile dans /var/log, mais si on applique la même commande à "/" (par exemple), elle devient très utile).

LoïsR

Salut à tous !

merci beaucoup pour vos réponses. J'ai supprimé syslog et enregistré une bonne partie.
Le message d'erreur qui revient le plus souvent est :

Feb 14 19:28:55 lois-300E4A-300E5A-300E7A-3430EA-3530EA org.kde.kuiserver[1877]: "KConfigIni: In file /boot/initrd.img-4.4.0-62-generic, line 27087: " Invalid entry (missing '=')

ou encore :

Si quelqu'un peut m'aider à comprendre ce que ca veut dire ce serait super !

Merci pour la commande Moko138, elle est ajoutée à mon mémo 😉

Attention !
Si tu as supprimé syslog, tu dois
soit redémarrer,
soit plus simplement relancer :

sudo service rsyslog restart

Puisque le fichier /boot/initrd.img-*** est mal formé, on peut penser que l'espace manquait pendant la dernière mise à jour.
Donc que donnent

df -Ti | grep -Ev "devpts|none|proc|sys|tmpfs|udev"; echo; df -Th | grep -Ev "devpts|none|proc|sys|tmpfs|udev"

sudo update-initramfs -u -k all

suivi de

sudo update-grub

merci encore pour votre aide !

moko138

1) "unknown Linux distribution trouvé sur /dev/sda6"
Or sda6 c'est ton home. Il ne devrait pas être pris pour un système. À moins que...
N'aurais-tu pas installé par erreur un double de grub dans sda6 ? 🙂

2) En supposant que tu as redémarré depuis le sudo update-initramfs -u -k all, que donne

ls -sS1 /var/log | head -n 7

LoïsR

1) Ce n'est pas moi qui ait installé ubuntu sur ma machine, mais la personne qui s'en est chargé l'a peut être fait par erreur. Ou alors c'est une fausse manip de ma part mais je n'ai aucune idée de comment on installe un grub...

2)

Bonsoir
Peux-tu donner le retour des commandes

Tu pourras aussi libérer un peu de place

Un retour complet doit contenir toutes les lignes,
depuis celle, entière, de la commande
jusqu'à la ligne attendant la commande suivante, exemple :

moi@mon-pc~$: ma-commande
son retour
moi@mon-pc~$:

Faute de quoi, il manque souvent à ceux qui tentent de t'aider des éléments essentiels.

Donc merci de donner le retour, cette fois complet, de

sudo update-initramfs -u -k all

LoïsR

J'ignorais que la ligne attendant la commande suivante était importante... à part ça, les retours que j'ai postés comprennent toutes les lignes renvoyées par la commande.

Bonjour,

Peux-tu aussi donner le retour de

dmesg  |  tail  -100

Je mémorise une autre discussion qui semble avoir le même logiciel comme cause https://forum.ubuntu-fr.org/viewtopic.php?pid=21689032#p21689032

moko138

En attendant de trouver le remède, voici une ligne qui te libérera de l'espace :

cd /var/log; echo '' | sudo tee syslog.1; sudo rm syslog && sudo service rsyslog restart; cd

et qu'on peut relancer chaque fois que syslog ou syslog.1 ont enflé.

@Bougron : merci pour le lien, je vais lire cette discussion en détail dès que j'aurai un peu de temps
@moko138 : merci pour la commande !

Bougron

Bonsoir

Peux-tu redonner le résultat de cette commande car je ne vois rien très anormal dans la trace (je considère que le wifi c'est devenu un classique)

sudo du -x -d1 -BM /var/log 2>/dev/null | sort -nr | head -n7

sudo ls -ls /var/log

sudo ls -ls /tmp
