Description penguinpages 2021-01-01 14:44:56 UTC
Description of problem:
3 node HCI cluster CentOS8.  Converted to CentOS Streams now Engine no longer booting up.  All three nodes same with cycling events about python library error per below


Version-Release number of selected component (if applicable):


How reproducible:
100%


Steps to Reproduce:
1. Upgrade from CentOS8 to streams
2. Update packages.  Reboot
3. HCI with Gluster volumes are mounting but engine no longer starts

Actual results:

Something is wrong with update referencing gluster mount point for engine.


Just trying to start back up my VMs :)


I am about 90% certain nothing is wrong with the volumes.. Something patched and broke how HA starts engine services.

Comment 3 penguinpages 2021-01-12 21:01:02 UTC

Questions:

1) is their any way to manually start VMs while the "engine" is offline?
2) I think this ticket is noting a fix to be coming in 4.4+?

As noted ... I am on 4.4-2   I just need to start my VMs again.. and after three weeks now have to decide to give up debug and wipe because no ETA on fix.

Learning a bit more ..  I think root cause is package conflict issues
