Open Stack

Hi *,

I'm struggling with a dashboard error that seems to be wrong, I can't  
seem to find any existing reports but I could have simply missed it so  
please point me to any existing reports about that.

Anyway, a user imported two volumes from Ceph via 'cinder manage' in  
our Train version of OpenStack, we upgraded last week to Ussuri.

One of those two volumes is bootable and the instance is up and  
running with both volumes (extended volume group).

When clicking on the instance details the Horizon dashboard shows a  
red window saying

"Failed to get attached volume."

The dashboard log says:

[Tue Apr 06 09:29:56.197238 2021] [wsgi:error] [pid 10140] [remote  
IP:59482] WARNING horizon.exceptions Recoverable error:  
volume_image_metadata


But I can see both volumes in the details page, so the message seems  
incorrect.
I searched the logs for this error message from before the upgrade but  
couldn't find any. So this seems to be new in Ussuri, I assume.

Does anyone have the same experience with managed volumes?

Thanks and best regards,
Eugen
