hello everybody,
According to your last response only glusterfs is problematic on ovirt 4.1,
are there any other known problems on upgrading from 7.4 to 7.5 on the hosts?
known issues so far:
- upgrade on ppc64le has issues if libguestfs is installed due to a wrong dependency on
qemu-kvm-ma
- centos 7.5 repo dropped ovirt-4.1 and gluster-38 repos so they are not reachable unless
you manually change
http://mirror.centos.org/centos/7/
<
http://mirror.centos.org/centos/7/> to
http://mirror.centos.org/centos/7.4.1708/
<
http://mirror.centos.org/centos/7.4.1708/> for those repos.
- centos 7.5 has an outdated Virt SIG repo, as a workaround you can use test repo
instead:
https://buildlogs.centos.org/centos/7/virt/x86_64/ovirt-4.2/
<
https://buildlogs.centos.org/centos/7/virt/x86_64/ovirt-4.2/> ; this has been
already reported to centos release engineering team and they're working on fixing
this.
Also, if you happen to upgrade hosts from 4.1 to 4.2 and CentOS 7.4 to CentOS 7.5
(specifically libvirt 3.2 to 3.9) make sure that you have the host in Maintenance first
and there are no VMs running on the host during upgrade!
Neglecting to do so will result in corrupting your VM configuration and such VMs will no
longer start in future. There is no other fix than manually fixing the database
configuration for each VM or recreate them in GUI.
For each and every host update the host needs to be in Maintenance. Preferably use the GUI
to upgrade them.
Thanks,
michal
thank you for your efforts an the nice product!

FYI,
CentOS 7.5.1804 is now officially available. See announce here:

Users: I suggest to upgrade in order to get latest features, fixes and security fixes.
Just a note for ppc64le users, there's a known bug with libguestfs requiring
qemu-kvm-ma instead of qemu-kvm that may cause upgrade issues. This should be fixed in
next update which should land in CentOS in ~2 weeks.
If you are still on 4.1, please change your centos repos to point to
http://mirror.centos.org/centos/7.4.1708/
<
http://mirror.centos.org/centos/7.4.1708/> instead of
http://mirror.centos.org/centos/7 <
http://mirror.centos.org/centos/7>.
Then please update to latest 4.1 and then to oVirt 4.2 + CentOS 7.5 as soon as you can.
Devel: please cross check your jenkins jobs, especially those having to do something with
4.1 since CentOS 7.5 is not supporting oVirt 4.1 anymore. See above.
What is the issue with 4.1? it works on RHEL 7.5 so it sould work on CentOS 7.5.
ovirt-4.1 and gluster 3.8 are EOL so they've been removed from CentOS 7.5 not being
supported anymore.
Nir
Infra: please schedule a mass update of oVirt infrastructure to CentOS 7.5 + oVirt 4.2.3
ASAP.
Thanks,
