[ovirt-users] ERROR: update or delete on table "luns" violates foreign key constraint...

[Aleksey Chudov]

Hi,

I have two-node self hosted engine cluster with iscsi shared storage. Every
ovirt-engine restart produces the following error in
/var/log/ovirt-engine/engine.log. After that engine works without any
problems.

How to fix it?

[ovirt-users] ovirt reports an Intel(R) Xeon(R) CPU E5-2667 v3 @ 3.20GHz as a Intel SandyBridge Family?

[gflwqs gflwqs]

Hi,
I have registered a new DELL R730 machine in ovirt 3.5.6 this server type
has a Intel(R) Xeon(R) CPU E5-2667 v3 @ 3.20GHz.
When i try to add a the new host to a cluster with a haswell architecure i
get an error:
"Host xxx moved to Non-Operational state as host does not meet the
cluster's minimum CPU level. Missing CPU features : model_Haswell"

When i look at the hardware tab on the host it says:
CPU Model: Intel(R) Xeon(R) CPU E5-2667 v3 @ 3.20GHz
and
CPU Type: Intel SandyBridge Family

This is not a SandyBridge Family processor?

When i change the cluster to be a SandyBridge Family cluster the host can
be activated.

What are my options?
- Is it a bug i can get a fix for? (I can't upgrade to 3.6)
- Can i  force it to report correctly?
- What am i loosing in terms of functionality/performance if ovirt thinks
its a SandyBridge processor?

Thanks!

You can't put the only existing host in maintenance since Hosted Engine is
running on it and it can't migrate

- shutdown the VMs in your Datacenter
- move the host to local maintenance
- shutdown engine VM
- yum update
- reboot
- exit maintenance

It's a bugged Haswell CPU where the TSX feature has been hardware disabled
by Intel with a microcode upgrade due to an hardware bug:
http://www.anandtech.com/show/8376/intel-disables-tsx-instructions-erratum-found-in-haswell-haswelleep-broadwelly

https://bugzilla.redhat.com/show_bug.cgi?id=1218673

You loosed the TSX feature (Transactional Synchronization eXtensions).

Re: [ovirt-users] Network tagging

[Alex Crow]

Just curious, why would you want to bond two different VLAN interfaces? 
It does not make much sense.


You can add a network with a VLAN and then use it on a bonded connection 
or an a single interface, if that's what you mean.


I just wish there was a way to make the VLAN ID optional, so you could 
use it tagged on a host with only a couple of ethernet interfaces, and 
then untagged on an interface on a machine it lots of eth interfaces (eg 
to spread the VLANs over multiple interfaces: imagine a host with 2x10G, 
one would be storage and the other for all VLANs tagged. Another host 
might have 8 or more interfaces, on that each VLAN could be untagged 
per-interface.)

It depends: if your specific applications takes advantages on the haswell

Re: [ovirt-users] Network instability after upgrade 3.6.0 -> 3.6.1

I found this in vdsm.log and I think that could be the problem:

I partially solve the problem.

My host machine has 2 network interfaces with a bond. The bond was 
configured with  mode=4 (802.3ad) and switch was configured in the 
same way.
If I remove one network cable the network become stable. With both 
cables attached the network is instable.


I removed the link aggregation configuration from switch and change 
the bond in mode=2 (balance-xor). Now the network are stable.
The strange thing is that previous configuration worked fine for one 
year... since the last upgrade.


Now ha-agent don't reboot the hosted-engine anymore, but I receive two

First a mail with "ovirt-hosted-engine state transition

Same thing happens fo others two VM.

[ovirt-users] Frustration and Contradictory Guidance?

[Eriks Goodwin]

Hi all, 

I have been working on building a new oVirt 3.6 deployment for more than two 
weeks now and a multitude of things are frustrating my attempts... Would 
someone please point me to the "right" HOWTO article for deploying a 
production-grade oVirt 3.6.x system with HA hosted engine? 

I spent almost two weeks just trying to get the networking straight--only to 
have VDSM overwrite all my hard work and totally break my networking (I was 
using a bonded set of NICs with bridges and VLANs for ovirt-management, 
ovirt-storage, and local-lan.). 

Once I abandoned VLANs and installed a third physical NIC, I was able to 
install the first node and the hosted engine-- but after I got things "working" 
now I receive constantly cycling email messages for ovirt-hosted-engine state 
transition: ReinitializeFSM-EngineStarting, EngineStarting-EngineUp, and 
StartState-ReinitializeFSM 

When I try to follow the instructions to add engines for HA, the system keep 
faulting that it is unable to find the answer file it needs on node 2. 

And now that I finally figured out that I needed to add "another" storage 
domain for the datacenter to initialize, the addition of new hosted-engine 
deployments is blocked by the presence of the attached storage domain. 

So, all of that said is there a HOWTO written specifically for CentOS 7 
that does not want me to kill Network Manager and switch from FirewallD back to 
iptables--and does not assume I want to use glusterfs? 

I have two sets of HP Proliant servers I want to use for this: 4 DL380 G6s and 
4 DL380G5s, plus one G5 which is my initial NFS3 share 

For such an AWESOME project, I find it really disappointing that the 
documentation is so poor/outdated. :-( 

Thanks, 
Eriks

It's hard to say without a detailed log but yesterday we found an issue
with HA services systemd unit files on Centos 7.2.

Today we async released ovirt-hosted-engine-ha-1.3.3.5-1 that should fix it.
Can you please check if you are already with that?
If not please update it and manually restart ovirt-ha-broker and
ovirt-ha-agent services, I'm quite confident the it should be enough.

The oVirt engine runs on a VM, than you need al least two physical hosts
and and some kind of shared storage (NFS, iSCSI, Gluster, FC).

You should run hosted-engine --deploy on the first host, it configures it
and starts the engine VM here.

Then you should run hosted-engine --deploy also the the second host
pointing to the same shared storage. The setup will find the existing
storage domain and it asks is you want to add an host, you have to say yes,
this is host 2.
At this point the setup will ask you the address of the first host to
download an answerfile from there to configure the second host as the first
without having you to manually enter the same data.

The engine VM is on its own dedicated storage domain, you need an
additional one for other VMs.

sorry, can you better explain the issue or add a log?

GlusterFS is just an option. iptables instead of Firewalld and no
NetworkManager are mandatory.

The first thing I'd do is to move that file aside and reinstall the
default from the package, i.e., yum/dnf reinstall sudo.  Make sure
ansible doesn't squash this while you test again.  If that resolves the
problem start looking at the differences between yours and the default
to isolate what & why.  If it doesn't resolve the problem then you need
to look elsewhere of course.

[ovirt-users] 3.6.1 HE install on CentOS 7.2 resulted in unsync'd network

[John Florian]

I'm trying to get a 3.6.1 HE setup going where I have 4 VLANs (VIDs
101-104) for storage networks, 1 VLAN (VID 100) for ovirtmgmt and 1 more
(VID 1) for everything else.  Because I know of no way to manipulate the
network configuration from the management GUI once the HE is running and
with only a single Host, I made the OS configuration as close as
possible to what I'd want when done.  This looks like:

The hosted-engine deploy script got stuck near the end when it wanted
the HA broker to take over.  It said the ovirtmgmt network was
unavailable on the Host and suggested trying to activate it within the
GUI.  Though I had my bonding and bridging all configured prior to any
HE deployment attempt (as shown above), the GUI didn’t see it that way. 
It knew of the bond, and the 4 IFs of course, but it showed all 4 IFs as
down and the required ovirtmgmt network was off on the right side –
effectively not yet associated with the physical devices.  I dragged the
ovirtmgmt net over to the left to associate it the 4 IFs and pressed
Save.  The GUI now shows all 4 IFs up with ovirtmgmt assigned.  But it
is not in sync -- specifically the netmask property on the host is
"255.255.255.0" while on the DC its "24".  They're saying the same
thing; just in different ways.

Since I only have the one Host, how can I sync this?

Re: [ovirt-users] Hosted Engine setup - got " Failed to start service 'ovirt-ha-agent' "

[Will Dennis]

I yum updated my hosts, and it did update ovirt-hosted-engine-ha on all to 
1.3.3.5 (two of my hosts include the one I did the engine install on were 
previously 1.3.3.4, and the third one was 1.3.3.3 for some reason)
Shortly thereafter, I began getting ovirt-hosted-engine state machine emails, 
and when I checked the state of the ovirt-ha-[agent,broker] services, they were 
running. When I got the email saying “EngineStarting-EngineUp”, I checked the 
web UI, and it was available, and I could successfully log into the admin site 
:)

Thanks for your help, and onwards!

[ovirt-users] Cannot retrieve answer file from 1st HE host when setting up 2nd host

[Will Dennis]

Doing a “hosted-engine —setup” on my 2nd oVirt host, and am getting the 
following error:


  --== SYSTEM CONFIGURATION ==--

[WARNING] A configuration file must be supplied to deploy Hosted Engine on an 
additional host.
  The answer file may be fetched from the first host using scp.
  If you do not want to download it automatically you can abort the 
setup answering no to the following question.
  Do you want to scp the answer file from the first host? (Yes, 
No)[Yes]:
  Please provide the FQDN or IP of the first host: 249.26.200.91
  Enter 'root' user password for host 249.26.200.91:

The problem may be slowness of the SSH connection to the 1st host; ever since I 
did the hosted engine setup on the 1st host and it created the ‘ovirtmgmt’ 
bridge et al, it now for some reason takes a long time (~50 sec’s) to SSH into 
the host…
Example: (key exchange was first done from 2nd host to first host)

[root@ovirt-node-02 ~]# time ssh root@ovirt-node-01 uptime
 21:37:33 up 1 day, 10:43,  0 users,  load average: 0.14, 0.15, 0.14

real0m50.185s
user0m0.048s
sys 0m0.006s

So maybe because of that reason, the setup SCP session is timing out?? How can 
I fix this?
