I tried several ways to upgrade a node and the hosted-engine and it didn´t

when you add the Ovirt/CentOS repositories, dnf starts to throw a bunch of 
conflicts and it doesn´t work anymore, and you have just bricked your host.

Reinstall a node is easy. The problem is reinstall a node with GlusterFS hyper

For the hosted-engine, the only option would be reinstall it and restore a 
backup, right?
I wrote a summary, when I reinstalled my home cluster (AFAIK I changed 
from CentOS 7 to 8 in the meanwhile)

It would be really nice if the Leapp 
(https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/9/html/upgrading_from_rhel_8_to_rhel_9/index)
 was available for CentOS and Rocky.

For the engine itself, be sure to take a backup then I would consider to
re-install the host and restore the backup.

For the node I would put the host in maintenance and remove it from the
cluster, reinstall it with 9.1 and add it to the cluster.

If you decide to attempt an in-place upgrade let us know how it goes.
