backup has started to fail, and now fails each time

Description

The backup was working but is now failing.

 

I havn't made any changes to the configuration so I don't know how to resolve, apart from re-creating the cluster.  Any hints ?

Thank you for the report.

Due to the no feedback from a long time on requested details we are closing this bug. Please report a new bug with the repeatable test case, if you are still able to reproduce the issue.

Hi  

  • is the operator meant to manage certificate expiration, and re-issue when required ?
    In the case of cert-manager deployment certificates will be re-issue automatically 

  • are the certificates meant to be necessary to connect from the backup pod to the pxc pod ?
    Yes, the operator runs an additional pod and this pod should be able to connect to the cluster.

  • why did the restore pod not have the same connection issues as the backup pod ?
    In the case of restoration, we do not have any additional pods in the cluster.

Some more information - I was able to perform a restore from backup - so it is only backup pods that can't connect to the pxc pod.

Also I discovered that the issue with the backup pod connecting to the pxc pod was due to a certificate expired error reported in the pcx logs container.

2023-04-09T09:35:25.061830Z 0 [Warning] [MY-000000] [Galera] Handshake failed: sslv3 alert certificate expired

Since this was a staging database, I tried deleting the xtradb-ssl and xtradb-ssl-internal secrets (my cluster name is xtradb) hoping that the operator would re-issue them, however it just started working without the secrets, and the backup is now working fine.

So a couple of questions arise from this

  • is the operator meant to manage certificate expiration, and re-issue when required ?

  • are the certificates meant to be necessary to connect from the backup pod to the pxc pod ?

  • why did the restore pod not have the same connection issues as the backup pod ?

Anyway, I'm glad to at least have a workaround if I was to face this issue in production

 

Cheers

, We need to have your CR and log from the logs container as well. As I can see you have a full cluster crush and your backup pod can't connect to your pxc-0 pod.

i've added the logs for the 'pcx' container of the pcx-0 pod as well
