[ovirt-users] Ovirt Node 4.1.1.1 installation, engine on gluster, existing disk sdb not found or filtered, deployment fails

Wed May 3 13:34:14 UTC 2017

Worked as described in the blog entry:

"The installer will ask if you want to configure your host and cluster for Gluster. Again, click "Next" to proceed. In some of my tests, the installer failed at this point, with an error message of Failed to execute stage 'Environment customization'. When I encountered this, I clicked "Restart Setup", repeated the above steps, and was able to proceed normally."

https://www.ovirt.org/blog/2017/04/up-and-running-with-ovirt-4-1-and-gluster-storage/

After a setup restart this error went away.

The last error i had was in the last stage of the setup process.

The installer was unable to connect to the engine vm after creation and timed out after about the 10th retry.
Postinstall failed, but the vm itself was up and running and i was able to ssh to it and to connect to the web ui.

Log attached.

Thx Oli

Hi,

     Can you provide me the exact question and your response to that because of which your setup failed ?

Thanks
