[ovirt-users] Internal Engine Error while adding a new (distribute glusterfs) Storage Domain

Hello, I created (through oVirt web) a GlusterFS distributed volume with four bricks. When I try to add a New Domain - GlusterFS Data I am getting Error while executing action Add Storage Connection: Internal Engine Error and Error validating master storage domain: ('MD read error',) Full logs engine.log - https://paste.kde.org/pefcwndgc/zamd2o/raw vdsm.log - https://paste.kde.org/pxf91znwq/6mhrg3/raw Gluster info/options - https://paste.kde.org/pjfauvisg/grfrvj/raw (oVirt3.6/Centos7) ps: My installation seems to work only with replica-3 oVirt Optimized volumes. Every other combination fails with the error above. Any help would be appreciated. Thanks, K.
