[ovirt-users] Hosted Engine: brick size...is this a bug?

I have now done the oVirt 4.2.3.1 install at least 5 times, no, I don't consider myself any kind of expert. Even though the HE uses less than 10gb of space for some reason the install will fail if the brick is less than 58gb. Why is that? Look at this error: [ ERROR ] Error: Fault reason is "Operation Failed". Fault detail is "[Problem while trying to mount target]". HTTP response code is 400. [ ERROR ] fatal: [localhost]: FAILED! => {"changed": false, "msg": "Fault reason is \"Operation Failed\". Fault detail is \"[Problem while trying to mount target]\". HTTP response code is 400."} The size of the brick was set at 50gb: [lv1] action=create vgname=gluster_vg1 lvname=engine_lv lvtype=thick size=50GB mount=/gluster_bricks/engine Solution: Edit size to 60gb, re-run & voila, all is good. Is this a bug or maybe it's a problem with the way I'm doing things.
