Hello,

 

In the kasten version 7.0.8, the backup policy is failing for cephfs PVC (using shallow read-only) during the export phase with the error “permission denied”

 

 Failed to copy artifacts

 Error converting snapshots

 Failed to export snapshot data

 Error creating portable snapshot

 failed running genericVolumeCopy

 failed running copyVolumeData

 Failed to execute copy volume data pod function

 Failed to create and upload backup

 Failed to exec command in pod

 command terminated with exit code 1. stdout: stderr: 31mERRORs0m upload error: permission denied

 

Thanks & Regards

Kanika Mahajan

@Madi.Cristil @safiya - this might be better in the Kasten section for help.

@jaiganeshjk 

 Hello @kanika.mahajan,

Please have you follow all steps from our documentation (https://docs.kasten.io/latest/install/storage.html#snapshots-as-shallow-read-only-volumes-cephfs-only).

Starting from Veeam Kasten 7.0.8 there is no need to add annotations to persist the SeLinuxOptions on OCP clusters, it is now setup by default, in this case since you are already on 7.0.8 it is not needed.

Please let me know if you have done the setup in previous version and upgraded to 7.0.8 or not.

Regards,
Rubens

Hello @FRubens ! I tried to remove below annotation and executed a backup policy, But still I am getting permission denied errors

Hello @FRubens ! Yes, I did the shallow read-only setup in version 6.5.11 and it was working before upgrade

Hello @kanika.mahajan,

Thank you for the information.

Please have you already raised a support case for this issue ?

If not please I would like to ask you to raise a case attaching the debug logs, this way we can investigate further to understand the issue.

One more question, Do you setup custom SeLinuxOptions in pods/namespaces ?

Regards

Rubens

Yes @FRubens I already raised the support case and had troubleshooting session with k10 team.

No, I am on OKD(OPENSHIFT) which uses default values from security context constraints.

Thank you @kanika.mahajan .

Will proceed with the investigation in the support case and provide updates there as soon as possible.

Regards

Rubens
