[ovirt-users] error adding node.

Hi Sandro,

Yes we are indeed running an nfs data domain over gluster. But what do you mean with no-replica or replica 3?

Hi Sandro,

Thank you for the explanation. We used the manual:
http://community.redhat.com/blog/2014/10/up-and-running-with-ovirt-3-5/http://community.redhat.com/blog/2014/10/up-and-running-with-ovirt-3-5/

Thats why created an local glusterfs storage for the HE. I find it strange that we can start the engine with the local glusterfs or is this just dumb luck?

So you're running NFS data domain over gluster, not just gluster right?
In this case it may work provided you use no-replica or replica 3.

Regards

Erik

Hi,

I hope i can explain properly ;) (my english isnt that good).

This is the situation:

1. We installed a clean install of centos 7 on the host
2. We created an glusterfs share on the host for the engine

Please note that this is a hyper converged setup and it's not supposed to work even in 3.6 yet.

3. We ran hosted-engine --deploy and followed the wizard
4. we get the message to open the VNC connection to install the engine (we use centos 6.7 for the engine)
5. We continue the wizard and get the new vnc connection to install the engine
6. When the engine is running the wizard tries to add the host to the engine and then we get the error that he cannot connect to the engine. (we did get the health ok message. The hosts file and dns servers are working correctly.

Please don't use gluster storage for HE on the same host running Hosted Engine. This is not a supported configuration.

7. We try to add manually the host to the engine because if the wizard stops at that point he cannot try again because there is already an vm running.
8. When we try to add the host via the engine we get the same error message. The one that he cannot connect to the host.

When i try to ssh via the console on the engine to the host it works. What i fing strange is that he almost immidiatly gives the message (within 3 seconds).

I hope this explains the steps we took.

Kind regards

Erik-Jan de Kruijf

Hi,

I am trying to add the first node to an self hosted engine. When i click ok i immidiatly get the error that he cannot connect to host. But if i try to ssh to the host from the engine it works. Can someone please point me to an solution? If any logs are needed please let me know.

Just to clarify, are you trying to add the host running the HE VM using the Web UI? Or are you trying to add the first non-HE related node?

Kind regards,

Erik-jan de Kruijf
