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
hostengine engine 0.0.0.0/0 md5
hostengine engine ::0/0 md5
hostall all 127.0.0.1/32 ident
hostall 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
< hostengine engine 0.0.0.0/0 md5
< hostengine engine ::0/0 md5
check also your PostgreSQL version with the original one.
HIH,

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 - Blank template mail nagios bacula debian-template jabber downloadbak vpn (9 rows) 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.

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

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.

Re: [Users] Reimporting storage domains after reinstalling ovirt
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-e598dc60a4e4 -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?

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 :(.

Re: [Users] Reimporting storage domains after reinstalling ovirt
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: /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 /api/storageconnections/ Thanks, Gadi Ickowicz - Original Message - From: "Boudewijn Ector" To: users@ovirt.org Sent: Monday, March 10, 2014 1:00:35 AM Subject: Re: [Users] Reimporting storage domains after reinstalling ovirt > > > (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.

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.

Re: [Users] Reimporting storage domains after reinstalling ovirt
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.
