Hello, i can't find the documentation on howto recover from a single host OS disk failure in a 3 node HCI cluster. I already searched the ovirt, RHV and RHHI documentation but i can't find the corresponding documentation. So can anyone please give me some hints? In our dev lab i have 3 servers with 2 disks each. sda for ovirt node and sdb for gluster. Let's assume the disk sda of a single node is defunct and needs to be replaced. So i grab a new disk and reinstall ovirt node from PXE. After the installation is finished i would like to reinstall the host from ovirt admin portal, but that doesn't work because of an invalid fingerprint. So how can i re-add that host to ovirt and gluster? Kind regards, Timo
