oVirt Node 4.4.2 is now generally available

The oVirt project is pleased to announce the general availability of oVirt Node 4.4.2 , as of September 25th, 2020.

This release completes the oVirt 4.4.2 release published on September 17th

Important notes before you install / upgrade

Please note that oVirt 4.4 only supports clusters and data centers with compatibility version 4.2 and above. If clusters or data centers are running with an older compatibility version, you need to upgrade them to at least 4.2 (4.3 is recommended).

Please note that in RHEL 8 / CentOS 8 several devices that worked on EL7 are no longer supported.

For example, the megaraid_sas driver is removed. If you use Enterprise Linux 8 hosts you can try to provide the necessary drivers for the deprecated hardware using the DUD method (See the users’ mailing list thread on this at https://lists.ovirt.org/archives/list/users@ovirt.org/thread/NDSVUZSESOXEFJNPHOXUH4HOOWRIRSB4/ )

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 4.4.2 you may get your host entering emergency mode.

In order to prevent this be sure to upgrade oVirt Engine first, then on your hosts:

1. Remove the current lvm filter while still on 4.4.1, or in emergency mode (if rebooted).

2. Reboot.

3. Upgrade to 4.4.2 (redeploy in case of already being on 4.4.2).

4. Run vdsm-tool config-lvm-filter to confirm there is a new filter in place.

5. Only if not using oVirt Node:
   - run "dracut --force --add multipath” to rebuild initramfs with the correct filter configuration

6. Reboot.
