问题描述
在按照官方文档升级路线11.0.2=>17.2.2的过程中,升级14.0.12--》14.3.6时遇到一个错误:
bash
Running handlers:
There was an error running gitlab-ctl reconfigure:
rails_migration[gitlab-rails] (gitlab::database_migrations line 51) had an error: Mixlib::ShellOut::ShellCommandFailed: bash[migrate gitlab-rails database] (/opt/gitlab/embedded/cookbooks/cache/cookbooks/gitlab/resources/rails_migration.rb line 16) had an error: Mixlib::ShellOut::ShellCommandFailed: Expected process to exit with [0], but received '1'
---- Begin output of "bash" "/tmp/chef-script20240917-12026-tupa61" ----
。。。中间略过。。。。

StandardError: An error has occurred, all later migrations canceled:
Expected batched background migration for the given configuration to be marked as 'finished', but it is 'paused': {:job_class_name=>"CopyColumnUsingBackgroundMigrationJob", :table_name=>"ci_builds_metadata", :column_name=>"id", :job_arguments=>[["id"], ["id_convert_to_bigint"]]}
Finalize it manualy by running
sudo gitlab-rake gitlab:background_migrations:finalize[CopyColumnUsingBackgroundMigrationJob,ci_builds_metadata,id,'[["id"]\, ["id_convert_to_bigint"]]']
原因调查
查询chatgpt,这个错误与数据库迁移失败有关,根据错误日志显示,问题出在某个后台迁移任务未完成。GitLab 在进行某些大表的数据迁移时,会将任务分批次处理,而你的迁移任务被暂停了,导致后续的迁移被中止。
具体原因是 GitLab 的 CopyColumnUsingBackgroundMigrationJob 后台任务没有标记为"已完成",而是处于"暂停"状态,任务没有被完全执行,因此阻止了后续迁移。这个问题通常发生在你升级 GitLab 版本时,GitLab 使用后台迁移任务处理大表(如 ci_builds_metadata 表)的数据,以避免在迁移过程中占用大量资源。
解决方案
1、检查数据库连接
bash
sudo gitlab-rake db:migrate:status
结果显示,无法连接数据库。
2、重启数据库
bash
sudo gitlab-ctl status postgresql
sudo gitlab-ctl start postgresql
3、执行
bash
sudo gitlab-rake gitlab:background_migrations:finalize[CopyColumnUsingBackgroundMigrationJob,ci_builds_metadata,id,'[["id"], ["id_convert_to_bigint"]]']
sudo gitlab-ctl reconfigure
又遇到了Redis无法连接错误:
bash
Caused by:Redis::CannotConnectError: Error connecting to Redis on /var/opt/gitlab/redis/redis.socket (Errno::ENOENT)
但是检查Redis服务,却是正常运行的。咨询chatgpt,有时候 Redis 启动过程中出现问题,可能导致 GitLab 其他组件无法正常启动。可以尝试重启所有 GitLab 组件。
4、执行如下步骤:
bash
sudo gitlab-ctl restart
sudo gitlab-ctl reconfigure
又遇到错误,根据日志信息,执行:
bash
sudo gitlab-rake gitlab:background_migrations:finalize[CopyColumnUsingBackgroundMigrationJob,taggings,id,'[["id"\, "taggable_id"]\, ["id_convert_to_bigint"\, "taggable_id_convert_to_bigint"]]']
然后再执行
bash
sudo gitlab-ctl reconfigure
没有报错, 再执行:
bash
sudo gitlab-rake db:migrate
没有错误,然后检查日志和服务,均已正常。
问题解决,记之。
