I am getting CrashLookBackOff error for Percona XtraDB Cluster 8.0.20 in Kubernetes. We are deploying through helm chart. Is it stable version for helm chart, Can someone help on this.

Hi @Laxminarayana Can’t help much if you don’t provide any logs or more detailed information. Have you looked at the mysql error log on the pod with the issue? Have you looked at other K8S logs? Please provide.

@LaxminarayanaPlease use the forum tools to format your output. Hard to read when you just copy/paste.

I can see the error right here in your logs;

Are you sure you are using the latest version of the operator? Looks like v1.6.0 is the current GA version. Please upgrade to that version of the operator before attempting again. If you are indeed on 1.6.0, then this is a serious bug in the operator that needs to be addressed. The parameter wsrep_sst_auth was removed in PXC8 and should not be present in the scripts.

#6

Thanks for your response. I have removed parameter wsrep_sst_auth but it wasn’t worked. We are using helm for deployment but I don’t see updated chart version for Percona Xtradb Cluster and also we are doing continues deployment using argo cd. Here I have attached generated manifest file. Please look into manifest file and help me to resolve this issue.

@Laxminarayana After removing that parameter, what do the mysql logs say?
