Hi Miguel, are you also using Gluster ? If yes, it makes the things more complicated.If you use iSCSI, NFS or SAN you will be able to remove the host from engine  and then you can swap the OS disks, reinstall and add it backBest Regards,Strahil Nikolov On Tue, Mar 16, 2021 at 21:08, miguel.garcia@toshibagcs.com<miguel.garcia@toshibagcs.com> wrote: We have a cluster with one master and 3 ovirt-nodes and the master server got the hard disk fried however the vms are still running and working in shape. We have concerns if restore master by reinstall OS and restore from latest ovirt backup would be enough or if we had to resintall ovirt cluster from scratch along with each node. Thanks in advance for your input. _______________________________________________ Users mailing list -- users@ovirt.org To unsubscribe send an email to users-leave@ovirt.org Privacy Statement: https://www.ovirt.org/privacy-policy.html oVirt Code of Conduct: https://www.ovirt.org/community/about/community-guidelines/ List Archives: https://lists.ovirt.org/archives/list/users@ovirt.org/message/E3R6TRVLP2ODEW...
