Hello,=20
I'm trying to upgrade our ovirt-engine from 4.0 (centos manually installed)=
to 4.1.0 (appliance) using "hosted-engine --upgrade-appliance".=20
Our test setup :=20
2 hosts with centos 7.3 with ovirt4.0 (latest updates)=20
1 ovirt-engine 4.0 (latest update)=20
This method uses a manual backup from current engine and injects it to new =
appliance. Since "old" ovirt-engine is a manually installed 4.0 (latest ver=
sion) as opposed to an appliance, upgrade process warns that it doesn't rec=
ognise the current engine with a somewhat deprecated message :=20
[WARNING] Unable to detect engine version=20
[WARNING] Unsupported upgrade path=20
This procedure has been designed and tested only for upgrading the engine V=
M from ['3.6'] to ['4.0'].=20
Any other usage is highly experimental and potentially dangerous:=20
Current engine: unknown=20
Selected appliance: 4.1-20170201.1.el7.centos=20
Do you want to abort the upgrade process? (Yes, No) [Yes]: no=20
[WARNING] Proceeding on an unsupported and highly experimental path=20
This fails, according to a bug already posted on https://bugzilla.redhat.co=
m/show_bug.cgi?id=3D1420283 which is resolved in future 4.1.1=20
So I tried to manually patch the file corrected in gerrit https://gerrit.ov=
irt.org/#/c/71965/ and - after multiple tries - it still fails at the end w=
ith the following error :=20

start using appliances.=20

Hello,
I'm trying to upgrade our ovirt-engine from 4.0 (centos manually
installed) to 4.1.0 (appliance) using "hosted-engine --upgrade-appliance".
IIRC we do not support this flow currently. I agree it might be useful.
Would you like to open an RFE bz?
Our test setup :
2 hosts with centos 7.3 with ovirt4.0 (latest updates)
1 ovirt-engine 4.0 (latest update)
This method uses a manual backup from current engine and injects it to new
appliance. Since "old" ovirt-engine is a manually installed 4.0 (latest
version) as opposed to an appliance, upgrade process warns that it doesn't
recognise the current engine with a somewhat deprecated message :
[WARNING] Unable to detect engine version
[WARNING] Unsupported upgrade path
This procedure has been designed and tested only for upgrading
the engine VM from ['3.6'] to ['4.0'].
Any other usage is highly experimental and potentially dangerous:
Current engine: unknown
Selected appliance: 4.1-20170201.1.el7.centos
Do you want to abort the upgrade process? (Yes, No) [Yes]: no
[WARNING] Proceeding on an unsupported and highly experimental path
Indeed.
This fails, according to a bug already posted on
https://bugzilla.redhat.com/show_bug.cgi?id=1420283 which is resolved in
future 4.1.1
It might not be clear from the bug content, but:
1. It only affects RHV, not oVirt.
2. It does not fix your problem. It only allows the upgrade tool in version
4.1 to migrate a 3.6 engine to a _4.0_ appliance (not 4.1).
So I tried to manually patch the file corrected in gerrit
https://gerrit.ovirt.org/#/c/71965/ and - after multiple tries - it still
fails at the end with the following error :
...

When checking upgrade log, there's not much more error information other
than :

Indeed.
If you want to "fix" that, you can try to patch engine-backup - search in
it for VALID_BACKUP_RESTORE_PAIRS, there is a comment about enabling
4.0->4.1 upgrade. But as I wrote, this is not supported, and I am not aware
of anyone testing it - so things might break later on.

This is just unrelated noise, will be cleared by bz 1404253.

I'm not sure if my patched file (runvm.py
<https://gerrit.ovirt.org/#/c/71965/3/src/plugins/gr-he-upgradeappliance/v...>)
should be enough to make it work, but maybe this can bring some new
information to you.
Really hopping that 4.1.1 oVirt will resolve this issue as we are eager to
start using appliances.
Please note that the engine appliance is not really an appliance in the
most strict sense of the word, such as e.g. ovirt-node. Once you install
it, it behaves like a normal machine. To upgrade it, you follow normal
upgrade procedures. So even if you somehow manage to do what you want (by
patching engine-backup and probably fixing other things as needed, or by
opening an RFE bz and waiting for it to be handled), it will not help you
much when you eventually want to upgrade to 4.2 and later. You are of
course welcome to open an RFE for this as well, but it will likely require
quite a lot more work, and not sure it's worth it.
Best,
(I can provide you with more/full log files if necessary)
