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.
