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 4.4.8 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 4.4.8 (redeploy in case of already being on 4.4.8).
  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.

Reason: The operation is executed frequently, causing the directory to grow extensively


Logs are rotated as follows:

  • host deploy, enroll certificates, host upgrade, ova, brick setup and db-manual logs are rotated monthly, and one archived file is kept.

  • check for updates is rotated daily, and one archived file is kept.

Compressed files are removed as follows:

  • host deploy, enroll certificates, host upgrade and ova logs are removed 30 days from when their metadata was changed.

  • check for updates is removed one day from its creation time.

  • brick setup log is removed 30 days from its creation time
