Hi Strahil,
Thank you for sharing your experience with reset-brick option.
Since he is using the gluster version 3.7.6, we do not have the reset-brick [1] option implemented there. It is introduced in 3.9.0. He has to go with replace-brick with the force option if he wants to use the same path & name for the new brick.
Yes, it is recommended to have the new brick to be of the same size as that of the other bricks.
Regards,
Karthik

I have used reset-brick - but I have just changed the brick layout.
You may give it a try, but I guess you need your new brick to have same amount of space (or more).
Maybe someone more experienced should share a more sound solution.
Best Regards,
