[ovirt-users] Problem installing hyperconverged setup

Hi, I am currently setting up an Ovirt cluster in a test environment and cannot get the hyperconverged setup to run properly. I have installed 3 nodes on version 4.2.8. I keep getting the following error - TASK [Create LVs with specified size for the VGs] ****************************** failed: [node01.ovirt.local] (item={u'lv': u'gluster_thinpool_sdb', u'size': u'1005GB', u'extent': u'100%FREE', u'vg': u'gluster_vg_sdb'}) => {"changed": false, "item": {"extent": "100%FREE", "lv": "gluster_thinpool_sdb", "size": "1005GB", "vg": "gluster_vg_sdb"}, "msg": " WARNING: Pool zeroing and 3.00 MiB large chunk size slows down thin provisioning.\n WARNING: Consider disabling zeroing (-Zn) or using smaller chunk size (<512.00 KiB).\n Volume group \"gluster_vg_sdb\" has insufficient free space (157261 extents): 343040 required.\n", "rc": 5} to retry, use: --limit @/tmp/tmpbXqHhw/lvcreate.retry All 3 nodes have an /sdb installed which are different sizes but all in excess of 450Gb. I have specified JBOD in the setup. I have tried reducing the size of the engine, data and vmstore bricks to 50Gb each instead of the default but the installation still fails. I think it has something to do with the thin provisioning but not sure what. Any help would be much appreciated. Thanks Paul.
