Charm Statuses Explanations
WARNING : it is an work-in-progress article. Do NOT use it in production! Contact Canonical Data Platform team if you are interested in the topic.
The charm follows standard Juju applications statuses. Here you can find the expected end-users reaction on different statuses:
Juju Status | Message | Expectations | Actions |
---|---|---|---|
active | any | Normal charm operations | No actions required |
waiting | any | Charm is waiting for relations to be finished | No actions required |
maintenance | any | Charm is performing the internal maintenance (e.g. cluster re-configuration, upgrade, …) | No actions required |
blocked | the S3 repository has backups from another cluster | The bucket contains foreign backup. To avoid accident DB corruption, use clean bucket. The cluster identified by Juju app name + DB UUID. | Choose/change the new S3 bucket/path OR clean the current one. |
blocked | failed to update cluster members on member | TODO: error/retry? | |
blocked | failed to install snap packages | There are issues with the network connection and/or the Snap Store | Check your internet connection and https://status.snapcraft.io/. Remove the application and when everything is ok, deploy the charm again |
blocked | failed to patch snap seccomp profile | The charm failed to patch one issue that happens when pgBackRest restores a backup (this blocked status should be removed when Release v2.46: Block Incremental Backup and SFTP Storage · pgbackrest/pgbackrest · GitHub is added to the snap) | Remove the unit and add it back again |
blocked | failed to set up postgresql_exporter options | The charm failed to set up the metrics exporter | Remove the unit and add it back again |
blocked | failed to start Patroni | TODO: error/retry? | |
blocked | Failed to create postgres user | The charm couldn’t create the default postgres database user due to connection problems |
Connect to the database using the operator user and the password from the get-password action, then run CREATE ROLE postgres WITH LOGIN SUPERUSER; |
blocked | Failed to restore backup | The database couldn’t start after the restore | The charm needs fix in the code to recover from this status and enable a new restore to be requested |
error | any | An unhanded internal error happened | Read the message hint. Execute juju resolve <error_unit/0> after addressing the root of the error state |
terminated | any | The unit is gone and will be cleaned by Juju soon | No actions possible |
unknown | any | Juju doesn’t know the charm app/unit status. Possible reason: K8s charm termination in progress. | Manual investigation required if status is permanent |
