On 4.0 we have a new --upgrade-appliance feature on hosted-engine-setup: https://www.ovirt.org/develop/release-management/features/hosted-engine-migration-to-4-0/ The tool will ask you to take a backup pf your engine DB with engine-backup, then the tool will re-deploy a 4.0/el7 appliance automatically injecting there the backup of your 3.6 engine. The supported path is 3.6 -> 4.0 so you have also to do 3.5 -> 3.6 before that. >> Fedele >> >> Il giorno lun, 29/08/2016 alle 13.44 +0200, Fedele Stabile ha scritto: >>> ok, >>> I understand you suggest to upgrade centos 6.8 to 7.2 first >>> Correct? > > I misread your question - you seems to already run centos 6.8. > > I guess you are not using block storage (iSCSI/FC), do you? > > Nir > >>> >>> Il giorno lun, 29/08/2016 alle 14.38 +0300, Nir Soffer ha scritto: >>> > >>> > On Mon, Aug 29, 2016 at 2:15 PM, Fedele Stabile >>> > <fedele.stab...@fis.unical.it> wrote: >>> > > >>> > > >>> > > I would upgrade my CentOS 6.8 to 7 on my cluster of 5 ovirt nodes >>> > > (actually I'm running oVirt 3.5 and glusterfs 3.7). >>> > > Anyone has experienced troubles for this upgrade? >>> > >>> > Udev in 6.8 seems to be broken, breaking block storage. >>> > See https://access.redhat.com/solutions/2576511 >>> > >>> > I would avoid this upgrade, or test it on one hypervisor and report >>> > ovirt bug. >>> > >>> > Upgrading to 3.6 or 4.0 and centos 7.2 is recommended. >>> > >>> > Nir >>> > >>> >>> _______________________________________________ >>> Users mailing list >>> Users@ovirt.org >>> http://lists.ovirt.org/mailman/listinfo/users >>> >> _______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
