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).

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.
The latest version of k10tools
can be found
here.
It has binaries that are compatible with both Linux
and MacOS
.
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.
