Persistence on oVirt-Nodes
by FERNANDO FREDIANI 11 Jan '18

11 Jan '18

Quick questions about Nodes (in order to not hijack the other thread). As they don't have much notion of persistence how can I: - To have a simple configuration backup in order for, if the Operating System disk fails I reinstall the Node, restore the config and everything comes back up fine ? Backing up /var /etc and /root folders would be enough or anything else ? - If I install something custom (e.g: A Zabbix Agent) it works until the host receives a new system/image Upgrade. Is there any way that can be made persistent ? - As oVirt-Nodes are images, if I install them in a SD Card or USB Stick will be there much write to disk still ? Other than possibly the logs and configuration changes what else could be written to disk ? If so a Feature Request to solve this would be to mount the logs partition in RAM as the Node boots and logrotate that. If someone needs to keep it more time can always use rsyslog Thanks Fernando

Non-RHEL RPMs gone after RHV-H upgrade
by Colin Coe 11 Jan '18

11 Jan '18

Hi all We're running RHV 4.1.6. Yesterday I upgraded the RHV-H nodes in our DEV environment to 20180102 and found that all the non-RHEL RPMs are now gone. Their associated config files in /etc are still there. The RPMs in question were from HPE SPP plus a monitoring system client (Xymon). I had thought that non-RHEL RPMs would persist after a host upgrade. Am I wrong on this? Thanks CC

oVirt Node 4.1 question, writing files to /root and RPMs
by Matt Simonsen 11 Jan '18

11 Jan '18

Hello all, I read at https://www.ovirt.org/develop/projects/node/troubleshooting/ that "Changes made from the command line are done at your own risk. Making changes has the potential to leave your system in an unusable state." It seems clear that RPMs should not be installed. Is this accurate for https://www.ovirt.org/node/ ? We have added smartctl and hpacucli in order to do disk and RAID monitoring. So far our node servers have retained changes across reboots, which is the primary reason I'm wondering if perhaps this applies to an older version of oVirt Node. If what we have been doing is not supported, what is the suggested method to do do hardware monitoring (in particular disks)? Thanks Matt

ovirt-live 4.2 - missing stable ISO? + Networking question - when to setup host & in NM or ifcfg?

Hosted Engine and network isolation
by Luca 'remix_tj' Lorenzetto 10 Jan '18

10 Jan '18

Hello, i just completed the setup of my 4.1 new cluster and i'm validating against a set of certification tests i did in the earlier version. One of the test was consisting on isolating the host where hosted-engine vm is running, setting ports on the switch down. Storage domain hosting the engine is FC. Up to 4.0.4, that was the version we was using during that tests, isolating the host was causing a restart of the engine vm on another available host with the fence of the isolated host. Now, with 4.1.8, isolating the host doesn't restart the engine on the other host, only moves the status of the host2 to EngineUnexpectedlyDown, while host1 is isolated, with the engine vm still running on it. Is this due to storage leases? What should be the right action to take in case of isolated host for moving engine away? Thank you, Luca -- "E' assurdo impiegare gli uomini di intelligenza eccellente per fare calcoli che potrebbero essere affidati a chiunque se si usassero delle macchine" Gottfried Wilhelm von Leibnitz, Filosofo e Matematico (1646-1716) "Internet è la più grande biblioteca del mondo.

Planned restart of production services
by Evgheni Dereveanchin 09 Jan '18

09 Jan '18

Hi everyone, I will be restarting several production systems within the following hour to apply security updates. The following services may be unreachable for some period of time: - resources.ovirt.org - package repositories - gerrit.ovirt.org - code review - jenkins.ovirt.org - CI master It will not be possible to submit/review patches, clone repositories or run CI jobs during this period. Package repositories will also be unreachable for a short period of time. I will announce you once the maintenance is complete. -- Regards, Evgheni Dereveanchin
