Debugging Common Problems With Using MogileFS

Unable to store files

  1. Does the user mogstored is running as have permission to write to files on var/mogdata/devN * ?
  2. Does that user own the /var/mogdata/devN directory?
  3. Is there at least min_free_space free on the device? (Default: 100MB)
  4. Are all machines using accurate time? In particular, trackers and databases should have time that's in sync, otherwise devices will not be considered writable because the device report from the monitor in the database (which uses the database's time), will be older than tracker's localtime - max_disk_age .

yum命令的形式一般为：yum [options] [command] [package ...]，其中[options]是可选的，[command]为所要进行的操作，[package ...]是操作的对象[^1]。 ### 选项说明 - `-h`：提供帮助信息。 - `-y`：在安装过程提示选择时全部回答"yes"；在使用基本语法时，对所有提问都回答"Yes" [^1][^3]。 - `-q`：不显示安装的过程 [^1]。 ### 常用命令及功能 - `install`：安装RPM软件包 [^3]。 - `update`：更新RPM软件包 [^3]。 - `check-update`：检查是否有可用的更新RPM软件包 [^3]。 - `remove`：删除指定的RPM软件包 [^3]。 - `list`：显示软件包信息 [^3]。 - `clean`：清理yum过期的缓存 [^3]。 - `deplist`：显示yum软件包的所有依赖关系 [^3]。 - `yumdownloader <package-name> --resolve --enablerepo=[repo]`：下载rpm包，`--resolve`表示依赖包也会被下载，`--enablerepo=<repository>`可指定yum源，若不知可以省去此参数 [^5]。 ### 编辑配置文件 yum的一切信息都存储在`/etc/yum.repos.d`目录下的配置文件中。若要创建新的yum仓库配置文件，可在`/etc/yum.repos.d/local.repo`文件中添加本地仓库信息，包括仓库的ID、名称、基础URL（指向rpm包目录）以及是否启用GPG检查等 [^2][^4]。 ### 安装yum及其依赖 当需要从本地仓库安装yum包，若yum尚未安装或配置不正确，可使用rpm命令直接安装rpm包：`rpm -ivh /opt/yum-rpms/*.rpm --nodeps --force` [^2]。 ### 编辑相关配置文件 编辑`/etc/yum/pluginconf.d/fastestmirror.conf`文件示例如下： ```plaintext [main] enabled=1 verbose=0 always_print_best_host = true socket_timeout=3 ```
