external_status | integer

- max int 0

I am suspecting especially all those *size* columns , please check by extending one by one to BigInt and check if the problem solved

Hi Filip,

could you please share with us complete engine logs using SOS log collector [1] and, if possible, engine database dump, so we can investigate the issue? Also do you remember any steps you have performed before this issue happened?

Thanks

Martin

Subject: ERROR: integer out of range
To: <users-owner@ovirt.org>

Dear guru’s,

Do you have any idea how to fix it? I can’t list any storage domain = no data storage domain is up, so the datacenter is also down.

Thats why I understand this error:
On startup any virtual machine this error:
Action failed due to database connection failure. Please check connectivity to your Database server

Using: Software Version:4.2.4.5-1.el7

PSQL:
engine=# select * from

storage_domains_for_search;
ERROR: integer out of range

In vdsm.log is everything, but on:

engine.log:
