For the record, my hosted-engine still runs el6.
The hosts now run el7.
This means I need to save backup and restore to a new instance?
I do need to upgrade hosted-engine to el7?

I don't get the overall picture, but what I find strange is, the spUUID in my hosted-engine.conf is not found. When I check the NFS hosted-engine storageDomain it reports this same pool ID. Which in my opinion is the reason for the failed ovf / vm.conf auto-import on shared storage is.

So to get this correct I need to backup and reinstall hosted-engine to get the hosted engine working on my reinstalled hosts now runnign el7?

The original (first host) was removed ( about a year a go I removed this one ) and it is also removed from hosted-engine --vm-status overview.

I ran 'hosted-engine --deploy' again on all the hosts because I upgraded all hosts to EL7.

Upgrading hosted-engine from 3.5 on el6 to 3.6 on el7 requires some additional steps:

Adding Didi and Rafael who are working on that flow.
 

( I have als ran engine-setup for the upgrade )

How can I fix this missing spUUID issue? 
Can I manually add this somehow or run somsetup again to fix this?

Did you redeployed also the engine VM on a fresh storage domain or di you just run 'hosted-engine --deploy' again on all the hosts?
If it's just an upgrade you don't have to run 'hosted-engine --deploy' again.

Please follow this guide:

If this would be the solution, I still wonder why there is no existing storagePool for the storageDomain.

I still keep getting

The Hosted Engine Storage Domain doesn't exist. It should be imported into the setup.

I went digging a little further and found this in the engine.log

2016-02-08 22:30:25,083 INFO  [org.ovirt.engine.core.vdsbroker.vdsbroker.HSMGetStorageDomainInfoVDSCommand] (org.ovirt.thread.pool-8-thread-41) [] FINISH, HSMGetStorageDomainInfoVDSCommand, return: <StorageDomainStatic:{name='hostedengine_nfs', id='88b69eba-ef4f-4dbe-ba53-20dadd424d0e'}, 499b208c-9de9-4a2a-97de-30f410b4e6d4>, log id: 56723427

So it looks like it can't find the storage domain. When I check vdsm.log I found an error:

It looks like 499b208c-9de9-4a2a-97de-30f410b4e6d4 is the id it is also trying to connect to in the engine.log.


Can it be I have setup another DC with a master iscsi storage  which is now offline?  ( 1 DC with Cluster,  VMs with hosted engine and master storage FC all up and running.  )

Not sure where to go from here. Can I somehow restart this storage domain / do a new hosted-engine deploy with different settings?

Thanks for your response.

I have reverted the commented entries and restarted ovirt-ha-agent.
Now status on the daemon gives the error again:


Here I'm a bit confused: is this a fresh hosted-engine deployment with 3.6 or an upgrade from an existing 3.5 hosted-engine deployment?

I have  reinstalled host ( complete OS reinstall) and ran hosted-engine --deploy for redeployment on an existing oVirt ( hosted-engine ).

As described in previous mail, during the deployment I got errors about a missing hostedengine.metadata symlink to /var/run/vdsd/storage/... 
I created these by hand and then I ran deployment again and it worked.

 
The hosted engine domain is not shown in the web storage overview...
When I start import it shows a warning: http://screencast.com/t/7HfJ9qWFwb2L

Can I manually import the hostedengine storage? 
( Hosted engine is visible in web interface and I have running VMs on another storage domain ).

It should auto-import it.
Adding Roy here.
 
I believe this auto-import is failing... 
Where can I find logs about this auto-import?

Update:

The OVF_STORE volume will contain the engine VM description in a format that the engine can easily handle.
It will be created by the engine when:
- it imported the hosted-engine storage domain
- the engineVM is visible
- the datacenter is up (you need at least one additional regular storage domain)

Please make sure that all these conditions are met.

If the OVF_STORE is not there or it's not accessible, ovirt-ha-agent will fallback to the initial vm.conf from deployment time. You see a warning since we are failing back to an initial status and this can temporary override your latest customization to the engine VM configuration.


1. I was able to remove the warnirngs about the not found ovf / vm.conf by commenting the conf_volume_UUID, conf_image_UUID entries in the hosted-engine.conf. After a restart of the ovirt-ha-agent the errors were gone. ( I believe this is not a permanent solution ).

Please revert it.
 

2. This morning I noticed the warning in the event log.
"The Hosted Engine Storage Domain doesn't exist. It should be imported into the setup."

It's just a side effect of your point 1, please revert it.
 

Any help would be appreciated.

I have been upgrading our ovirt hosts to el7 to be able to run version 3.6.
When deploying a new host have problems with the shared OVF storage config part.

1. I get an error during deploy:

[ INFO  ] Stage: Setup validation
[ ERROR ] Failed to execute stage 'Setup validation': failed to read metadata: [Errno 2] No such file or directory: '/rhev/data-center/mnt/[NFS3_SHARE]/88b69eba-ef4f-4dbe-ba53-20dadd424d0e/ha_agent/hosted-engine.metadata'
[ INFO  ] Stage: Clean up

It seems the symlink of hosted-engine.metadata is missing.
So I added manually the /var/run/vdsm/storage folder with subfolder 88b69eba-ef4f-4dbe-ba53-20dadd424d0e and symlinks.
Then I reran the hosted-engine deploy and this time all went well.

2. Now when the host is installed I notice the following in the logs

....

So at this point I was a bit stuck.
I removed complete ovirt36 release and installed ovirt35 for the hosted engine deploy.

This time all went without any problem directly.
From there I retried upgrade and same problems again.

I run ovirt hosted-engine on nfs3. I did found https://bugzilla.redhat.com/show_bug.cgi?id=1159314 
I added no_subtree_check and tried deploy again, but again without luck.

I believe the hosted engine configs are not being migrated to the shared storage. And my problem has todo with http://www.ovirt.org/Features/Hosted_Engine_configuration_on_shared_storage

And found  /etc/ovirt-hosted-engine/hosted-engine.conf, 
conf_volume_UUID, conf_image_UUID
 

Hosts run el7
Hosted engine runs el6
Hosted engine storage is through NFS3

Can I import the hosted engine storage in to engine ( in web interface )?
Or how can I create or trigger manually the OVF store the logs complain about?

Paul Groeneweg
