reinstallation information
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-hos... for further information.

Hi Sandro, thanks for your reply and your council. You suggest me to upgrade my ovirt infrastructure. Can I upgrade the engine first and after the hosts and then can I reinstall using ovirt node 4.2.8 without remove it from engine? Thats right? I thought I could reinstall the hosts still in version 4.1 and upgrade later but I will follow your advice. Thank you for you help. nikkognt

Yes, you can start with the engine and then reinstall hosts one by one using oVirt Node 4.2.8. Once finished you can change cluster compatibility level to 4.2 for consuming new features included in 4.2.
I thought I could reinstall the hosts still in version 4.1 and upgrade later but I will follow your advice.
You can reinstall 4.1 hosts but 4.1 is not compatible with CentOS >= 7.5 so you'll miss all the security fixes from the past year including meltdown and spectre fixes. I would recommend to use 4.2.8.
Thank you for you help.

Thanks Sandro for your suggests. I followed your instructions and all work perfectly. The only problem that I found was the iso-domain that was not working properly then I have destroy it and I recreate it and now work. The question At the moment my hosts are installed with centos not ovirt-node. In the future I would like to reinstall them with ovirt-node iso. Is it possible? I only put in maintenance a then reinstall one by one with ovirt-node or I must remove from engine and then reinstall one by one? Many thanks Nikkognt

Hi Sandro, I tried to reinstall following instructions you told me... 1) I put in maintenance the host 2) I reinstall host with last version of ovirt node After that how can I add the host node in ovirt engine? From the engine? From host from terminal? Which command? How? When I try to reinstall from engine the following error appear "VDSM ov1 command Get Host Capabilities failed: General SSLEngine problem" To solve, I think that I remove the host node from the engine, reinstall from iso, and add the host reinstalled in the ovirt from engine. Do you think that I will lost the configuration of this host node? please help best regards nikkognt
