k8s 记录下docker 存储空间不足导致问题
在虚拟机上启动kubelet ,journalctl -fu kubelet 疯狂打印间接打印Thin Pool has 2962 free data blocks which is less than minimum required 163840 free data blocks. Create more free space in thin pool or use dm.min_free_s
在虚拟机上启动kubelet ,journalctl -fu kubelet 疯狂打印
间隔打印
其中 error:
Thin Pool has 2962 free data blocks which is less than minimum required 163840 free data blocks. Create more free space in thin pool or use dm.min_free_space option to change behavior

Thin Pool Minimum Free Space = 10.74GB 而 Data Space Available = 723.8MB,这说明 Data Space Available 可用空间以低于 Thin Pool 所需最小空间,这会导致镜像无法正常启动。

docker system prune -a -f --volumes
另外:
data space used not matching docker images output
docker info 中 data space used (93.18G) 使用总和与 docker stystem df (617.3MB) 的使用情况不一致…

一怒之下只得卸了docker 重装(本地虚拟机学习…),磁盘空间回来了 - - 结合以上:可能是我修改过docker storage-driver 存储模式导致的?
[root@hadoop03 docker]# docker info
