Question

我的MongoDB卡住并返回以下错误：

2019-01-28T18:28:53.419+0000 E STORAGE  [WTCheckpointThread] WiredTiger error (28) [1548700133:419188][1:0x7feecb0ae700], file:WiredTiger.wt, WT_SESSION.checkpoint: /data/db/WiredTiger.turtle.set: handle-open: open: No space left on device

但是，我的磁盘上有空间：

df -h

udev            992M     0  992M   0% /dev

这将是我的docker-compose：

version: "3"
services:

# MariaDB
    mariadb:
        container_name: mariadb
        image: mariadb
        ports: ['3306:3306']
        restart: always
        volumes:
            - /home/ubuntu/mysql:/var/lib/mysql
        environment:
            - "MYSQL_ROOT_PASSWORD=PasswordGoesHere"
        command:
            # - --memory=1536M
            - --wait_timeout=28800
            - --innodb_buffer_pool_size=1g
            - --innodb_buffer_pool_instances=4
            # - --innodb_buffer_pool_chunk_size=1073741824

# APACHE
    apache:
        container_name: apache
        image: apache-php7.1
        ports: ['80:80', '443:443']
        restart: always
        entrypoint: tail -f /dev/null
        volumes:
            - /home/ubuntu/apache2/apache-config:/etc/apache2/sites-available/
            - /home/ubuntu/apache2/www:/var/www/html/

# MONGODB
    mongodb:
        container_name: mongodb
        image: mongo
        ports: ['27017:27017']
        restart: always
        command:
            - --auth
        volumes:
            - /home/ubuntu/moongodb:/data/db

我的docker-compose.yml是否会出现问题？因为我使用的是物理磁盘而不是虚拟磁盘。我可以运行这些应用程序，并且1-2小时后，mongo会再次失败。

Answer 1

看起来100％的inode正在使用（来自protected void Page_Load(object sender, EventArgs e) { if(Session["UserType"].ToString() == "Admin") { btnSave.Visible = true; } else { btnSave.Visible = false; } }输出）。尝试寻找dangling volumes和cleaning them up。另外，最好确保docker daemon使用生产级存储驱动程序（about storage drivers，choosing a storage driver）。

Answer 2

如果您在centos / RHEL / Amazon Linux中运行此程序，则应该知道devicemapper在Docker中释放inode时存在重大问题。

即使您修剪了整个docker系统，它仍然会挂在许多inode上，真正解决此问题的唯一方法是基本上让docker内部崩溃：

service docker stop
rm -rf /var/lib/docker
service docker start

这应该释放您所有的inode。

我已经花了很多时间，Docker确实只完全支持Ubuntu overlay2，并且从技术上讲，不支持devicemapper。

Answer 3

清理 docker 缓存 - 卷和容器

对我来说它有效：

docker system prune

然后

docker volume prune

或在一行中：

docker system prune --volumes

要查看所有卷：docker volume ls

显示docker磁盘使用情况：docker system df

MongoDB的Docker设备上没有剩余空间
