Thanks so much!  Yes, that patch fixed the “out of sync network” issue.  However, we’re still unable to join a fully updated 9.4 host to the cluster - now with "Failed to connect Host to Storage Servers”.  Downgrading all of the updated packages fixes the issue.

Please see the attached vdsm.log and supervdsm.log from the host after updating it to EL 9.4 and then trying to activate it.  Any more suggestions would be greatly appreciated.

Thanks again,
Devin
