I haven't tried the POXIS compliant domain but from what I recall and remember happening, I couldn't bind a host to more then a single storage domain. I could be wrong but I couldn't select more then a single storage domain a host could be associated with. So it was either Local storage or GlusterFS storage, but both couldn't be bound to a single host. Does oVirt have the facilities to test this out to see how it should be done?

Let's take this scenario, assume gluster is working perfectly: HOST01 4TB Local LUN /dev/sdb 4TB Gluster FS (brick w/ host02,03) /dev/sdc HOST02 4TB Local LUN /dev/sdb 4TB Gluster FS (brick w/ host01,03) /dev/sdc HOST03 4TB Local LUN /dev/sdb 4TB Gluster FS (brick w/ host02,01) /dev/sdc For each host I need the local LUN to be available for VM's with the GlusterFS storage that's distributed across all three nodes. However, when I tried to add a local LUN, the host was removed from the storage domain rendering it unavailable. Now when I took out the local LUN, I was able to readd that host to the GlusterFS storage domain. So it appears I can't add a local LUN when a host is already participating in a GlusterFS storage domain.

Hi Dominik, I think I found it - it seems that for some reason my gateway is missing in 'ip route'. Running 'ifdown ovirtmgmt; ifup ovirtmgmt' fixes it, which proves that network scripts read properly the ifcfg-ovirtmgmt file. Do you have any idea where to look for?

I think I have a theory about ovirt1 , but I have to test it. 1. Ovirt1 has a team device controlled by NetworkManager , but in engine those interfaces are unused 2. I guess that when I recently 'reinstalled' the host from UI, the old teamports' ifcfg- was moved to ifcfg--1 and the original file was left empty. 3. When the system rebooted, network.service rereads all ifcfg-* files and starts the team0 , but when NetworkManager reads the empty files - he alters the /etc/resolv.conf which leads to out-of-sync status. Still, this is only theory and as ovirt3 has no team device (plain gluster arbiter) - I'm not sure how close is this one.
