Hi,
I have some general questions I couldn't find answers in the web about ovir=
t-engine migration:
Currently we're running an ovirt-engine 3.0/ ovirt-node 2.3.0 environment,
If we want to migrate to 3.1, do we also have to migrate to 3.2, or is a "s=
imple" update possible, or is it worth to wait with migration until 3.2 has=
been released?
Hint: A migration(import/export) with about 50 VMs is time-intensive, as w=
e need to plan maintenance windows for every VM :/
We also want to test newer ovirt-nodes & default fedora, I didn't find any =
info about operability with ovirt-engine 3.0:
Can we mix 2.3.0 node with latest version under ovirt-engine 3.0 or is ther=
e any problem with vdsm or anything else?
Monitoring:
If we wish to install check_mk (monitoring) on ovirt-node, how can we make =
sure the installation will be persistent?
(Collectd can't be used in our environment)
The alternative would be , to use default fedora installations, customized =
as ovirt-node.
(But this should be our last choice)
Thanks in advance!
Best,
Sven.

Hi,
I have some general questions I couldn’t find answers in the web about
ovirt-engine migration:
Currently we’re running an ovirt-engine 3.0/ ovirt-node 2.3.0 environment,
If we want to migrate to 3.1, do we also have to migrate to 3.2, or is a
“simple” update possible, or is it worth to wait with migration until
3.2 has been released?
in general, no.
ovirt 3.1 supports 3.0 for backward compatibility mode.
Hint: A migration(import/export) with about 50 VMs is time-intensive,
as we need to plan maintenance windows for every VM :/
you should be able to just upgrade your nodes and/or your engine
independently.
We also want to test newer ovirt-nodes & default fedora, I didn’t find
any info about operability with ovirt-engine 3.0:
should be backward compatible.
Can we mix 2.3.0 node with latest version under ovirt-engine 3.0 or is
there any problem with vdsm or anything else?
should work.
(I'm using should, since i don't remember a specific test case for this
wen 3.1 was released, but we it is a goal to not break this).
Monitoring:
If we wish to install check_mk (monitoring) on ovirt-node, how can we
make sure the installation will be persistent?
that's for mike...
(Collectd can’t be used in our environment)
The alternative would be , to use default fedora installations,
customized as ovirt-node.
you don't need too much customizations. you should be able to just "add
host" from the ui pointing to a fedora host (fedora 17 comes with vdsm
in its default repo). you can define the ovirt repo for newer versions.
(But this should be our last choice)
Thanks in advance!
Best,
Sven.

There are a few things you can do:
On a running system, you can install the package(s) using rpm, then go
and manually run persist on each and every file the package installs.
You might still run into issues if the package is not good about
run-time files going into the right places.
The next thing you can do is use plugin tooling to install the package
into an iso image that you would then install on your node machines.
on a separate (non-node) machine,
# yum install ovirt-node-tools
# create a yum repo somewhere that contains the package and all
dependencies (assuming ./repo)
# have a copy of the latest ovirt-node iso locally
(assuming ./ovirt-node-iso.iso)
# run edit-node
edit-node --name=ovirt-node-iso-check_mk --install-plugin=check-mk-agent
--repo=file:///path/to/repo ovirt-node-iso.iso
This will install the package into the iso image itself. When you
install the ISO, the package will be available. You then will need to
configure and persist the configuration files manually.
