Engine isn't very particular about updating in this case. As long as
any repository is configured where 'yum check-update
ovirt-node-ng-image-update' is true, upgrades from engine will work.
In general, otopi's miniyum is a bit smarter than base yum, so
'check-update ...' is not always a reliable mechanism to verify this,
but yes, a local repo in a non-routed network which presents the
update will show an update from engine.
thanks, i guess configuring repositories in oVirt Node can only be
achieved when using Foreman/Satellite integration, is that correct? i've
just started to use oVirt Node and i'm beginning to realize that things
are a _little_ bit different compared to a standard linux host.
this brings me to another update related question:
right now oVirt Nodes in my test environment can connect to the internet
and there recently was an update available which i applied through the
engine gui, which seemed to finish successfully. i remember wondering
how i could check what actually changend, there was eg. no kernel change
IIRC. today i discovered that on both updated hosts /tmp/imgbased.log
exists and ends in an error:
subprocess.CalledProcessError: Command '['lvcreate', '--thin',
'--virtualsize', u'8506048512B', '--name',
'ovirt-node-ng-4.1.1.1-0.20170406.0', u'HostVG/pool00']' returned
non-zero exit status 5
i have to mention i manually partitioned my oVirt Node host when i
installed it from the installer ISO (because i want to use software
raid).
i used partitioning recommendations from
https://bugzilla.redhat.com/show_bug.cgi?id=1369874 (doubling size
recommendations).
did my oVirt Node update complete successfully?
how can i check this?
why was there an lvcreate error?
'imgbase layout' says:
ovirt-node-ng-4.1.1.1-0.20170406.0
+- ovirt-node-ng-4.1.1.1-0.20170406.0+1
kernel version is:
3.10.0-514.10.2.el7.x86_64
thanks a lot again
