Hi Rik. The flow should work, as long as the OS is supported by oVirt. However, you will still need to move it to a new cluster. On Fri, Apr 22, 2016 at 3:44 PM, Rik Theys <Rik.Theys@esat.kuleuven.be> wrote:
Hi,
I'm looking for the best procedure to upgrade a host from CentOS 6 to CentOS 7. The host is the only host in the oVirt data center (the engine is running on another machine and manages multiple data centers).
For datacenters with multiple hosts I followed the following steps: - Add new cluster - Put host in maintenance - Remove host from old cluster - Reinstall host - Add host to new cluster - repeat for all hosts until old cluster is empty
This worked OK and the data center was never "non operational".
Is the procedure identical for a data center with only one host?
Should I also remove the host from the (only) cluster in the data center, or should I reinstall it and select the "reinstall" option in the oVirt web interface? Since there is only one host in the cluster there's no need to create a new cluster?
Is there any state on the host that I should keep when performing the reinstall with CentOS 7?
The host is using FC storage (local disks configured as FC through multipath).
Regards,
Rik
