I think the root cause is that ovirt do not manage the iscsi initiator on
the hosts.

If we had an option to set the initiator when adding a host, like the way
you
set the host password, it would be hard to have such bugs.

Can you file a bug about this?

Re: [ovirt-users] HELP Upgrade hypervisors from CentOS 6.8 to CentOS 7

2016-09-05 Thread VONDRA Alain 
To resume the situation and be the most clear I can.
I have :

-  2 hypervisors (physical) with CentOS 6.8 : HYP1 and HYP2

-  1 oVirt manager 3.5  (physical and not hosted-engine) with CentOS 7.2
And to be able to upgrade to oVirt 3.6 or more I need to upgrade the 2 
hypervisors to CentOS 7.2.
So I began with HYP2, I’ve removed it from the Cluster, and installed it with 
CentOS 7.2, but when I wanted to join it to a new cluster as shown in the doc, 
HYP2 stayed always unresponsive.
So I’ve restored the HYP2 to Centos 6.8, reinstalled it on the previous cluster 
and everything works well, but I really want to upgrade to CentOS 7.2 to be 
up-to-date, because I will have soonly more than two versions late.

If something does not work for you, I think it's best to open a bug
and attach all relevant logs, including hosted-engine-setup and vdsm
logs from the host and all engine logs from the engine vm.
I can't tell from your log snippet why your new host failed to attach
to the storage domain. If it's reproducible, please check/post vdsm logs.

[1] https://www.ovirt.org/documentation/how-to/hosted-engine-host-OS-upgrade/

Is there any other option to upgrade the hypervisors ?

Even if there is another option, the fact that you can't add a host
is probably problematic in itself, no? What if you actually need to
add a host?
Did you try adding a el6 host and it did work?
Best,

Can you assure me that the installation of a physical hypervisor with CentOS 7,

Yes, this should work.

When I wrote [1], it worked for me.

If something does not work for you, I think it's best to open a bug
and attach all relevant logs, including hosted-engine-setup and vdsm
logs from the host and all engine logs from the engine vm.

I can't tell from your log snippet why your new host failed to attach
to the storage domain. If it's reproducible, please check/post vdsm logs.

Even if there is another option, the fact that you can't add a host
is probably problematic in itself, no? What if you actually need to
add a host?

Did you try adding a el6 host and it did work?

Best,

As you say, “This should”, but is there anybody there who tried this operation ?
Is there any other option to upgrade the hypervisors ?

Unlikely, I didn’t save them, I had to rollback the host quickly before the 
Week-end.
All that I can tell, that is all seemed to work well during the installation of 
the host, all the networks were connected to the SAN, but the host didn’t want 
to go UP, still staying unresponsive with the message below from the oVirt 
engine.
Can you assure me that the installation of a physical hypervisor with CentOS 7, 
is possible if I put it on a different cluster than the other host using CentOS

Follow this:
https://www.ovirt.org/documentation/how-to/hosted-engine-host-OS-upgrade/

Simply ignore the steps that refers to the engine VM if you are with the engine 
on a physical system.

Re: [ovirt-users] HELP Upgrade hypervisors from CentOS 6.8 to CentOS 7

2016-09-02 Thread VONDRA Alain 
Hi,
I’ve followed this doc, and hoped to find a solution with it, so I did’nt use 
the hosted-engine –deploy command, I’ve added a new host and at the end of the 
installation, the host stays unresponsive because unable to be attached to the 
same Storage volume .
Engine log :

UNICEF with the message: null

What is the best way to upgrade cleanly and safely ?
Thank you in advance for your advices

Follow this:

Simply ignore the steps that refers to the engine VM if you are with the engine 
on a physical system.

[ovirt-users] HELP Upgrade hypervisors from CentOS 6.8 to CentOS 7

2016-09-02 Thread VONDRA Alain 
Hi,
I'd like to upgrade my oVirt environment from 3.5 to 3.6 and maybe 4, actually 
the manager oVirt is un 3.5 version, installed on a CentOS 7.2 and the two 
hypervisors are installed on CentOS 6.8.
I need anyway to upgrade the hosts to be able to move to 3.6.
I've tried to upgrade the first host, but I had of course issues telling that 
it can't be possible to mix different OS in the same cluster, I've also tried 
to create another cluster to put this host without success.
What is the best way to upgrade cleanly and safely ?
Thank you in advance for your advices
