Support and Troubleshooting

If you have questions or need support, please refer to Veeam Kasten Community Support or open a case via https://my.veeam.com.

Supported Kubernetes Versions

Veeam Kasten currently supports deployments running on the following certified Kubernetes distributions and respective OpenShift versions:

Note: Veeam Kasten also does not support distributions/versions that have been declared 'End of Life' status as defined by their respective entity/community/vendor (in other words, distributions/versions for which maintenance is not provided anymore by their supporting entity/community/vendor).

Kubernetes	RedHat Openshift	Notes
1.31		Respective OpenShift version is not supported yet
1.30	4.17
1.29	4.16
1.28	4.15
1.27	4.14	Kubernetes version only supported when deployed as an OpenShift cluster
1.26	4.13	Kubernetes version only supported when deployed as an OpenShift cluster
1.25	4.12	Kubernetes version only supported when deployed as an OpenShift cluster

Gathering Debugging Information

Admin users running 4.5.7 or later can get support logs from the System Information page under the Settings menu in the navigation sidebar.

Alternatively, if you run into problems with Veeam Kasten, please run these commands on your cluster as a first step to get information to support. The script assumes that your default kubectl context is pointed to the cluster you have installed Veeam Kasten on and that Veeam Kasten is installed in the kasten-io namespace.

$ curl -s https://docs.kasten.io/tools/k10_debug.sh | bash;

By default, the debug script will generate a compressed archive file k10_debug_logs.tar.gz which will have separate log files for Veeam Kasten services.

If you installed Veeam Kasten in a different namespace or want to log to a different file you can specify additional option flags to the script:

$ curl -s https://docs.kasten.io/tools/k10_debug.sh | \
    bash -s -- -n <k10-namespace> -o <logfile-name>;

See the script usage message for additional help.

The debug script can optionally gather metrics from the Prometheus server installed by Veeam Kasten, by specifying the --prom-duration flag with a value indicating the desired duration (e.g. "1d", "3h25m"). The start time of the metric collection is implicitly assumed to be the current time less the specified duration, but can be adjusted with the --prom-start-time flag to specify a time in the past. The format is either the simple duration string that is accepted by the duration flag, or a string that is parsable with the date command, which could be a timestamp or a free form relative or absolute time specification. For example:

$ curl -s https://docs.kasten.io/tools/k10_debug.sh | \
    bash -s -- --prom-duration 4h30m --prom-start-time "-2 days -3 hours"

would collect 270 minutes of metrics starting from 51 hours in the past.

Note

Metrics capture only works with the Prometheus instance installed by Veeam Kasten. The specified duration directly impacts the size of the captured metrics data so constrain the duration accordingly. One can also consider using the --prom-metrics-only flag to separate the collection of metrics from the collection of the logs.

Application Debug Information

If you are having issues with a particular application, please also gather the following information.

# Get Application Information
$ kubectl get pvc -oyaml --namespace <APP NAMESPACE>
$ kubectl api-resources --verbs=list --namespaced -o name | \
    xargs -n 1 kubectl get --show-kind --ignore-not-found --namespace <APP NAMESPACE>

Please also get the Helm status:

# If deployed via Helm
$ helm status <RELEASE NAME> --namespace=<APP NAMESPACE>

Veeam Kasten Tools

The k10tools binary has commands that can help with validating if a cluster is setup correctly before installing Veeam Kasten and for debugging Veeam Kasten's micro services.

To learn more about this, see Veeam Kasten Tools.

Storage Class Validation

k10tools provides an option to validate storage classes via CSI Capabilities Check or Generic Volume Snapshot Capabilities Check commands. It is also possible for admin users to validate storage classes from the Veeam Kasten dashboard, under the System Information page of the Settings menu in the navigation sidebar. The state "Unknown" is shown until validation is run.
