[ovirt-users] Re: Cluster stuck in maintenance - Hosts not upgrading as expected

2021-05-24 Thread Strahil Nikolov via Users 
Hi David,

you can always prohibit root and also make an exclusion for specific hosts 
(like oVirt's Engine).

Maybe something like :

Match Address 192.168.2.5
PermitRootLogin yes

Thank you, Ritesh.
Those logs were perfect, and I immediately found the problem.

This was my fault.
I had disabled Root Login in /etc/ssh/sshd_config (because let's face it, we 
all can agree that logging in as root over ssh is normally a bad idea!)

I just updated that from "no" to "prohibit-password" and restarted sshd.
I'll report back if I still have problems after this.

2021-05-23 Thread Ritesh Chikatwar 
Hello,


Can you check at which task the upgrade has struck. Please share the
relevant log at the time.


To check at which tasks it failed  ssh to ovirt engine and navigate to
directory /var/log/ovirt-engine/host-deploy/ and also share the vdsm logs
from host as well.

[ovirt-users] Re: Cluster stuck in maintenance - Hosts not upgrading as expected

2021-05-22 Thread Edward Berger 
I'm saw something similar on a test cluster on CentOS 8.3.
You can take it out of global maintenance mode by navigating the engine UI
to edit cluster -> scheduling policy and turn off global maintenance there.

Not sure what else is going on.  It wants me to put all three hosts into
maintenance mode which is impossible.
