根因分析

overlay2 文件系统的 inode 或块配额已耗尽，通常是由于过多的容器层或悬空镜像占用了所有可用空间。

English

The overlay2 filesystem has exhausted its inode or block quota, typically due to excessive container layers or dangling images consuming all available space.

解决方案

  1. Run 'docker system prune --all --volumes' to remove unused containers, networks, images, and volumes. Then verify with 'df -h /var/lib/docker' and 'df -i /var/lib/docker'.
  2. Increase the overlay2 storage quota by editing /etc/docker/daemon.json: add '{"storage-opts": ["overlay2.size=100G"]}' and restart Docker. Note: this works only with xfs filesystem and project quotas enabled.

无效尝试

常见但无效的做法:

  1. 40% 失败

    Running 'docker system prune -a' without checking for running containers can remove essential images and containers, causing data loss.

  2. 60% 失败

    Increasing overlay2 size via daemon.json 'storage-opts' often fails because the underlying filesystem (e.g., ext4) does not support per-directory quotas.

  3. 70% 失败

    Rebooting the host only temporarily frees space if the root cause (e.g., log rotation) is not addressed.
