Upgrade the NetApp Trident Software
contains the installer for Trident 21.04, but installations that have been upgraded from the previous version and were configured to use a NetApp backend will still be running Trident 20.04 after the upgrade to .
[sysadmin@controller-0 trident(keystone_admin)]$ tridentctl -n trident version
+----------------+----------------+
| SERVER VERSION | CLIENT VERSION |
+----------------+----------------+
| 20.04.0 | 21.04.1 |
+----------------+----------------+
Before upgrading Kubernetes to version 1.19, the running version of Trident must be updated to 21.04. This will not disrupt any containers that are already running, but will cause a brief outage to the NetApp Trident control plane.
The steps are as follows:
Locate the
localhost.yamlfile that was used originally to install Trident, as described inConfigure an External NetApp Deployment as the Storage Backend <configure-an-external-netapp-deployment-as-the-storage-backend>.Add the line
trident_force_reinstall: trueto the file.Run the
install_netapp_backend.ymlplaybook again as per Run Playbook step of sectionConfigure an External NetApp Deployment as the Storage Backend <configure-an-external-netapp-deployment-as-the-storage-backend>.On completion, verify that the Trident server version has been updated:
[sysadmin@controller-0 trident(keystone_admin)]$ tridentctl -n trident version +----------------+----------------+ | SERVER VERSION | CLIENT VERSION | +----------------+----------------+ | 21.04.1 | 21.04.1 | +----------------+----------------+
