Run it again and say Yes. Your data won’t be touched, only old docker images will be removed.

Thanks. I did that but it does not seem working. Please see this snapshot. Sorry I forgot to attach this earlier. Thanks in advance

use either du -sh * and drill down into the large directories or ncdu if you have that package available, and try to figure out where exactly your space has gone

if it is user content you will probably have to increase diskspace on your server, but a common problem on servers that run docker for a while is that the default json logging engine never rotates the logs

[root@discocent discourse]# cd /var/lib/docker/containers/
[root@discocent containers]# du -sh *
5.1M	86981cd18ab1d8e95e502bf08a1fdc949030cddc29079b53a8e17b2c6a98ba6f

[root@discocent 86981cd18ab1d8e95e502bf08a1fdc949030cddc29079b53a8e17b2c6a98ba6f]# ls -lh

that’s 5M of log for my idle test instance after a couple days, an active server will be larger. if you run other containers they might be logging even more.

You can configure docker to handle log rotation, check out Configure logging drivers | Docker Documentation …not sure why it’s not the default.

Hi @ssvenn

Many thanks. this is much appreciated. I have run the commands and i can see the following statistics. Would you mind to advise, how does this look like as I am unable to interpret I am afraid. Thanks in advance.

I have been surprised to see the occupied space. As we have very minimal activty on our forum. Thanks

ok, that’s not your problem then. Only one container and only 0.5MB of logs.

if you run du -sh * again in the / top directory maybe you will get a better picture of where the space has gone. I highly recommend ncdu to make it easier ( NCurses Disk Usage )

on my test instance docker uses about 8GB on images, check out Prune unused Docker objects | Docker Documentation for help on how to clean that up.

docker image prune -a usually frees up a lot of space for me, you might have to docker rm app to delete your old Discourse app container first. If you have lots of forum backups maybe you could download them to your local machine to free up some additional space.

another thing you should check is docker ps -a to see if you have any unexpected containers. Sometimes a failed rebuild will leave a dangling container that you have to remove manually.

[root@discocent /]# docker ps -a

Have you checked your backups? It’s quite easy for them to fill your disk.

嘿 @pfaffman 关于这个有个快速问题。我遇到了同样的问题，所以我运行了 du -sh *。没有文件超过 1MB。

所以我没有删除。

但我尝试了 docker image “prune -a”，回收空间：0B。

还有什么我应该做的吗？我的问题与我最近的升级有关，该升级导致应用程序关闭。

你检查过 /var/discourse/shared/standalone/backups/default 吗？这很可能是罪魁祸首。

我正在 https://www.pfaffmanager.com/ 开发一款新产品。如果你登录那里，点击顶部的“服务器列表”按钮，然后点击“免费！管理现有服务器”按钮，并按照（我希望）它建议的那样为你的服务器配置它，我会为你弄清楚。

谢谢，是的，我检查了备份。总共 5 个文件 * 16M。这很小，对吧？

我也运行了这个

我现在正在尝试你的新产品建议。

哦。你只有 12G。这不够。我建议至少 25G，最好是 50G。

好的，明白了。几分钟前，我将音量增加了 30，可能还在优化中

顺便说一句，我对您的产品的用户界面感到困惑，但也突然对您将如何从中调试感到好奇。哈哈哈。我将通过私信与您联系，以避免在此违反任何规则。
