The issue is about quota update in the horizon dashboard where volume deletion status is not updated. 

For example:

We deleted the volume, cinder logs showing the deletion status as success and even in the dashboard's "volume" section as well.

But in the dashboard quota view, the entry for volume existence is still available, and this problem is only for one volume . (not for all volumes) 

We have tried almost all the possible ways suggested in online blogs to remove this volume id. But still that volume is persisting in the dashboard quota.

Could you please guide us what is the best practice to remove this volume id from the quota without affecting the production environment. 

Appreciate your help.

Thank you.

Kind Regards,

Vineet
