After restored hosted engine as a new vms, all the existing & live hosts and storage domain are showing offline
Hi Team due to some reasons one of our slef hosted engine went down, hence we provisioned new centos vm and restored the hosted engine backup file. After restoring we could see all the Datacenter, cluster, storage, hosts and vm entities in restored ovirt engine but they all are offline. please help us how to we connect all the running hosts and storage domain, vms back to restored hosted engine. do we need to get a down time for all the vms to restore the hosts? how do I activate all the existing storage domains as is.

Could you please check the logs (engine as well as vdsm logs on the hosts) why the storage domains are offline and post relevant parts here? Thanks Vojta
I seen the hosted engine ssl expired hence unbale to connect with all the hosts. openssl x509 -noout -enddate -in /etc/pki/ovirt-engine/certs/engine.cer notAfter=Dec 22 15:08:50 2021 G VDSM cal2-app3-nodeb.wac..net command Get Host Capabilities failed: PKIX path validation failed: java.security.cert.CertPathValidatorException: validity check failed The original setup was done with self hosted engine but since had a issues I provisioned new standalone HE and restored the backup from original setup. now the problem is when i try to renew the hosted engine ssl with engine-setup option it is throwing error stating hosted engine vm not set with Global maintenance mode as below Stage: Setup validation During execution engine service will be stopped (OK, Cancel) [OK]: [ ERROR ] It seems that you are running your engine inside of the hosted-engine VM and are not in "Global Maintenance" mode. In that case you should put the system into the "Global Maintenance" mode before running engine-setup, or the hosted-engine HA agent might kill the machine, which might corrupt your data. [ ERROR ] Failed to execute stage 'Setup validation': Hosted Engine setup detected, but Global Maintenance is not set. [ INFO ] Stage: Clean up Log file is located at /var/log/ovirt-engine/setup/ovirt-engine-setup-20220111013444-ojwb6y.log [ INFO ] Generating answer file '/var/lib/ovirt-engine/setup/answers/20220111013625-setup.conf' [ INFO ] Stage: Pre-termination [ INFO ] Stage: Termination [ ERROR ] Execution of setup failed Is there any way I can overcome this issue.. how do I skip this global maintenance mode validation as im running the new HS in standalone mode?
even we brought up the self hosted engine in one of the host but when we try to renew the expired ssl using engine-setup option, it is throwing same error. we did put the system to global maintenance mode from one of the host Stage: Setup validation During execution engine service will be stopped (OK, Cancel) [OK]: [ ERROR ] It seems that you are running your engine inside of the hosted-engine VM and are not in "Global Maintenance" mode.

According to https://access.redhat.com/solutions/3028811 after v 3.5.4 the engine-setup can update the certificates on the engine. Once you got them renewed and if the hosts' certificates haven't expired -> communication should be recovered . I According https://access.redhat.com/solutions/3532921 the recommended way to regenerate the hosts' certificates is to set the host into maintenance from the UI and then either via the 'Enroll Certificate' (from the Hosts page) or remove & add the host. Can you provide a short summary like version of engine & hosts? Also, you can login on a Hypervisor (Host) and use 'hosted-engine --set-maintenance --mode=global' to set the Global HA. To verify: 'hosted-engine --vm-status'. This will allow you to run the engine-setup (run it from tmux or screen session). P.S.: Those solutions can be accessed via developer subscription (in case you don't have a RH one). Just check developers.redhat.com.

Hi Strahil Nikolov, I am from Ramesh team. Kindly find below the manage engine & hosts version. oVirt Open Virtualization Manager : 4.4.3.12-1.el8 Host: OS Version: RHEL - 8 - 2.2004.0.2.el8 OS Description:oVirt Node 4.4.3
Have you executed 'hosted-engine --set-maintenance --mode=global' on a host that us supposed to run the HostedEngine VM ?
