Hello,
I have a single host test environment on 4.1.0 with hosted engine VM.
I'm going to update to 4.1.1.
Normally the workflow was:
- put env in global maintenance
- update engine part with engine-setup and such
- update other os related packages of hosted engine VM
- shutdown hosted engine vm
- exit global maintenance
Verify engine VM starts and all is ok form web admin gui.
These steps above I have already done and now my engine vm has latest
4.1.1 setup.
Now I want to proceed also with the only existing host part and I have
already run:
- shutdown all running VMs
- put env in global maintenance
- shutdown hosted engine vm
Status is:
[root@ractor ~]# hosted-engine --vm-status
!! Cluster is in GLOBAL MAINTENANCE mode !!
--== Host 1 status ==--
conf_on_shared_storage : True
Status up-to-date : True
Hostname : ractor.mydomain

Normally I set host into local maintenance now, but I receive this error:
[root@ractor ~]# hosted-engine --set-maintenance --mode=local
Unable to enter local maintenance mode: there are no available hosts
capable of running the engine VM.
[root@ractor ~]#
[root@ractor ~]# ps -ef|grep [k]vm
root 887 2 0 Feb14 ? 00:00:00 [kvm-irqfd-clean]
[root@ractor ~]#
Is this a bug or changed functionality?
Yes in the past it was possible, now it's explicitly prevented since the
engine VM couldn't be migrated or restart somewhere else:
