Re: [ovirt-users] Unable to add Hosts to Cluster

[Mark Steele]

We have found a resolution to this issue which is a bit convoluted - and
still does not explain why this started in the first place. Once we have
prepped a HV server to be added (all the NIC's are ready, selinux,
networkmanager, firewalld, etc have been disabled, we have to do the
following:

yum install librbd1
rm /etc/yum.repos.d/CentOS-Base.repo (yes... delete the base repo...)
vi /etc/yum.repos.d/CentOS-Vault.repo
add the following:
 [vault]
 name=CentOS-$releasever - Extras
 
#mirrorlist=http://vault.centos.org/?release=$releasever&arch=$basearch&repo=extras
 baseurl=http://vault.centos.org/centos/7.0.1406/os/x86_64/
 gpgcheck=0
 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7

vi /etc/yum.repos.d/ovirt-3.5-dependencies.repo
 edit baseurls as show below:
 [ovirt-3.5-glusterfs-epel]
 name=GlusterFS is a clustered file-system capable of scaling to
several petabytes.
 
baseurl=https://download.gluster.org/pub/gluster/glusterfs/old-releases/3.6/3.6.1/RHEL/epel-7/x86_64
 enabled=1
 skip_if_unavailable=1
 gpgcheck=0
 [ovirt-3.5-glusterfs-noarch-epel]
 name=GlusterFS is a clustered file-system capable of scaling to
several petabytes.
 
baseurl=http://download.gluster.org/pub/gluster/glusterfs/old-releases/3.6/3.6.1/RHEL/epel-7/noarch
 
#baseurl=http://download.gluster.org/pub/gluster/glusterfs/LATEST/EPEL.repo/epel-$releasever/noarch
 enabled=1
 skip_if_unavailable=1
 gpgcheck=0

yum remove ovirt-release35
yum remove vdsm
yum remove libvirt

yum install ovirt-release35-002-1
yum install libvirt-1.1.1-29.el7
yum install vdsm-4.16.7-1.gitdb83943.el7

We can then successfully add the HV into the cluster.

This is using CentOS 7.0.1406 (Core) as the host OS and oVirt 3.5.0.1-1.el6

If anyone has any questions please feel free to ask.

I doubt that.
I still suspect the libvirt auth. issue.
Nevertheless, as commented more than once, you are running on somewhat old
version with a recent CentOS version. Not sure this combination is tested
or anyone's running it.

 You are seeing https://bugzilla.redhat.com/show_bug.cgi?id=126 ,
 which is a result of a default change of libvirt and was fixed in later
 versions of oVirt than the one you are using.
 See patch https://gerrit.ovirt.org/#/c/76934/ for how it was fixed,
 you can probably configure it manually.

[Mark Steele]

​Is it possible that the HostedEngine became corrupted somehow and that is
preventing us from adding hosts?

Is creating a new hosted engine an option?

 We have four other hosts that are running this same configuration
 already. I took one host out of the cluster (forcefully) that was working
 and now it will not add back in either - throwing the same SASL error.

 We are looking at downgrading libvirt as I've seen that somewhere else
 - is there another version of RH I should be trying? I have a host I can
 put it on.

Re: [ovirt-users] Unable to add Hosts to Cluster

[Mark Steele]

At this point I'm wondering if there is anyone in the community that
freelances and would be willing to provide remote support to resolve this
issue?

We are running with 1/2 our normal hosts, and not being able to add anymore
back into the cluster is a serious problem.

Re: [ovirt-users] Unable to add Hosts to Cluster

[Mark Steele]

Thank you Alex.

I guess the first step is to get my existing hosts back into the cluster.
I'm going to try to manually apply the patch that Yaniv sent over to see if
I can get them back in.

Mark

 We have four other hosts that are running this same configuration
 already. I took one host out of the cluster (forcefully) that was working
 and now it will not add back in either - throwing the same SASL error.

 We are looking at downgrading libvirt as I've seen that somewhere else
 - is there another version of RH I should be trying? I have a host I can
 put it on.

Re: [ovirt-users] Unable to add Hosts to Cluster

[Alex K]

For a proper upgrade there are specific steps that you follow for each host
and the engine.

I usually upgrade the hosts first then the engine. If you have spare
resources so as to put hosts at maintenance then the upgrade should be
seamless. Also i think you need to go strp by step: 3.5 -> 3.6 -> 4.0 ...
etc

In case you have a similar test setup you may try it first there.

Re: [ovirt-users] Unable to add Hosts to Cluster

Thank you very much!

Question - is upgrading the ovirt installation a matter of just upgrading
the engine? Or are there changes that are pushed down to each host / vm?

You are seeing https://bugzilla.redhat.com/show_bug.cgi?id=126 , which
is a result of a default change of libvirt and was fixed in later versions
of oVirt than the one you are using.
See patch https://gerrit.ovirt.org/#/c/76934/ for how it was fixed, you can
probably configure it manually.

Re: [ovirt-users] Unable to add Hosts to Cluster

[Mark Steele]

We are using CentOS Linux release 7.0.1406 (Core) and  oVirt Engine
Version: 3.5.0.1-1.el6

We have four other hosts that are running this same configuration already.
I took one host out of the cluster (forcefully) that was working and now it
will not add back in either - throwing the same SASL error.

We are looking at downgrading libvirt as I've seen that somewhere else - is
there another version of RH I should be trying? I have a host I can put it
on.

Hello all,

We recently had a network event where we lost access to our storage for a
period of time. The Cluster basically shut down all our VM's and in the
process we had three HV's that went offline and would not communicate
properly with the cluster.

We have since completely reinstalled CentOS on the hosts and attempted to
install them into the cluster with no joy. We've gotten to the point where
we generally get an error message in the web gui:


Which EL release and which oVirt release are you using? My guess would be
latest EL, with an older oVirt?
Y.

Can someone point me in the right direction to resolve this - it seems to
be a SASL issue perhaps?
