Hi Everyone,

In a test environment I'm trying to deploy a single node self hosted engine 4.4 
on CentOS 8 from a 4.3 backup. The actual setup is:
- node1 with CentOS7, oVirt 4.3 with a working SH engine. The data domain is a 
local NFS;
- node2 with CentOS8, where we are triyng to deploy the engine starting from 
the node1 engine backup
- host1, with CentOS78, running a couple of VMs (4.3)

I'm following the guide: 
https://www.ovirt.org/documentation/upgrade_guide/#Upgrading_the_Manager_to_4-4_4-3_SHE
Everything seems working fine, the engine on the node1 is in maintenance:global 
mode and the ovirt-engine service i stopped. The deploy on the node2 stucks in 
the following error:

For the "domain data" steps, I created the same folder "/data" on the node2 
server that should be used as NFS domain data (and, the playbook added 
correctly the storage):

          Please specify the storage you would like to use (glusterfs, iscsi, 
fc, nfs)[nfs]:
          Please specify the nfs version you would like to use (auto, v3, v4, 
v4_0, v4_1, v4_2)[auto]:
          Please specify the full shared storage connection path to use 
(example: host:/path): node2-server.tld:/data
          If needed, specify additional mount options for the connection to the 
hosted-engine storagedomain (example: rsize=32768,wsize=32768) []:
