This might be useful when -the repositories are stored somewhere on the network. - -This can be configured from the admin interface: - - - -**Number of access attempts**: The number of attempts GitLab will make to access a -storage when probing a shard. - -**Number of failures before backing off**: The number of failures after which -GitLab will start temporarily disabling access to a storage shard on a host. - -**Maximum git storage failures:** The number of failures of after which GitLab will -completely prevent access to the storage. The number of failures can be reset in -the admin interface: `https://gitlab.example.com/admin/health_check` or using the -[api](../api/repository_storage_health.md) to allow access to the storage again. - -**Seconds to wait after a storage failure:** When access to a storage fails. GitLab -will prevent access to the storage for the time specified here. This allows the -filesystem to recover. - -**Seconds before reseting failure information:** The time in seconds GitLab will -keep failure information. When no failures occur during this time, information about the -mount is reset. - -**Seconds to wait for a storage access attempt:** The time in seconds GitLab will -try to access storage. After this time a timeout error will be raised. - -To enable the circuitbreaker for repository storage you can flip the feature flag from a rails console: - -``` -Feature.enable('git_storage_circuit_breaker') -``` - -Alternatively it can be enabled by setting `true` in the `GIT_STORAGE_CIRCUIT_BREAKER` environment variable. -This approach would be used when enabling the circuit breaker on a single host. - -When storage failures occur, this will be visible in the admin interface like this: - - - -To allow access to all storages, click the `Reset git storage health information` button. - [ce-4578]: https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/4578 [restart-gitlab]: restart_gitlab.md#installations-from-source [reconfigure-gitlab]: restart_gitlab.md#omnibus-gitlab-reconfigure |
