Related to the issue [BUG] Longhorn CSI prints out many error logs during the CSI backup · Issue #3392 · longhorn/longhorn · GitHub

Are you sure that you are on Longhorn 1.2.4? We have fixed this issue in v1.2.4. Could you double check if you are fully upgraded to Longhorn v1.2.4?

Based on the GitHub ticket above, this issue should be fixed and verified for normal cases. Can you provide the support bundle so that we can check if there is anything weird?

Please let m know, where should I found the support bundle on system. Or give command to create same.

You can generate one via the button in the bottom left of the Longhorn UI, then send it to Longhorn Support Bundle longhorn-support-bundle@Suse.com.

Hi @Jickriya ,

It seems that the volume pvc-de1754b6-c883-41fe-bc3e-16e78ed3557d: is not in attached state which might lead to the error. Can you try to attach that volume to see if it fix the issue?
