I am trying to eat own dog food. Infrastructure as code...
So.. I have taken three physical servers. Setup all the base packages, set
NICs, NTP, DNS, collected disk UUIDs etc..
The servers are prepped.
And one server has cockpit and ovirt-engine installed... and service
started.
I have a pair of nodes which service DNS / NTP / FTP / AD /Kerberos / IPLB
etc..
ns01, ns02
These two "infrastructure VMs have HA Proxy and pacemaker and I have set to
have "HA" within ovirt and node affinity.
But.. within HAProxy, the nodes use to be able to call the STONITH function
of KVM to
I use to have hand built CentOS+KVM + Gluster.
Moved to HCI oVirt controlled system and so far, been very happy with
stability and quality.
One feature that was working in old "hand build" version was fencing.
I have an old APC master switch AP9606. I use to have and use it for
master switch
I have for many years used gluster because..well. 3 nodes.. and so long as
I can pull a drive out.. I can get my data.. and with three copies.. I have
much higher chance of getting it.
Downsides to gluster: Slower (its my home..meh... and I have SSD to avoid
MTBF issues ) and with VDO.. and thin
rt"
Off to find the next "feature"
:)

Seems like this could be my issue
This could be where had issue with rebuild of ovirt-engine. And then had
to scrape out the disk files to then import them back in. I then moved the
"old files" into

Can anyone post link. (with examples.. as most documentation for oVirt
lacks this).. where I can power on a VM via CLI or API.
As of now I cannot login to oVirt-Engine. No errors when I restart it..

When I have to shut down cluster... ups runs out etc.. I need a sequence
set of just a small number of VMs to "autostart"
Normally I just use DNS FQND to connect to oVirt engine but as two of my
VMs are a DNS HA cluster.. as well as NTP / SMTP /DHCP etc... I need
those two infrastructure VMs
I tried to post on website but .. it did not seem to work... so sorry if
this is double posting.

gluster commands stop failing) it keeps
saying it can't do that to a cluster gluster node.

When you go under volumes -> Data ->

oVirt engine shows one of the gluster servers having an issue. I did a

some power connections in prep for UPS.

slurp vm out.
Plus.. that means anytime someone sends me a tar of qcow2 and xml.. I have

I rebuilt my lab environment. And their are four or five VMs that really
would help if I did not have to rebuild.
oVirt as I am now finding when it creates infrastructure, sets it out such
that I cannot just use older means of placing .qcow2 files in folders and
.xml files in other folders

Deployment on three node cluster using oVirt HCI wizard.
I think this is a bug where it needs to do either a pre-flight name length
validation, or increase valid field length.
I avoid using /dev/sd# as those can change. And the wizard allows for
this change to a more explicit devices Ex:
