Title:
"nova server-group-list" doesn't show members of the group
Status in OpenStack Compute (Nova):
Fix Committed
Status in OpenStack Compute (nova) icehouse series:
Fix Released
Bug description:
With current devstack I ensured I had "GroupAntiAffinityFilter" in
scheduler_default_filters in /etc/nova/nova.conf, restarted nova-
scheduler, then ran:
nova server-group-create --policy anti-affinity antiaffinitygroup
nova server-group-list
+--------------------------------------+-------------------+--------------------+---------+----------+
| Id | Name | Policies
| Members | Metadata |
+--------------------------------------+-------------------+--------------------+---------+----------+
| 5d639349-1b77-43df-b13f-ed586e73b3ac | antiaffinitygroup |
[u'anti-affinity'] | [] | {} |
+--------------------------------------+-------------------+--------------------+---------+----------+
nova boot --flavor=1 --image=cirros-0.3.1-x86_64-uec --hint
group=5d639349-1b77-43df-b13f-ed586e73b3ac cirros0
nova list
+--------------------------------------+---------+--------+------------+-------------+--------------------+
| ID | Name | Status | Task State |
Power State | Networks |
+--------------------------------------+---------+--------+------------+-------------+--------------------+
| a7a3ec40-85d9-4b72-a522-d1c0684f3ada | cirros0 | ACTIVE | - |
Running | private=10.4.128.2 |
+--------------------------------------+---------+--------+------------+-------------+--------------------+
Then I tried listing the groups, and it didn't print the newly-booted
instance as a member:
nova server-group-list
+--------------------------------------+-------------------+--------------------+---------+----------+
| Id | Name | Policies
| Members | Metadata |
+--------------------------------------+-------------------+--------------------+---------+----------+
| 5d639349-1b77-43df-b13f-ed586e73b3ac | antiaffinitygroup |
[u'anti-affinity'] | [] | {} |
+--------------------------------------+-------------------+--------------------+---------+----------+
Rerunning the nova command with --debug we see that the problem is in nova,
not novaclient:
RESP BODY: {"server_groups": [{"members": [], "metadata": {}, "id":
"5d639349-1b77-43df-b13f-ed586e73b3ac", "policies": ["anti-affinity"],
"name": "antiaffinitygroup"}]}
Looking at the database, we see that the instance is actually tracked as a
member of the list (along with two other instances that haven't been marked as
deleted yet, which is also a bug I think).
mysql> select * from instance_group_member;
