I recopied the authorized keys from the engine host, did restorecon -RFv /root, and chmod
644 on .ssh. I’ll try it again.

I think all you need on the inaccessible host is
/root/.ssh/authorized_keys
copied from a working host (with the same ownership, permissions and SELinux context)

I recopied the authorized keys and ssh keys from engine host to it and copied it's
keys back.
What do I need to look at to prevent this in the future?

Maybe an issuewith sudo? It should be installing as root, right?

When I try the reinstall it fails with this in events on the web
interface:
Host kvm01 installation failed. SSH authentication to
'root(a)kvm01.digitaldatatechs.com <mailto:root@kvm01.digitaldatatechs.com> '
failed. Please verify provided
credentials. Make sure key is authorized at host.
I can ssh into the host from the engine host with no password and no
problem.
I will dig deeper until I hear from you.
Thanks.

Hi Eric,
Can you try the following:
1. Set the node in maintenance
2. From the Hosts section -> Installation -> Reinstall 3. Fill in if
the host is hosting the HostedEngine and the rest of the wizard 4.
Start the install 5. If it succeeds -> remove the maintenance
Best Regards,
Strahil Nikolov
