清理
极狐GitLab 提供 Rake 任务以清理极狐GitLab 实例。
移除未引用的 LFS 文件
引入于极狐GitLab 12.10。
当您从仓库历史移除 LFS 文件,它们会变成孤立文件,继续消耗磁盘空间。 通过这个 Rake 任务,您可以从数据库移除不活跃的引用,从而允许 LFS 文件的垃圾回收。
例如:
# omnibus-gitlab
sudo gitlab-rake gitlab:cleanup:orphan_lfs_file_references PROJECT_PATH="gitlab-org/gitlab-foss"
# installation from source
bundle exec rake gitlab:cleanup:orphan_lfs_file_references RAILS_ENV=production PROJECT_PATH="gitlab-org/gitlab-foss"
您也可以使用 PROJECT_ID
而不是 PROJECT_PATH
来指定项目。
例如:
$ sudo gitlab-rake gitlab:cleanup:orphan_lfs_file_references PROJECT_PATH="gitlab-org/gitlab-foss"
I, [2019-12-13T16:35:31.764962 #82356] INFO -- : Looking for orphan LFS files for project GitLab Org / GitLab Foss
I, [2019-12-13T16:35:31.923659 #82356] INFO -- : Removed invalid references: 12
默认情况下,这个任务不会删除任何东西,只会展示它能够删除的文件引用的数量。如果您想删除引用,请使用 DRY_RUN=false
运行命令。
您也可以使用 LIMIT={number}
参数限制删除的引用的数量。
请注意,这个 Rake 仅将引用移除到 LFS 文件。未引用的 LFS 文件稍后将进行垃圾回收(一天一次)。
如果您需要立即进行,请运行 rake gitlab:cleanup:orphan_lfs_files
。
立即移除未引用的 LFS 文件
引入于极狐GitLab 12.10。
未引用的 LFS 文件会被每天移除一次,您也可以立即移除。例如:
# omnibus-gitlab
sudo gitlab-rake gitlab:cleanup:orphan_lfs_files
# installation from source
bundle exec rake gitlab:cleanup:orphan_lfs_files
示例输出:
$ sudo gitlab-rake gitlab:cleanup:orphan_lfs_files
I, [2020-01-08T20:51:17.148765 #43765] INFO -- : Removed unreferenced LFS files: 12
清理项目上传文件
清理不在极狐GitLab 数据库中的项目上传文件。
从文件系统清理项目上传文件
引入于极狐GitLab 11.2。
您可以清理不在极狐GitLab 数据库中的本地项目上传文件。 如果无法找到其项目,任务会试图修复文件,否则它会将文件移动到 lost+found 目录中。
# omnibus-gitlab
sudo gitlab-rake gitlab:cleanup:project_uploads
# installation from source
bundle exec rake gitlab:cleanup:project_uploads RAILS_ENV=production
示例输出:
$ sudo gitlab-rake gitlab:cleanup:project_uploads

移除 Orphan 产物文件
引入于极狐GitLab 12.1。
ionice
支持修复于极狐GitLab 12.10。
当您发现磁盘上有多余的作业产物文件和/或目录,您可以运行:
sudo gitlab-rake gitlab:cleanup:orphan_job_artifact_files
这个命令:
- 扫描整个产物文件夹。
- 检查哪个文件在数据库中还有记录。
- 如果没有发现数据库记录,文件和目录会从磁盘中删除。
默认情况下,这个任务不会删除任何内容,仅展示它可以删除的内容。
如果您想删除文件,您可以使用 DRY_RUN=false
运行命令:
sudo gitlab-rake gitlab:cleanup:orphan_job_artifact_files DRY_RUN=false
您可以使用 LIMIT
(默认为 100
)限制删除的文件的数量:
sudo gitlab-rake gitlab:cleanup:orphan_job_artifact_files LIMIT=100
如果运行上面的命令,则最多会从磁盘删除 100 个文件。您可以使用它删除少量文件,用作测试。
假设 DEBUG=1
展示每个被检测为孤立文件的文件的完整路径。
如果安装了 ionice
,任务使用它确保命令不会在磁盘上引发太多负载。您可以使用 NICENESS
配置优先级别。
以下是有效级别,您也可以使用 man 1 ionice
进行确定。
