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

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 *
ovirt-4.0-dependencies.repo:[ovirt-4.0-epel]
ovirt-4.0-dependencies.repo:#baseurl=http://download.fedoraproject.org/pub/epel/7/$basearch

ovirt-4.0-dependencies.repo:baseurl=http://copr-be.cloud.fedoraproject.org/results/patternfly/patternfly1/epel-7-$basearch/

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

these are the ovirt-repos files with the excludepkgs line added

I add also the part of log on the manager relatives to host-deploy where the error is logged

[root@ovcmgr host-deploy]# more ovirt-host-deploy-20170825092719-xxxxxx-53018ceb.log  | grep collectd

After this i see that there is and include package for epel-release, that will install the epel repository,

so i installed manually the epel-repository

added the excludepkgs line but now the error is Package collectd-disk cannot be found

this is the epel.repo modified

[root@ovc2n05 yum.repos.d]# more /etc/yum.repos.d/epel.repo

the epel-testing.repo has all disabled

This is the part of log on the manager

I don't know what other to try.

Any help would be accepted
