MongoDB的Docker设备上没有剩余空间 [英] MongoDB no space left on device with docker

问题描述

我的MongoDB卡住并返回以下错误:

My MongoDB gets stuck and returning the following error:

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:

However, my disk has space:

df -h

udev            992M     0  992M   0% /dev

这将是我的docker-compose:

And this would be my 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.

Would it be a problem with my docker-compose.yml? Because I'm using the physical disk and not virtual. I can run the applications and after 1-2 hours the mongo will fail again.

推荐答案

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.

If you are running this in centos/RHEL/Amazon Linux you should know that the devicemapper has major issues with releasing inodes in Docker.

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内爆:

Even if you prune the entire docker system, it will still hang on to a lot of inodes, the only way to really solve this is to basically implode docker:

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

这应该释放所有的inode.

This should release all your inodes.

我已经花了很多时间，Docker确实只完全支持Ubuntu overlay2，并且在技术上不支持devicemapper.

I've spent a lot of time on this, Docker really only fully supports Ubuntu overlay2, and the devicemapper, although works, is technically not supported.
