"cinder-manage db sync 24" failed when dropping column cgsnapshot_id from the snapshots table. The reason that drop column failed was because of the foreign key constraint. MySQL cannot drop column until the foreign key constraint is removed. So the solution is to remove the foreign key first, and then drop the column. This affects the cgsnapshot_id column in the snapshots table and the consistencygroup_id column in the volumes table. Change-Id: I89d5016be450ec91c7a7b1c42803add3f62c88df Closes-Bug: #1368213
