How to prevent hosts entering emergency mode after upgrade from oVirt 4.4.1
Due to [Bug 1837864] – Host enter emergency mode after upgrading to latest build,
If you have your root file system on a multipath device on your hosts you should be aware that after upgrading from 4.4.1 to 4.4.10 you may get your host entering emergency mode.
In order to prevent this be sure to upgrade oVirt Engine first, then on your hosts:
- Remove the current lvm filter while still on 4.4.1, or in emergency mode (if rebooted).
- Reboot.
- Upgrade to 4.4.10 (redeploy in case of already being on 4.4.10).
- Run vdsm-tool config-lvm-filter to confirm there is a new filter in place.
- Only if not using oVirt Node:
- run “dracut –force –add multipath” to rebuild initramfs with the correct filter configuration
- Reboot.

Release Note
oVirt Engine
- BZ 2007286 Host is never fenced after a soft fence attemptPreviously, a non responsive host was first soft-fenced by the engine, but it didn’t fix the connectivity issue. The engine didn’t initiate a hard fence and the host was left in non responsive status.
In this release, Soft fencing has been fixed, and if the soft fencing does’t make the host responsive again, then the non-responding host treatment process continues correctly with the additional steps.
Enhancements
oVirt Engine
- BZ 1897114 Add additional logging information to be able to understand why host is stuck in Unassigned stateIn this release, monitoring of host refresh capabilities functionality was improved to help debug very rare production issues that sometimes caused the Red Hat Virtualization Manager to lose connectivity with the Red Hat Virtualization hosts.

Interessiert in verschiedenste IT Themen, schreibe ich in diesem Blog über Software, Hardware, Smart Home, Games und vieles mehr. Ich berichte z.B. über die Installation und Konfiguration von Software als auch von Problemen mit dieser. News sind ebenso spannend, sodass ich auch über Updates, Releases und Neuigkeiten aus der IT berichte. Letztendlich nutze ich Taste-of-IT als eigene Dokumentation und Anlaufstelle bei wiederkehrenden Themen. Ich hoffe ich kann dich ebenso informieren und bei Problemen eine schnelle Lösung anbieten. Wer meinen Aufwand unterstützen möchte, kann gerne eine Tasse oder Pod Kaffe per PayPal spenden – vielen Dank.
