Good that is ok for you now.
As Gianluca told you the command to see all the gluster volume settings is : gluster
volume get vol_name all
The previous command you used : gluster volume info vol_name will list only modified
settings from default and not all the settings. The output shows only volume "Options
Reconfigured".
Regarding if this is an important bug that affects gluster 7.6(or other versions) and
should be disabled by default, i dont know for sure.
I am just using ovirt as a hyperconvergence tool.
Maybe someone from the ovirt development team can answer that.
