hi, it works well. I have create the lvm partitions like the onode01 and I have added the bricks from onode02 and onode03. after that t have add the hosts into ovirt and and it works well to.
but to add the nodes I have to remove the ovirt yum repos from /etc/yum.repo.d because then he will not try to download a newer version. but I have now only one open point. the volumes with three bricks are there but only the hosted engine domain is there. the iso and vmstore domain was not there. strange. I think it was available on the single note but I try to reinstall all three servers again to be sure that it's works. thanks . br marcel Am 29.
