Hi all . my live tripleo installation has some garbage in mysql. For example in nova If I go for openstack server list I see my 19 servers.

However in the DB in nova.instances I see 39.

MariaDB [nova]> select id,uuid,node from instances;

Some of these I know that are garbage. Is it acceptable to manually remove entries from the DB or will I break everything ?
