Re: [ovirt-users] Procedure to upgrade single-host datacenter from el6 to el7

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.

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 -- Rik Theys System Engineer KU Leuven - Dept.
