🧭 问题本质

JetBrains Gateway 在连接远程服务器时，会自动在远程机器的 /root/.cache/JetBrains 和 /root/.config/JetBrains 下安装一个远程 worker，用于运行 IntelliJ 的后台逻辑。

但现在磁盘或配额满了，所以部署失败。

查看磁盘使用情况

bash 复制代码

df -h

关键是这一行：

bash 复制代码

overlay 1.8T 1.8T 0 100% /

👉 根目录 / 已经被完全占满（Avail=0），这就是 JetBrains 报错的根源。

而且：

bash 复制代码

/dev/sdb1 15T 3.6T 11T 26% /workspace

👉 /workspace 挂载在另一个磁盘上，有 11T 可用空间。这很好，我们可以把 JetBrains 的缓存、配置目录迁移到这里。

我们让 JetBrains 的缓存目录放在 /workspace 下，而不是 /root。

执行以下命令一步步来 👇

1️⃣ 创建新的缓存和配置路径

bash 复制代码

mkdir -p /workspace/jetbrains_cache /workspace/jetbrains_config /workspace/jetbrains_remote_ide
chmod -R 777 /workspace/jetbrains_cache /workspace/jetbrains_config /workspace/jetbrains_remote_ide

2️⃣ 设置环境变量

bash 复制代码

# 2. 创建全局环境变量配置文件（JetBrains Gateway 会读取）
cat << 'EOF' > /etc/profile.d/jetbrains_env.sh
export XDG_CACHE_HOME=/workspace/jetbrains_cache
export XDG_CONFIG_HOME=/workspace/jetbrains_config
export JETBRAINS_REMOTE_DEV_DIR=/workspace/jetbrains_remote_ide
EOF

然后让配置立即生效：

bash 复制代码

# 3. 让环境变量立即生效
source /etc/profile.d/jetbrains_env.sh

3️⃣ 验证是否设置成功

执行：

bash 复制代码

# 4. 检查确认
echo $XDG_CACHE_HOME
echo $JETBRAINS_REMOTE_DEV_DIR

应输出：

bash 复制代码

/workspace/jetbrains_cache
/workspace/jetbrains_remote_ide

4️⃣ 清理 /root 缓存（可选但建议执行）

释放一些空间，防止别的程序出错：

bash 复制代码

rm -rf /root/.cache/* rm -rf /root/.config/* rm -rf /tmp/*

5️⃣ 重新打开 JetBrains Gateway 连接

这时 Gateway 会检测到新的缓存路径（在 /workspace 下），

磁盘空间足够，它会成功启动远程 IDE。
