Title:
Nova-compute can't start after DB downgrade from juno to havana
Status in OpenStack Compute (nova):
Won't Fix
Bug description:
We downgrade our OpenStack deployment from Juno to Havana, nova-
compute process can't start because of DB schema issue, the
'compute_node_stats' table was created when DB downgrade, see details
in 233_add_stats_in_compute_nodes.py, but it didn't set the 'id'
colume as primary key, this would result in nova-compute booting
failed.
raise result RemoteError: Remote error: DBError (IntegrityError) null value
in column "ID" violates not-null constraint DETAIL:
Failing row contains (2014-12-29 07:37:18.211288, null, null, 0, null,
num_task_None, 1, 1). 'INSERT INTO compute_node_stats (created_at, updated_at,
deleted_at, deleted, key, value, compute_node_id) VALUES (%(created_at)s,
%(updated_at)s, %(deleted_at)s, %(deleted)s, %(key)s, %(value)s,
%(compute_node_id)s) RETURNING compute_node_stats.id' {'deleted': 0,
