Hi everyone,
One of the requirements behind the system that I am attempting to build
is that there should be no local storage.
i didn't understand if you don't want to use local storage but trying to
use it?

local storage hosts to the same datacenter and cluster. It seems awkward
to have a 1:1:1 ratio of datacenter to cluster to host. Is there
anything that I am missing or is there a reason for why this is the
design in ovirt?
yes, you need a 1:1:1 for now. plan is to remove this need in the future
by allowing to associate a storage domain with a cluster or host
directly rather than only at DC level.
I plan to use the system to provide a service where end-users will make
API calls to create and delete VMs. It will be critical that
oVirt-engine not be a single-point of failure. I can’t seem to find much
information about whether oVirt-engine is designed with redundancy in
mind. Is oVirt capable of a failover or an active-active configuration?
if engine is down, VMs can still continue to run.
for making engine HA, best approach right now is to use clustering
technologies.
Finally, I am attempting to automate registration of hosts to oVirt and
am hitting this when I try to add a local storage domain:
I saw you solved this - but worth mentioning for ovirt-node, it has auto
registration to engine flow.
[oVirt shell (connected)]# create storagedomain --host test1 --type
"Data (Master)" --storage-type "Local on host"
unknown error: 'str' object has no attribute 'export'
Is this a bug with ovirt-shell that I should file or am I doing
something wrong? The host is in maintenance mode, I do not see anything
in the engine logs after I run the command.
Thanks,
Andrey
