处理 K8S Orphaned pod found - but volume paths are still present on disk 孤儿pod

问题概述

查看kubelet或/var/log/messages日志一直包错，发现是孤儿pod，是由于其pod被删除后存储路径还保存在磁盘。

报错如下

[root@node5 ~]# journalctl -fu kubelet

解决办法

解决思路

根据/var/log/messages或kubelet报错，查找孤儿pod
通过mount命令查找孤儿pod的挂载
卸载孤儿pod的存储挂载
删除/var/lib/kubelet/pods下孤儿pod的存储路径

使用脚本处理，脚本内容如下

#!/bin/sh

orphanedPods=`cat /var/log/messages|grep 'orphaned pod'|awk -F '"' '{print $2}'|uniq`;

orphanedPodsNum=`echo $orphanedPods|awk -F ' ' '{print NF}'`;

echo -e "orphanedPods: $orphanedPodsNum \n$orphanedPods";

for i in $orphanedPods

do

echo "Deleting Orphaned pod id: $i";

rm -rf /var/lib/kubelet/pods/$i;

done

在报错的节点直接执行脚本即可
