Please open a support ticket with Broadcom Support.
Please run thru the steps below and upload those files to the support ticket.
Support will need a copy of the following Openstack databases to review and determine course of action. nova, nova_api, nova_cell0
#osctl exec -it mariadb-server-0 bash
#mysqldump --defaults-file=/etc/mysql/admin_user.cnf --host=localhost <database> /tmp/<database>.sql
#exit
#osctl cp openstack/mariadb-server-0:/tmp/<database>.sql /tmp/<database>.sql
Then you just pull the backup from the manager. Use something like winscp.
