In that case there is a workaround but I would recommend upgrading to 4.2 if you can.

I did not test the workaround:

You can add to /usr/share/ovirt-engine-dwh/packaging/dbscripts/upgrade/

a file called

04_01_0025__updated_vm_interface_history_id_to_bigint.sql

with the same content as in my patch:

_____________

-- Update vm_interface_* statistics table history_id to bigint

SELECT fn_db_change_column_type('vm_interface_daily_history', 'history_id', 'integer', 'bigint');

SELECT fn_db_change_column_type('vm_interface_hourly_history', 'history_id', 'integer', 'bigint');

SELECT fn_db_change_column_type('vm_interface_samples_history', 'history_id', 'integer', 'bigint');

_____________

and run engine-setup

engine-setup drops all views, makes the updates to the db and recreates the views.

Sorry was looking at the engine database, rather than ovirt_engine_history database.

When running

SELECT fn_db_change_column_type('vm_interface_daily_history', 'history_id', 'integer', 'bigint');

I get

ERROR: cannot alter type of a column used by a view or rule
DETAIL: rule _RETURN on view v4_1_statistics_vms_interfaces_resources_usage_daily depends on column "history_id"

Thanks Shirly,

unfortunately Microsoft sent your reply to my Junk Email folder so I have only noticed it today.

Is there any instructions on how to run the script? I can't find any tables or views with the vm_interface_daily_history, etc columns.

I'm not a database expert.

Hi,

This was fixed in https://bugzilla.redhat.com/show_bug.cgi?id=1541924

in version 4.2.2.

I believe you can update manually the history_id field in tables - vm_interface_daily_history, vm_interface_hourly_history, vm_interface_samples_history

from integer to bigint and it should fix the issue, but I did not test on 4.1.

like in:

https://gerrit.ovirt.org/#/c/87139/4/packaging/dbscripts/upgrade/04_02_0020__updated_vm_interface_history_id_to_bigint.sql

Best,
