Red Hat Summit10.4. Customising timeouts required for Reclaim Space Operation
Depending on the RBD volume size and its data pattern, Reclaim Space Operation might fail with the context deadline exceeded error. You can avoid this by increasing the timeout value.
The following example shows the failed status by inspecting -o yaml of the corresponding ReclaimSpaceJob:
Example
Status:
Completion Time: 2023-03-08T18:56:18Z
Conditions:
Last Transition Time: 2023-03-08T18:56:18Z
Message: Failed to make controller request: context deadline exceeded
Observed Generation: 1
Reason: failed
Status: True
Type: Failed
Message: Maximum retry limit reached
Result: Failed
Retries: 6
Start Time: 2023-03-08T18:33:55Z
You can also set custom timeouts at global level by creating the following configmap:
Example
apiVersion: v1
kind: ConfigMap
metadata:
name: csi-addons-config
namespace: openshift-storage
data:
"reclaim-space-timeout": "6m"
Restart the csi-addons operator pod.
oc delete po -n openshift-storage -l "app.kubernetes.io/name=csi-addons"
All Reclaim Space Operations started after the above configmap creation use the customized timeout.
