Hello,
I had a ovirt-engine-4.3.0 that I am migrating to a new machine. I have done a backup of
that machine but the restore fails on the new machine.
Fresh install of centos and the 4.3.3 ovirt-engine.

If this is a problem while restoring a 4.3.0 backup to a 4.3.3 engine is it possible to
install the 4.3.0 version?
Following the installation part of the release notes of 4.3.0 will result in 4.3.3 being
installed.

This means that in your source database, and therefore in the backup,
you have two rows in the table 'external_variable' with var_name
'fence-kdump-listener-heartbeat'.
1. How to fix this, currently?
If you still have access to the old database, try checking this table,
these two columns, then try guessing which one is needed, and remove
the other. Or perhaps remove both, if ovirt-fence-kdump-listener can
re-add it. No idea, adding Martin.
If you only have the backup file, I guess you'll somehow have to
manually fix its content. Didn't try that myself, but I think you can
try something like this:
1.1. pg_restore should not have failed in the middle, only exited with
errors. So it did restore everything except for the constraint. So
start with the existing restored database, remove the offending row,
(re-)create the constraint, then run backup, untar the result, also
untar the original backup elsewhere, then copy the "fixed" engine db
dump to replace the one in the original backup, tar it back up, then
try to clean up the database and restore again.
1.2. Alternatively, patch engine-backup for now to ignore this error
(search for "IGNORED_ERRORS"), then try again (after cleaning up db),
then add the constraint after restoring.
Please tell us if you must go this way (not having the old engine
anymore) and need help.
2. Not sure why the constraint didn't prevent adding the second row in
the first place - it constraint existed "forever" (was added together
with the table, not after it, in 3.5, bz 1079821). Adding Eli.
3. Not sure what flow caused adding the second row. Briefly looking at
the code that adds it, can't find something obvious. You might give us
a clue by checking the _update_date col in that table, and then check
relevant logs around the time it was added.
Sorry if this isn't very helpful. It's quite a weird problem.

install the 4.3.0 version?
Following the installation part of the release notes of 4.3.0 will result in 4.3.3 being

I don't think it's related. I think it would have failed with any
other version the same way.

Hello,
Thanks for taking the time,
In the meantime I did a new installation on a new machine and imported the old storage
domain and then imported the vm's so I am back that way. More downtime than I would
have liked but hey it is my home environment that I treat like almost like an enterprise
environment since I am a geek. :)
I checked the old machine now and noticed it has a lot of errors. Didn't notice the
kernel sense errors about the device before only that I would get strange problems in the
engine which I know think is related to the disk errors.
Best Regards
Magnus
