Hi,
after a blackout one host of my ovirt not working properly. I tried to Reinstall it but ends with the following error "Failed to install Host ov1. Failed to execute stage 'Closing up': Failed to start service 'vdsmd'." I tried to start manually but it not start .
Now, I would like to reinstall from iso ovirt node.
After I put the host is in maintenance must I remove host from the cluster (Hosts -> host1 -> Remove) or I can reinstall without remove it?
If I remore it from the cluster the network configurations I lose them or not?
My ovirt version is oVirt Engine Version: 4.1.9.1-1.el7.centos.

Hi,
please note oVirt 4.1 is no longer supported. While waiting for 4.3 to be released I would suggest to use oVirt Node 4.2.8 to replace the failing node and start upgrading the remaining nodes and the engine as well. 
You should be able to reinstall the host without removing it from the cluster.
See https://ovirt.org/documentation/admin-guide/chap-Hosts.html#reinstalling-hosts for further information.

Thanks,
