/addons目录无法访问

李丑男

前面碰到一次系统无法启动的问题，后来查看是因为8g的卡满了，无法写入。把内存卡插到电脑上查看，发现home-assistant_v2.db文件有2G多，删掉之后就可以正常启动了。
但是还发现有一个文件占了有2G多，好像是在/addons目录下面。
但是现在ssh到HA上面，查看/addons目录是空的。然后也找不到大文件到底在哪里。有谁知道呢。

core-ssh:/addons# df -h

解决：使用数据库客户端，连接到树莓派上去，把homeassistant这个库完全删掉，马上就正常了，释放了3G的空间出来。

addons里面有个data目录是存容器的持久化数据的，这个要看你装了什么addons ，如果是装了mariadb 他也一样会写入到这个文件夹中，导致文件越来越大。这个你需要看看你装了什么addons来判定了

我确实有装了mariadb ，怎么进去这个目录呢？我知道把卡挂载到其他linux下面是可以看到，在HA里面怎么看不到下面的文件。

core-ssh:~# cd /addons/
core-ssh:/addons# ls
core-ssh:/addons# ls -la
