Chapter 6. Troubleshooting upgrade error messages
The following table shows some cephadm upgrade error messages. If the cephadm upgrade fails for any reason, an error message appears in the storage cluster health status.
| Error Message | Description |
|---|---|
| UPGRADE_NO_STANDBY_MGR | Ceph requires both active and standby manager daemons to proceed, but there is currently no standby. |
| UPGRADE_FAILED_PULL | Ceph was unable to pull the container image for the target version. This can happen if you specify a version or container image that does not exist (e.g., 1.2.3), or if the container registry is not reachable from one or more hosts in the cluster. |
