Longhorn Cronjob Failed

Hello,

I recently notice that I get an Error from a Cronjob related to my Backups running for the Volumes, saying:

Job longhorn-system/pvc-xxx failed to complete.

I think that the Job is making the real Backup of the Volume from the Taken Snapshot, because if I set the Setting to only make Snapshots there is no Job (and so no Error). I don’t have an Idee how I can start debugging here.
Hope someone can help :slight_smile:

greetings

Could you please provide which Longhorn version you’re using?
Also, could you please check the job’s log and longhorn-manager log to see if there is any clue on this.

I am using Version 1.1.2
I could’nt check the Jobs Log, because ther ist no Pod associate with the Job and the Alert Runbook Tells me to use "kubectl logs ".
The longhorn-manager has Entries about refused TCP Connections to a Cluster IP

Addition: Just checked. This 10.43.0.1 IP dont exist in the Cluster

The 10.43.0.1 is the kube-apiserver IP address.
The problem seems like the Longhorn is unable to access the kube-apiserver.
Could you please check your cluster networking running correctly?

All Network-Pods are up and running.
I don’t experience any other Problems according to Network.
Is there a specific thing I should check?

Nope. Perhaps you could download the support bundle first, and then try to restart the Longhorn manager DaemonSet.

I’m not 100% sure you hit this issue [BUG] High CPU utilization for Longhorn manager sometimes due to exhaustion of all the available sockets because of socket leaking log stream Β· Issue #2778 Β· longhorn/longhorn Β· GitHub or not.
But from the Longhorn manager log you provided, it’s like the Longhorn manager server can’t reach the kube-apiserver.
