Re: [ovirt-users] Centos 7.3 ovirt 4.0.6 Can't add host to cluster collectd or collectd-disk not found - SOLVED - BUG

[Claudio Soprano]

No one answered to my messages, so i don't know if someone replicated 
the bug or not in CentOS 7.3.

Let me know if you need more info.

More investigation on this for you :)

the bug is only on CentOS v7.3 infact on previous hosts with CentOS < 
v7.3 i have no problem about the name of the network.

I discovered also that i don't need only to rename the network name, 
but also the vnic profile associated, infact with network name def, 
and vnic profile default, it still didn't work, renamed network name 
and vnic profile to def both, now works on CentOS v7.3 with no errors 
also from GUI.

when i create a network both network name and vnic profile are called 
the same (for my it was default).

Hope that my info can help you.

Another boring issues is that i need to detach the network to all the 
hosts to rename only, but also to change the network on all VMs that 
use it also if they are stopped, i was lucky only 2 VMs and only 4 
hosts, but i can't imagine people have 40-50 hosts and maybe 100-200 
VMs on a network.

Anyway now i have Centos V7.3 and V7.2 hosts both working.

Ok i SOLVED the problem, but i don't know if it is a BUG, the problem 
is the name default, but i had it working with ovirt v3 and v4.0pre 
for sure.

I don't know if the check has been added in the setup_host_network or 
not.

This is that i did

i manually added a ifcfg-def and ifcfg-enp12s0.1 file (first for the 
bridge and the second for the VLAN) to an host that don't have VLAN 1

[root@XXXXX network-scripts]# more ifcfg-enp12s0.1
# Generated by VDSM version 4.19.28-1.el7.centos
DEVICE=enp12s0.1
VLAN=yes
BRIDGE=def
ONBOOT=yes
MTU=1500
DEFROUTE=no
NM_CONTROLLED=no
IPV6INIT=no

[root@XXXXX network-scripts]# more ifcfg-def
# Generated by VDSM version 4.19.28-1.el7.centos
DEVICE=def
TYPE=Bridge
DELAY=0
STP=off
ONBOOT=yes
MTU=1500
DEFROUTE=no
NM_CONTROLLED=no
IPV6INIT=no

then run

systemctl restart network

it didn't give errors, and ip addr shows

[root@XXXXX network-scripts]# ip addr

I will try to change the name of that network to something different 
from default

The problem is not the host-deploy, infact the deploy finished 
without errors, if i remember good in the deploy process the network 
are not set, i need to attach each network i need manually, under 
hosts, network interface, setup host networks

and the problem is there, when i attach all the VLANs (including the 
default, that is VLAN 1) it gave error, default is not present in 
the system, if i add all the VLANS (excluding the default, that is 
VLAN 1) it is OK, but the host will not activate because missing the 
default vlan.

If i manually add the 2 configuration files (ifcfg-default and 
ifcfg-intX.1) to the host and make a systemctl network restart, it 
gave error then

ip addr reports

the vlan 1 is added, but not the Bridge to default (the default is 
missing error).

I don't know if the name "default" (for the network, VLAN 1) could 
be the problem, but i can't rename now, because i need to detach 
from the hosts, but actually i can't.

I added 3 screenshoots to show you the situation, before adding VLAN 
1 ("default" network), the error when adding it, and the info on the 
error.

    Ok in this way i could install the hosts, but we got another
    error on them when setup networks

    we have on each hosts 2 interfaces

    interface 1 is ovirtmgm

    interface 2 is a TRUNK with VLANs inside.

    All my old hosts are all the VLANs on interface2 included VLAN
    1 (tagged).

    When i setup networks for the new hosts 4.0.6 i can't include
    VLAN 1, ovirt answer with

    VDSM hostname.domainname command HostSetupNetworksVDS failed:
    [Errno 19] default (that is VLAN 1) is not present in the system.

    So thinking about upgrading to 4.1.5 we updated all the new
    hosts (the old are still v4.0.6) and reinstall from beginning
    but still we get the same error.

    What means that error ?


Adding Marcin and Dan about this.

        Hi all,

        we are installing new nodes on a Ovirt 4.0.6 Cluster, the
        new nodes were installed from a Minimal 1707 iso image,
        Centos v7.3.1611


    Any reason for keeping 4.0.6 hosts? oVirt 4.0 has reached End
    Of Life back in January[1]
    And you can install 4.1 hosts in 4.0 cluster compatibility mode.

    That said, you may want to "yum
    install centos-release-opstools" which should provide you the
    missing collectd packages by providing the same repos already
    included in ovirt-release41 rpm.

    [1]
    http://lists.ovirt.org/pipermail/announce/2017-January/000308.html
    <http://lists.ovirt.org/pipermail/announce/2017-January/000308.html>


        in the log of host-deploy (on the manager) it indicates
        that collectd packages was not found.

        I found this bug in the ovirt 4.1.0 version where it tells
        to disable the EPEL repository, in another tread on redhat
        someone told to add

        excludepkgs=collectd*

        always in the epel repository

        I checked all my repository and i found epel reference
        only in

        [root@xxxx yum.repos.d]# grep epel *

        so before includespkgs i added the excludepkgs line

        removed the host, reinserted and still again collectd not
        found

        so i added the excludepkgs line in all the ovirt sections

        removed the host, reinserted and still again collectd not
        found

        I removed on the manager also the file
        /var/cache/ovirt-engine/ovirt-host-deploy.tar but still
        the same error
