Hi all!!

I had a terrible problem with my blade and I lost the 2 nodes.

"The", as in you had only two nodes, and lost both of them?
 
I have installed a new server as a node  ( ovirt-node-iso-3.6-0.999.201608311021.el7.centos.iso)

This is a very old and long-unsupported version.
If at all possible, I recommend upgrading to 4.4, the currently-supported version.

If you do not want to, or cannot, do the entire upgrade chain, you can consider installing new engine+hosts and import the old storage domains. If you do, please try this first on a test system, to see that it works as expected.
 
but for any reason the data domain don't start. It the same node version.
The ovirt manager is 3.6.7

If I create a new datacenter I can attach a lv from the same lun with the problem..

Someone could help me.. I have been working to solve the problem fron the saturday..

Please provide more details:

1. A brief description of your architecture/topology - number of hosts, clusters/DCs, storage, networks, etc.
2. What happened so far, as much as you can tell
3. What exactly you try to do now, at which times exactly, and what happens, including exact times
4. All relevant logs, and make sure you can find the times you mention above in the logs. These include:
from the engine: /var/log/ovirt-engine
from hosts: /var/log/vdsm

Best regards,
