ovirt node pxe and thinpool errror in status
by Gianluca Cecchi
Hello,
I'm experimenting to install ovirt ng node 4.2 via pxe and it seems all
went ok.
Only problem I have is that opening terminal session I get this traceback
that seems related to thinpool
Traceback (most recent call last):

Any hint?
I installed from 4.2 iso and then applied the
ovirt-node-ng-image-update-4.2.1.1-1.el7.centos.noarch yum update
The problem remains
At the moment it is not linked with any engine, also installed.
I can go to the Admin Console web page and I see, clicking inside
"Virtualization" left tab, that on the right dashboard I have a yellow
triangle to the right of the "Health" word...
But I don't exactly understand the source of the warning...
Thanks for any hint related,

dns vm and ovirt
by Nathanaël Blanchet
Hi all,
I'd need some piece of good practice about dealing a DNS server in or
out of ovirt.
Until now we never wanted to integrate the DNS vm into ovirt because of
the strong dependency. if the DNS server fails for any reason, it
becomes difficult ot join the webadmin (except with a static etc hosts)
and the nodes may become unvailable if they had been configured with fqdn.
We could consider a DNS failover setup, but in a self hosted engine
setup (and more globally an hyperconverged setup) , it doesn't make
sense of setting up a stand alone DNS vm outside of ovirt.
So what about imitating engine vm status in a hosted engine setup? Is
there a way to install the DNS vm outside of ovirt but on the ovirt host
(and why not in a HA mode)?
Second option could be installing the named service on the hosted engine vm?
Any suggestion or return of experience would be much appreciated.

Setting up a LDAP conf

Content-Type: text/plain; charset="iso-8859-1"

Hello,
I have an OpenDJ LDAP server, and I need some help to do query on a specifi=
c filter search.
We can't figure out how to create a "aaa/profile1.properties" file with the=
se configs.
This is how we can filter the users with ldapsearch on our ldap server:
-H ldaps://server:port -D uid=3Duser,ou=3DOU,dc=3DSERVER,dc=3Dcom,dc=3Dbr -=
W -b ou=3Daa,dc=3Dbb,dc=3Dcc,dc=3Ddd uid=3Djose.fernandes
- My configuration does not permit I search the users on base, so I need t=
o do this filter on "ou=3Daa,dc=3Dbb,dc=3Dcc,dc=3Ddd"
- Port is different from common.
Someone can help me to create the config file?
Regards,
Jos=E9 Fernandes

Quick question about oVirt 3.6 and vdsm log in DEBUG mode (apprently by default??)
by Christopher Cox
We're running oVirt 3.6 on 9 Dell Blades but with just two fairly fat
fabrics, one for LAN stuff, ovirtmgmt and one for iSCSI to the storage
domains.
15 VM Storage Domains
iSCSI has 4 paths going through a 40Gbit i/o blade to switch
115 VMs or thereabouts
9 VLANS, sharing an i/o blade with ovirtmgmt 40Gbit to switch
500+ virtual disks
What we are seeing more and more is that if we do an operation like
expose a new LUN and configure a new storage domain, that all of the
hyervisors go "red triangle" and "Connecting..." and it takes a very
long time (all day) to straighten out.
My guess is that there's too much to look at vdsm wise and so it's
waiting a short(er) period of time for a completed response than what
vdsm is going to us, and it just cycles over and over until it just
happens to work.
I'm thinking that vdsm having DEBUG enabled isn't helping the latency,
but as far as I know it came this way be default. Can we safely disable
DEBUG on the hypervisor hosts for vdsm? Can we do this while things are
roughly in a steady state? Remember, just doing the moves could throw
everything into vdsm la-la-land (actually, that might not be true, might
take a new storage thing to do that).
Just thinking out loud... can we safely turn off DEBUG logging on the
vdsms? Can we do this "live" through bouncing of the vdsm if everything
is "steady state"? Do you think this might help the problems we're
having with storage operations? (I can see all the blades logging in
iSCSI wise, but ovirt engine does the whole red triangle connecting
thing, for many, many, many hours).
Thanks,
Christopher

Same with the latest RC, what logs do you need to investigate the problem?

Re: [ovirt-users] Using VDSM to edit management interface
by Kirin van der Veer
Ďakujem Peter, but this doesn't seem to work in my case.
/etc/resolv.conf is regenerated by Network Manager after a reboot and my
domain settings are lost.
Your comments regarding the reliance on DNS make sense for most
installations, but in my case oVirt is a secondary service that I would not
expect to run unless our core infrastructure is working correctly.
I'm hesitant to edit /etc/hosts directly, since that can lead to confusion
when the underlying IP addresses change.
For now I will hardcode the IPs of my servers.
It's frustrating (and surprising) that there is not an easy way to do this.
Kirin.

ovirt 4.2.2-rc3 switching from legacy to OVS..
by Thomas Davis
I'm getting further along with 4.2.2rc3 than the 4.2.1 when it comes to hosted engine and vlans.. it actually does install
under 4.2.2rc3.
But it's a complete failure when I switch the cluster from Linux Bridge/Legacy to OVS. The first time I try, vdsm does
not properly configure the node, it's all messed up.
I'm getting this in vdsmd logs:

IOError: [Errno 19] ovirtmgmt is not present in the system
So something is dreadfully wrong with the bridge to ovs conversion in 4.2.2rc3.

Host can not boot any more with current kernel
by Jonathan Baecker
Hello everybody,
Today I update my engine, from 4.2.1.6 to 4.2.1.7 and later I update two
hosts. All are running on CentOS 7.4
Now they have the kernel 3.10.0-693.21, one host I can start normal and
the other one always reboot short after the menu where I can select the
kernel. There is not even an error message and I can not switch to the
boot log screen.
The same behavior I have with kernel 3.10.0-693.17. Kernel *.11 and
older are working.
Have any body experience this issue and know what to do?
Regards
Jonathan
