Ubuntu 18.04の/ var / logに保存された巨大なsyslog、syslog.1、kern.logファイル

私は最近PC（Nvidia GeForce GTX 1080 Ti GPU搭載）でUbuntu 16.04を18.04にアップグレードしました。それ以来、ファイルシステムがこれらの巨大なログファイルから構築されています。コンピュータをシャットダウンするたびに、PCがシャットダウンするまで、無限の数のpcieportメッセージが表示されます。

昨日、マシンを一晩置いたままにしましたが、戻ってきたときに、ディスク領域がすべて使用されているという通知がありました。つまり、_/dev/sda1_は100％使用されていました。私はdu- commandを介してこれを見つけることができ、_/var/log/_フォルダー内のログファイルに問題を特定しました。これには、_350GB_を超えるログファイルが含まれています。

現在、ログファイルは再構築されており、現在は約_150GB_の領域を占めています。問題の原因となっているログファイルは、_syslog.1, syslog_および_kern.log_です。

私の質問は：この問題の原因と修正方法は？

システムとログファイルの数行に関する情報を以下に示します。私はそれらを再び削除しますが、それらを際限なく削除することは最良の長期的な解決策ではないようです。

私はここの手順を使用してすでに問題を解決していると思います：

https://bugs.launchpad.net/ubuntu/+source/linux/+bug/152117

対応策：カーネルコマンドラインにpci = noaerを追加します。

（1）/ etc/default/grubを編集して、GRUB_CMDLINE_LINUX_DEFAULTで始まる行にpci = noaerを追加します。次のようになります。

GRUB_CMDLINE_LINUX_DEFAULT = "静かなスプラッシュpci = noaer"

（2）「Sudo update-grub」を実行します

（3）再起動

これらの手順を実装した後、システムをシャットダウンした後、pcieport- messagesが表示されなくなり、ログファイルのサイズが大幅に増大しなくなりました。

ただし、これによりエラーメッセージの根本的な原因が修正されたかどうかはわかりません...
