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.
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,
cordialement, regards,
