See the difference between ovirt3 and other two nodes. LV 'rootvg01-lv02' in ovirt3 has only 224 GB of capacity. In replicated Gluster volume, storage capacity of the volume is limited by the smallest replica brick. If you want to have 1TB gluster volume then please make sure that all the bricks in the replicated volume has minimum 1TB capacity.
