I see that bricks are mounted in /gluster/brick3 and that is the
reason it does not show anything in "Brick Directory" drop down
filed. If bricks are mounted under /gluster_bricks then it would
have detected automatically. There is an RFE which is raised to
detect bricks which are created manually.<br>

No, you do not need to change anything for the new volume. But if
you plan to enable o-direct on the volume then you will have to
disable/turn off remote-dio.<br>
