Donc si je comprends bien il s'agit du var/log qui prends pas mal de place ??

Et voici les fichiers présent dans le dossier var/log :

cores                  dmesg.2.xz             dpkg_upgrade.log       messages               nginx                  smart_quick_log        synopkg.log
cstn                   dmesg.3.xz             httpd                  messages.0.gz          partition              ssupgradeerr.log       synosys.log
disk_overview.xml      dmesg.4.xz             httpd-error-user.log   messages.1.gz          php-fpm.log            surveillance.log       synoupdate.log
dmesg                  dms.log                log.nmbd               messages.2.gz          postgresql.log         surveillance.log.0.gz  syslog.log
dmesg.1.xz             dpkg.log               log.smbd               messages.3.gz          scemd.log              synolog                upstart

Il s'agissais du fichier httpd-error-user.log, que j'ai supprimé.

Il est en place depuis quelques temps suite à l'installation d'un site web

Bonjour meme soucis impossible de mettre mon synology à jour es ce que je crée un nouveau topic ou alors je mets ma configuration ici ?

merci
