Doing the above might be enough for engine-setup to finish, but it might
introduce a risk.
Ideally we should find the root cause leading to this state and:
1. Make sure it can't happen anymore
2. Fully fix the data - might require more than just the above update.
3. Alternatively, add a check earlier and notify the user to fix this
manually.
Adding Dan for further analysis.

Thanks for the report!

Best,

[ovirt-users] problem while updating oVirt from 3.6 to 4.0

[Nelson Lameiras]

Hello, 

Not sure if I should post here, or on the dev mailling list. 

I had a serious problem when upgrading an oVirt cluster from 3.6 to 4.0 (before 
updating to 4.1) 

The error on engine-setup log was : 
"schema.sh: FATAL: Cannot execute sql command: 
--file=/usr/share/ovirt-engine/dbscripts/upgrade/04_00_0930_disallow_boot_protocol_to_be_null.sql"
 

After long hours of debuguing and analysing I found out the problem. On 
database, some entries on table network_attachements had a NULL value which 
were incompatible with the sql file above. 
I'm guessing this is an "exotic situation" which shouldn't exist... in theory 
;) 

Anyway, I'm fairly sure that the solution for this problem would be to patch 
the following file 
'ovirt-engine/packaging/dbscripts/upgrade/04_00_0910_do_not_allow_null_boot_protocol.sql'
 
by adding the following line " update network_attachments set boot_protocol = ' 
NONE ' where boot_protocol is null ;" 

If a dev want to discuss it further, I'll be happy to explain my thoughts on 
this matter. 

cordialement, regards,
