Hey All,
I ran into this issue myself where I needed to convert a data domain to an
export domain in order to recover virtual guests from a corrupted
ovirt/rhevm instance into a new ovirt/rhevm instance. This wasn't
documented anywhere that I saw but with the help of Itamar Heim and an
well timed email to the list from Igor Lvovsky last night I was able to do
this and wanted to send to the list a documented procedure for how to
modify the metadata of the data domain prior to import as an export
domain. This procedure works for both RHEV-M and Ovirt. Let me know if
you have any questions.

documented anywhere that I saw but with the help of Itamar Heim and an
well timed email to the list from Igor Lvovsky last night I was able to
do this and wanted to send to the list a documented procedure for how to
modify the metadata of the data domain prior to import as an export
domain. This procedure works for both RHEV-M and Ovirt. Let me know if
you have any questions.
glad it worked.
care to wikify for others?
thanks,
Itamar

This is good info. Given that the metadata can be edited is there a way to
redesignate which storage domain should be the master? I have run into a
couple of times in which for various reasons the master domain could not be
reached and another storage domain was elected as master. Is there a way to
force an election or edit the metadata to redesignate the original master
domain back "as master" again?

i heartly suggest to not try and mess with that on your own.
you can move other storage domains to maint, to force engine to
reconstruct the master on another domain.
(again, do *not* do it on your own via metadata)

Itamar, I concur with you.
I am aware of the dangers here (I edited metadata once already to test
recovering a storage domain in a test setup).
It took me a few tries and looking through the code that generate and
manipulates that data to get it right.
However perhaps as a feature request it would be prudent to allow for the
ability to choose or change which domain is the master without taking down
all the other domains. If you have a-lot of domains this really becomes
problematic to play musical chairs with the domains to get the one you want
to be master elected. This also requires you to take down VM's which makes
it even more problematic. Can we get a "make this domain the master"
feature added to the UI/Cli?

i heartly suggest to not try and mess with that on your own.
you can move other storage domains to maint, to force engine to
reconstruct the master on another domain.

Itamar, I concur with you.
I am aware of the dangers here (I edited metadata once already to test
recovering a storage domain in a test setup).
It took me a few tries and looking through the code that generate and
manipulates that data to get it right.
However perhaps as a feature request it would be prudent to allow for
the ability to choose or change which domain is the master without
taking down all the other domains. If you have a-lot of domains this
really becomes problematic to play musical chairs with the domains to
get the one you want to be master elected. This also requires you to
take down VM's which makes it even more problematic. Can we get a "make
this domain the master" feature added to the UI/Cli?
the plan is to remove the need for a master domain to begin with (SDM
feature)

This wasn’t

able to

glad it worked.
Will this work if the recovered storage domain was not
the master?
no. only for nfs storage domain, only if it was master.
care to wikify for others?

I thought I saw mention on the mailing lists of some notion of storage

I thought I saw mention on the mailing lists of some notion of storage
domain import/export is that also in the works?
yes, import existing storage domain, though still not there.
there is also this one, which has some patches already:

Itamar, I concur with you.
I am aware of the dangers here (I edited metadata once already
to test
recovering a storage domain in a test setup).
It took me a few tries and looking through the code that
generate and
manipulates that data to get it right.
However perhaps as a feature request it would be prudent to
allow for
the ability to choose or change which domain is the master without
taking down all the other domains. If you have a-lot of domains this
really becomes problematic to play musical chairs with the
domains to
get the one you want to be master elected. This also requires you to
take down VM's which makes it even more problematic. Can we get
a "make
this domain the master" feature added to the UI/Cli?
the plan is to remove the need for a master domain to begin with
(SDM feature)

i heartly suggest to not try and mess with that on your own.
you can move other storage domains to maint, to force engine to
reconstruct the master on another domain.
(again, do *not* do it on your own via metadata)

Hey All,

instance.
This wasn’t

with the help of

an

Lvovsky last
night I was
able to
do this and wanted to send to the list
a documented

Let me

glad it worked.
Will this work if the recovered storage domain
was not
the master?
no. only for nfs storage domain, only if it was
master.
care to wikify for others?

Hi,
I am having to recreate my engine, and want to recover my old VMs from
the previous Storage Master Data Domain.
A while back, Michael Ayers posted this recipe (the gmane reply feature
won't allow lines longer than 80 chars, even if they were from the original
post :(, so I apologize for the link ) :
http://comments.gmane.org/gmane.comp.emulators.ovirt.user/4428
Should this method still work? I have tried to recreate this with 3.3.1
and can't. I copied over the old Data Domain to a new directory, and
edited the dom_md/metadata file as follows:
http://pastebin.com/U4xJawR8
But when I try to import it, I get:
"Error while executing action: Cannot add Storage Connection.
Storage connection already exists."
and
"Failed to retrieve existing storage domain information."
Here's output from engine.log:
http://pastebin.com/NVdzLDXb
Any clues?
Thanks,
Bob
1 p.m.
can you run mount and see if you have stale connections to the domain?

The only existing mounts on the Host are the loopback mount for the Data
Domain, and the mount from Engine for the ISO Domain.
I can import another Export domain on the same host which was created in
the normal manner (and then 'destroy' it), but I can't import the
converted one.

I guess you mean psql. But I keep getting an authentication error. I
don't see any obvious passwords in the postgresql.conf file, nor in my

I've tried different users - admin, postgres, engine, and I've tried all
of those with the admin password I specified during setup. No dice.
I also tried your offlist suggestion: "psql engine postgres -c 'select

psql: FATAL: Ident authentication failed for user "postgres"

I've tried different users - admin, postgres, engine, and I've tried all of

As a workaroud possibly:
- establish an ssh connection as root with the engine server
- switch to postgres user
[root@f18engine ~]# su - postgres
- connect to engine database
-bash-4.2$ psql engine
psql (9.2.5)
Type "help" for help.
- execute the query
engine=# select connection from storage_server_connections;

As a workaroud possibly:
- establish an ssh connection as root with the engine server
- switch to postgres user
[root@f18engine ~]# su - postgres
- connect to engine database
-bash-4.2$ psql engine
psql (9.2.5)
Type "help" for help.
- execute the query
engine=# select connection from storage_server_connections;
connection
-----------------------------------------------
f18engine.mydomain:/var/lib/exports/iso
f18ovn01.mydomain:gvdata
(2 rows)
It work for me with 3.3.1 on f19
Brilliant, thanks!
Yes this works, and produces:
engine=# select connection from storage_server_connections;
connection
---------------------------------------------
ovirt-vm.smartcity.net:/var/lib/exports/iso
172.16.0.58:/export/VM_EXPORTDOMAIN
172.16.0.58:/export/VM_DATADOMAIN
(3 rows)
So that's strange - the /export/VM_EXPORTDOMAIN is in fact the export
domain I am trying (and failing) to import.
Note that the first time I tried this it failed, because of a firewall
running on the Host. I wonder if that left some bad state in the DB.
So, is there some way I can clear this out?
Thanks,
Bob

sorry Bob, di8d not notice that the p was cut from psql.
the db password is always given by you during installation (you give one
for admin user and one for db)
you can probably see the the db and user name under /var/log/ovirt-engine/
but it should be user postgress and db engine

I guess you mean psql. But I keep getting an authentication error. I
don't see any obvious passwords in the postgresql.conf file, nor in my
setup/install logs. Is there a hardcoded password somewhere?
I've tried different users - admin, postgres, engine, and I've tried
all of those with the admin password I specified during setup. No dice.
I also tried your offlist suggestion: "psql engine postgres -c 'select
connection from storage_server_connections;' with the same result:
psql: FATAL: Ident authentication failed for user "postgres"

Actually you have the option to select [Automatic] for db
configuration during install.
SO in this case possibly it is hardcoded/randomized?

Hi Bob,
you can try the following command:
engine=# delete FROM storage_server_connections where connection =
'172.16.0.58:/export/VM_EXPORTDOMAIN';
this should allow you re-create your storage domain.
I would appreciate if you could file a bug against it.
Thanks,
Bob

Hi Bob,
you can try the following command:
engine=# delete FROM storage_server_connections where connection =
'172.16.0.58:/export/VM_EXPORTDOMAIN';
this should allow you re-create your storage domain.
Thanks Haim!
I would appreciate if you could file a bug against it.
I got into this situation with some unsupported hacking, and am not sure
whether I would have hit this same issue without it or not.
Do you believe this stale data was simply a result of trying to add a
Host while it had a default iptables configuration active? If it's that
simple I'm happy to open the bug. But if it was a result of trying to
manually convert an old Data NFS Domain into an Export NFS Domain that's
not worth opening a bug since an official feature to do this is in
development.
Please advise.
Thanks,
Bob
