Hi Guys,
Currently I've got a Centos machine running the latest ovirt-release.
This machine is using a local raid set containing a directory with
ovirt-based VMs from my previous install. The ovirt install is a
completely fresh install, no storage/VMs have been created yet.
What's the best way to reimport those? I might try to create a new
storage domain and copy all old VMs into it (if that works anyway...) ,
or just reimport the old domain from the web-interface.
Does either trick have any advantage, or is there a best practice I
should adhere to?
Cheers,
Boudewijn

I just tried reimporting my old
storage domains but that doesn't seem to
work:
[root@server data]# pwd
/raid/ovirt-old/data
[root@server data]# ls
1979444d-b79a-494c-8c1a-bcc132e31a04 __DIRECT_IO_TEST__
This is the old data domain I used, and the
1979444d-b79a-494c-8c1a-bcc132e31a04 contains quite a lot of VMs.
When going to the webinterface and doing :
- Storage
- Import domain
- Type: NFS
- export path: $IP:/raid/ovirt-old/data (and
$IP:/raid/ovirt-old/data/1979444d-b79a-494c-8c1a-bcc132e31a04)
Of course I created an entry in /etc/exports in order to be able to
mount this domain by NFS:
[root@leiden data]# exportfs
/raid/ovirt 192.168.1.44/255.255.255.255
/raid/ovirt-old
192.168.1.44/255.255.255.255
And ownership is by user vdsm.
Despite of this it doesn't work. Unfortunately this page
(http://www.ovirt.org/Features/Import_an_existing_Storage_Domain) isn't
of much use either.
How should I do this?

Hi Boudewijn,
First of all, the wiki page you are referring to is a feature page that was never
implemented.
We are currently working on the same feature, this is the correct feature page:
http://www.ovirt.org/Features/ImportStorageDomain .
I will ask that the irrelevant page be removed to avoid any further confusion.
Second, currently, the only way to import a domain is to create an export domain and
import it.
Can you get the old setup-up and create an export domain?
If not, we'll try to help and work around this is issue, but this is going to be very
complex, since this is not supported.
Just to have a general understanding of your setup - your storage on the same machine as
ovirt engine?
I'm assuming you're using web-admin.
What exactly are you doing there? We don't have the import option there as you
mentioned, so I don't understand how you could import an SD that was not export.
Adding the entry to /etc/exports is meaningless.
Do you have the ovfs of the old VMs available?
In the meantime checking for an easier solution than the above, will get back to you on
that.
Regards,
Vered

Dear Vered,
Thank you very much for your reply; I didn't expect this (at first hand)
simple action to be so hard/complex to perform.
hence the feature page you saw, to add this functionality (currently
work in progress)
My machine is indeed a single machine containing both a node,
webinterface and storage.
The old setup has been reinstalled, so I can't get that one to work
anymore. On the other hand I do still have a database dump from it.
I'm using the webadmin indeed and if I go to storage there's a button
saying import domain. In the dialogue that pops up after pressing that
button it's mentioned that I should use a FQDN/IP notation which made me
expect that it uses NFS ;-).
Yes I do have ovf's, this is a directory listing from one of the storage
domains:

How should I go on recovering those VMs?
change the domain into an export domain, attach it, and import the VMs
from it (currently, you can only import an export domain)

(there's another storage doman which has to be converted too but
that's not that relevant imo).
Now I log in onto the webinterface, select storage domain -> import
domain :
Domain function set to export/NFS
export path:
192.168.1.44:/raid/ovirt-old/data/
(192.168.1.44 is the server's IP)
Now this error pops up:
Error while executing action: Cannot add Storage. Storage format V3 is
not supported on the selected host version.
I just had a look for this one and found this bug (in which you
replied... such a small world :) ) :
https://bugzilla.redhat.com/show_bug.cgi?id=1059604
But there's no obvious solution over there.
Despite this the domains are available in the storage domain list but
they're unattached so no use to me.
Am I still missing something?

Interesting: i just tried readding it again (maybe rereading the
storage domain takes a lot of time) but despite it not showing up in
the storage domain list, ovirt's webadmin tells met the repo has
already been added:
Error while executing action: Cannot add Storage Connection. Storage
connection already exists.
Strange.

Hi,
Regarding what to do in order to be able to add the domain, due to the bug you pointed out
(https://bugzilla.redhat.com/show_bug.cgi?id=1059604), the workaround is to move the host
to a datacenter. Check the host's cluster under the web interface - if it does not
list a datacenter, you can move the host to maintenance, select the cluster, click
'edit' and then select a datacenter.
The second error "Error while executing action: Cannot add Storage Connection.
Storage connection already exists." is also a known bug
(https://bugzilla.redhat.com/show_bug.cgi?id=1014966). You need to find the storage
connection and remove it manually from oVirt. This can be done with REST or SDK.
For REST:
1. find the ID of the connection. should be at: <fqdn/ip of
engine>/api/storageconnections . (look for the connection that lists
192.168.1.44:/raid/ovirt-old/data and note it's ID)
2. Send a DELETE request to <fqdn/ip of engine>/api/storageconnections/<ID of
storage connection>
Thanks,
Gadi Ickowicz

Hi Gadi,
My machine is indeed already in a DC, I missed that part of the bug
completely yesterday night ;-).
Regarding the storage connection: okay I'll have it removed.
On the other hand, will readding it by hand (again) help me in getting
my old VMs to work again? I really like ovirt, but having this amount of
problems when reinstalling my hypervisor really spoils the party :(.

the bug is about a host with a cluster not associated with a DC. is your

your cluster associated with a DC?
Yes it is, so my buglink isn't that relevant after all.
Thanks :). Despite of that, my setup still isn't running and I haven't
got a clue on how to get it to work again.

Hi Jason,
Thanks! I'm going to try this after finishing my coffee!
Can you explain to me *why* this will change the situation? I'd like to
have a better understanding about the inner workings of ovirt.

I don't know -- TYPE=0 is what you find in the export domain metadata
files. I'd love to be able to bring back images w/o the export domain
step in the middle...

Hi Guys,
Thank you very much Jason, Itamar, Gadi! I'm almost there thanks to your
help.
My steps were:
- remove the old storageconnection:
$ curl -u "admin@internal:*****" -X DELETE
https://192.168.1.44:443/api/storageconnections/5636a8c3-65b6-44a4-9ba4-e...
-k
I changed version 3 -> 0 in metadata file
And did an import (export NFS):
192.168.1.44:/raid/ovirt-old/data
Currently the box is importing the VMs from the old to the new repository.
But, there's still a last challenge to overcome:
I had this VM with about 2TB storage attached on both my storage domains
(I had another one too). This poses two different problems:
- I can't import the VM from the first storage domain, since not all
disks did reside on this single storage domain. This error pops up
(which is quite logical):
Error while executing action:
downloadbak:
* Cannot import VM. VM's Image does not exist.
Yeah I know I shouldn't have split the VMs resources over multiple
storage domains... I won't make that mistake again. Is there a way to
move these disks from the second "old domain" to the first "old
domain"
so the VM can be reimported?
Furthermore, my storage machine has about 1.4TB free disk space left.
While importing, a copy of a VM is being made... and this particular one
is 2TB. So I'm going to run out of disk space while doing so; is there a
way to move instead of copy a VM while importing it?
Cheers (and thanks a lot for all the help, I really appreciate it!),

Some people have reported success creating an image of the desired size,
then noting the name of this new image, and copying the old image into the
place of the new one, with the new name. Something like that might work, but
I don't have first-hand experience w/ it.

Hi Jason,
Thanks, although that's quite an ugly option, although better than not
being able to do it at all... I'll keep it in mind anyway if everything
else fails.
Well I was wondering: Can't I just copy those images and vm's from the
second storage domain to the first and add those in the metadata?
I might give that a shot tonight.

There's a database element to this as well, that's why I think there's
the "fake" image creation element.

Hi Jason,
Due to lack of viable alternative, I've decided to go and try this
approach. I just had a look at my datafiles:
- these are either 8gb (OS) or 250gb (LVM images)
- can't mount those directly in my host OS (tried because of the next
point)
- I don't know to what VM this image/VM belongs . They're all quite
the same (basic debian install), so determining it just by running
strings etc on those will not be easy
- I can't import the old VMs from the old storage. If I create new
images and dd the old information into those new images the metadata
will not be copied too.
So the only option is not reusing the VM's but creating completely
new ones and determining which disk images are required for these VMs.
Then creating the new image structure and dd'ing the corresponding
images from the old VMs into the new ones. In order to do so I need to
know what data belongs to what VM.
Is there a trick for doing this?
I still do have the database from the old ovirt machine, this might
save me. Will have a look into that one tomorrow.
Cheers,
Boudewijn

Hi Boudewijn,
So we can proceed and recover your data i'd like to know -
1. can you use the db backup? will you lose any important data if you chose to use it?
2, did you have snapshots for your vm?
please answer so we can proceed with it, we can find methods for restoring without having
to perform images copy (and to restore with copying) - but each way has it's
implications.
thanks,
Liron.

Dear Liron,
Sure thank you very much :).
1: Well it's just a database dump. I can import it into a fresh db,
that's no problem.
2: No I did not have snapshots for my VMs as far as I know. I might have
a single one (in order to test/play around), but I will not mind losing it.

Hi Boudewijn,
if you have db backup and you won't lose any data using it - it would be the simplest
approach.
Please read carefully the following options and keep backup before attempting any of it -
for vm's that you don't have space issue with - you can try to previously
suggested approach, but it'll obviously take longer as it requires copying of the
data.
Option A -
*doesn't require copying the disks
*if your vms had snapshots involving disks - it won't work currently.
let's try to restore a specific vm and continue from there - i'm adding here info
- if needed i'll test it on my own deployment.
A. first of all, let's get the disks attached to some vm : some options to do that.
*under the webadmin ui, select a vm listed under the "export" domain, there
should be a disks tab indicating what disks are attached to the vm - check if you can see
the disk id's there.
B. query the storage domain content using rest-api - afaik we don't return that info
from there. so let's skip that option.
1. under the storage domain storage directory (storage) enter the /vms directory - you
should see bunch of OVF files there - that's a file containing a vm configuration.
2. open one specific ovf file - that's the vm that we'll attempt to restore - the
ovf file is a file containing the vm configuration
*within the ovf file look for the following string: "diskId" and copy those ids
aside, these should be the vm attached disks.
*copy the vm disk from the other storage domain, edit the metadata accordingly to have the
proper storage domain id listed
*try to import the disks using the method specified here:
https://bugzilla.redhat.com/show_bug.cgi?id=886133
*after this, you should see the disks as "floating", then you can add the vm
using the OVF file we discussed in stage 2 using the method specified here:
http://gerrit.ovirt.org/#/c/15894/
Option B -
*Replace the images data files with blank files
*Initiate Import for the vm, should be really quick obviously.
*As soon as the import starts, you can either:
1. let the import be done and replace the data, not that in that case the info saved in
the engine db won't be correct (for example, the actual image size..etc)
2. after the tasks for importing are created (you'll see that in the engine log), turn
the engine down immediately (immediately means within few seconds) and after the copy
tasks completes on the host replace the data files and then start the engine - so that
when the engine will start it'll update the db information according to the updated
data files.

Hi Guys,
Thank you for the elaborate information. I'll try to restore the DB
indeed and make sure all the mounts I previously (when creating the
DB-dump) had will be there too.
I also just had a look in my old DB, which I've just restored:
engine=# select vm_name from vm_static;
vm_name

That's looking great. Actually the most important VMs to restore (the
rest are re-created in about 2-3 hours so having to re-create those
instead of restoring would be okayish):
- bacula
- downloadbak
Problem is that both of those are the VMs with the most of the disks
attached.
Just had a look in the databasedump for the vm id's and found this:
COPY disks_vm_map (history_id, vm_disk_id, vm_id, attach_date,
detach_date) FROM stdin;

I created my dump using pg_dumpall > blah.sql and reimported using psql
-f blah.sql .
Despite this :
Schema | Name | Type | Owner
--------+-----------------------------------+-------+--------
public | action_version_map | table | engine
public | ad_groups | table | engine
public | async_tasks | table | engine
public | async_tasks_entities | table | engine
public | audit_log | table | engine
public | base_disks | table | engine
public | bookmarks | table | engine
public | business_entity_snapshot | table | engine
public | cluster_policies | table | engine
public | cluster_policy_units | table | engine
public | custom_actions | table | engine
public | disk_image_dynamic | table | engine
public | disk_lun_map | table | engine
public | dwh_history_timekeeping | table | engine
public | dwh_osinfo | table | engine
public | event_map | table | engine
That table doesn't exist at all... weird. I'm not a postgres guru so
maybe there's some foo involved I haven't seen :).
The mountpoints I created in my initial setup:
engine=# select id,connection from storage_server_connections;
id | connection
--------------------------------------+-----------------------------------------------

Seems great too, I indeed created those.
When restarting ovirt-engine I get in my logs:
2014-03-17 01:50:06,417 ERROR [org.ovirt.engine.core.bll.Backend]
(ajp--127.0.0.1-8702-2) Error in getting DB connection. The database is inaccessible.
Original exception is: UncategorizedSQLException: CallableStatementCallback; uncategorized

ERROR: current transaction is aborted, commands ignored until end of transaction block;
nested exception is org.postgresql.util.PSQLException: ERROR: current transaction is
aborted, commands ignored until end of transaction block
Also the webinterface stays
blank.
Okay that sounds like database permissions:
[root@Xovirt-engine]# cat
/etc/ovirt-engine/engine.conf.d/10-setup-database.conf
ENGINE_DB_HOST="localhost"
ENGINE_DB_PORT="5432"

ENGINE_DB_DRIVER="org.postgresql.Driver"
ENGINE_DB_URL="jdbc:postgresql://${ENGINE_DB_HOST}:${ENGINE_DB_PORT}/${ENGINE_DB_DATABASE}?sslfactory=org.postgresql.ssl.NonValidatingFactory"
I tried to reset the database's password using this in the psql shell:
alter user engine WITH password '********';
(the same password as above)
Still authentication fails, but when I do this:
psql -h localhost -p 5432 -U engine engine
It works fine... O gosh more debugging ;). Any clue where I should have
a look?
I just tried copying the old /etc/ovirt* stuff over /etc/overt* so both
configs and db are sync'ed again. To no avail.
Thanks guys!

For PostgreSQL access you have to check your previous settings in
/var/lib/pgsql/data
relevant files are
pg_hba.conf
and
postgresql.conf
On a standard ovirt 3.3.3 on CentOS 6.5 my config is
pg_hba.conf;
local all all ident
host engine engine 0.0.0.0/0 md5
host engine engine ::0/0 md5
host all all 127.0.0.1/32 ident
host all all ::1/128 ident
If I compare modifications made by engine setup in respect of pre-defined ones:
[root@ovirteng02 data]# diff postgresql.conf postgresql.conf.20140301072333
64,65c64
< # max_connections = 100 # (change requires restart)
< max_connections = 150
---
max_connections = 100 # (change requires restart)
[root@ovirteng02 data]# diff pg_hba.conf pg_hba.conf.20140301072333
71,72d70
< host engine engine 0.0.0.0/0 md5
< host engine engine ::0/0 md5
check also your PostgreSQL version with the original one.

Okay I've finally found some time to fix my problems with the old
storage domains.
I reinstalled the box and it's running fine but I'd love to recover the
old domain I used for downloading stuff.
I just reread your email from march 16th and I'm going to try the thing
you've suggested, so I hope you're still willing to help me :).
Option A -
*doesn't require copying the disks
*if your vms had snapshots involving disks - it won't work currently.
let's try to restore a specific vm and continue from there - i'm adding here info
- if needed i'll test it on my own deployment.
A. first of all, let's get the disks attached to some vm : some options to do that.
*under the webadmin ui, select a vm listed under the "export" domain, there
should be a disks tab indicating what disks are attached to the vm - check if you can see
the disk id's there.
B. query the storage domain content using rest-api - afaik we don't return that info
from there. so let's skip that option.
1. under the storage domain storage directory (storage) enter the /vms directory - you
should see bunch of OVF files there - that's a file containing a vm configuration.
2. open one specific ovf file - that's the vm that we'll attempt to restore - the
ovf file is a file containing the vm configuration
*within the ovf file look for the following string: "diskId" and copy those ids
aside, these should be the vm attached disks.
*copy the vm disk from the other storage domain, edit the metadata accordingly to have
the proper storage domain id listed
*try to import the disks using the method specified here:
https://bugzilla.redhat.com/show_bug.cgi?id=886133
*after this, you should see the disks as "floating", then you can add the vm
using the OVF file we discussed in stage 2 using the method specified here:
http://gerrit.ovirt.org/#/c/15894/
In order to get the disks attached to a VM, I
need to move them into a
new import domain. How should I determine which files to get?
There were multiple VMs in the directory, each having multiple
LVM-based storage domains so I just had a look, I 'm only interested in
images from "Downloadbak".
I found:
engine=# select
image_guid,size,parentid,imagestatus,volume_type,volume_format,active
from images order by parentid;
image_guid | size |
parentid | imagestatus | volume_type | volume_format | active
