[ovirt-users] ovirt 3.6 hostedengine.metadata, missing OVF_STORE

[Paul Groeneweg | Pazion]

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

....
Feb  5 22:33:08 geisha-2 ovirt-ha-agent:

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?
