Hey,
as said in another part of this thread Node can be updated through oVirt Engine. But you can also update an existing Node by booting the newer image using PXE, USB or ISO to update an installed Node.
Greetings fabian
Hi, If i install the oVirt node software to a server with a SSD disk, where do I have to deploy the new version on the engine so that I can upgrade the node?
Just to summarize and put this all in one place: There are 2 general methods for upgrading an ovirt-node installation. 1. Through oVirt Engine 2. Through oVirt Node installation media (ISO, CD, USB, PXE) #1 is done by installing the ovirt-node-iso rpm on oVirt Engine. A node is then placed in maintenance mode, and you trigger the upgrade from the engine interface. #2 is done using installation media. Simply boot your host running an old version of node from new media. Either PXE, CDROM, USB, SD card, ISO, etc. are supported. Once you boot from the media, it will bring you to a TUI screen where you choose upgrade. That will upgrade and leave existing configuration in place. There are some other options as well, but they're in a slightly different, but related, category. Reinstall: This will wipe out any existing configuration and install from scratch This is done either by choosing the "Reinstall" option in the Boot menus (with CD/USB/SD Card) or adding "reinstall" to the kernel command line (any method). Uninstall: This will wipe the ovirt-node-iso installation from the disk entirely and reboot. Again, there is a "Uninstall" option in the boot menu. You can also add "uninstall" to the kernel command line. Mike
