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

[Oliver Dietzel]

Hi,

i try to set up a 3 node gluster based ovirt cluster, following this guide:
https://www.ovirt.org/blog/2017/04/up-and-running-with-ovirt-4-1-and-gluster-storage/

oVirt nodes were installed with all disks available in the system, installer limited to use only /dev/sda (both sda and sdb are HPE logical volumes on a p410 raid controller)


Glusterfs deployment fails in the last step before engine setup:

PLAY RECAP *********************************************************************

But: /dev/sdb exists on all hosts

[root at hv1 ~]# lsblk

What can i do to make this work?
