I have added a ticket: https://bugzilla.redhat.com/show_bug.cgi?id=1328718

Looking forward to solve!  ( trying to providing as much info as required ).

For the short term, wwhat do I need to restore/rollback to get the OVF_STORE back in the Web GUI? is this all db?

Op wo 20 apr. 2016 om 09:04 schreef Paul Groeneweg | Pazion <paul@pazion.nl>:

Yes I removed them also from the web interface.

Cen I recreate these or how can I restore?

Hi Roy,

What do you mean with a RFE , submit a bug ticket?

Yes please. https://bugzilla.redhat.com/enter_bug.cgi?product=oVirt

 

Here is what I did:

I removed the OVF disks as explained from the hosted engine/storage.

I started another server, tried several things like putting to maintenance and reinstalling, but I keep getting:

Apr 20 00:18:00 geisha-3 ovirt-ha-agent: WARNING:ovirt_hosted_engine_ha.lib.ovf.ovf_store.OVFStore:Unable to find OVF_STORE
Apr 20 00:18:00 geisha-3 journal: ovirt-ha-agent ovirt_hosted_engine_ha.agent.hosted_engine.HostedEngine.config ERROR Unable to get vm.conf from OVF_STORE, falling back to initial vm.conf

Fact it can't find the OVF store seems logical, but now the /var/run/ovirt-hosted-engine-ha/vm.conf is replace with a file conatining only "None".

I tried to set file readonly ( chown root ), but this only threw an error about file not writable, tried different path, but nothing helped.

So I am afraid to touch the other running hosts, as same might happen there and I am unable to start hosted engine again.

I thought OVF would be created automatically again if it is missing, but it isn't...

Can I trigger this OVF, or add it somehow manually? Would deleting the whole hosted_storage trigger an auto import again including OVF?

If this provides no solution, I guess, I have to restore the removed OVF store. Would a complete database restore + restoring folder images/<OVF_STORE_ID> be sufficient? 

Or where is the information about the OVF stores the Web GUI shows stored?

Did you remove it also from the engine via the webadmin or REST? storage tab -> click the hosted_storage domain -> disks subtab -> right click remove the failing ovf
 

Looking forward to resolve this OVF store issue.

Thanks in advance!!!

Hi Roy,

Thanks for this explanation. I will dive into this evening. ( and make a backup first :-) )

Normally the hosted engine only creates 1 ovf disk for the hosted storage?

Thanks for the help.

I am still wondering about the OVF disk ( and event error ) on my hosted storage domain.

My hostedstorage ovf disks ( http://screencast.com/t/AcdqmJWee )  are not being updated ( what I understood is they should be regularly updated ). 

So I wonder, maybe I can remove these OVF disks and they are recreated automatically? ( Similar when removing the hosted storage domain it was added automatically again )

And for this NFS storage domain, is it normal to have 2 OVF disks?

Really looking for a way get these OVF disks right.

Hi Paul,

What you can do to remove them is to run this sql statement at your setup

```sql

-- first make sure this is the disk, dates are taken from your screenshot

SELECT ovf_disk_id, image_guid, imagestatus, _create_date FROM images, storage_domains_ovf_info where ovf_disk_id = images.image_group_id and _create_date > '2016-05-01 11:11:29' and _create_date < '2016-05-01 11:11:31';

-- now delete this disk

DELETE FROM  storage_domains_ovf_info where ovf_disk_id = %what was found in the last query%'

```

Now you can right-click and remove this disk.

Since the disk of the ovirt-engine resides on the hosted_storage domain we can't put this domain into maintenance and fix those kind of issues. There for I would like you to kindly open an RFE and mention you're scenario so we would supply a way to do this kind of operations in a safe way.

Maor thanks for the help and reference.

Op ma 4 apr. 2016 om 09:54 schreef Paul Groeneweg | Pazion <paul@pazion.nl>:

I'd like to add:

- There are 2 OVF stores in my hosted_storage ( hostedengine_nfs ).

- I checked creation time, they are both created around the same time http://screencast.com/t/hbXQFlou 

So hopefully there is some way to update hosted storage sp it can be updated.

[Adding Roy to the thread]

Roy,

Can you please share your insight regarding the hosted engine behavior.

It looks that one of the OVF_STORE disks is not valid and I think that detach/attach of the storage domain might fix the audit log errors.

The question is, if it is possible to do so in hosted engine environment.

Regards,

Maor

This storage domain is my hosted engine storage domain. So I should put it to maintenance and then detach? http://screencast.com/t/kjgNpI7fQ 

Am I still able to use the hosed engine ( web interface) when this stoarge domain is in maintenance and detached?

As I don't want to risk detaching hosted storage storage domain and as a results breaking my whole setup.

Have you already tried to detach and attach the Storage Domain?

Hi Maor,

I am refering to the eventlog, where these ovf errors appear every hour and fill up my eventlog

Hi Paul,

Which problem are you referring, the remove of OVF_STORE disks or the audit log warning?

In the screencast I can see that the Storage Domain is active but I didn't notice any audit log errors.

Hi Maor,

The 3.6.4 did not solve the problem.

Any idea how to fix this issue?

I believe it has something todo with the status of hosted_storage ( 1st entry )  http://screencast.com/t/vCx0CQiXm 

Op za 26 mrt. 2016 om 18:08 schreef Maor Lipchuk <mlipchuk@redhat.com>:

Hi Paul,

Can you please update whether the upgrade for 3.6.4 has helped.

Regarding the OVF_STORE disks, those disks should not be deleted since deleting them might reflect on the Disaster Recovery scenarios

Maor

I believe my problem is related to this bug https://bugzilla.redhat.com/show_bug.cgi?id=1303316

As you can see in the screenshot the hostedengine storage is unassigned and so both ovf_stores are OK, but not linked and therefore  can't be updated?!

So for now I guess I'll wait for update 3.6.4 and cross my fingers and updates solves the event log error.

What happens when I remove them, is it safe?

I checked agent.log and do not see the errors there....

These OVF stores are created on my hosted-engine storage instance. I did not found any reference in the hosted-engine.conf, so you are sure they can't be deleted?

So it holds only info about the hosted-engine disk? So when detaching, do I have any risk destroying my hosted-engine?

I can just detach them in this screen: http://screencast.com/t/ymnzsNHj7e and then re-attach?

I check file permissions, but this looked good compared to the other images. So really strange this eventlog.

Paul

When I check on file there is some data, but not updated: http://screencast.com/t/hbXQFlou

When I check in the web interface I see 2 OVF files listed. What are these for, can I delete them? http://screencast.com/t/ymnzsNHj7e

Hi Paul,

The OVF_STORE disks are disks which preserve all the VMs and Templates OVF data and are mostly use for disaster recovery scenarios.

Those disks can not be deleted.

Regarding the audit log which you got, can you try to detach and attach the Storage once again and let me know if you still get this even log.

Regards,

Maor
