--- Comment #10 from Daniel Morante <daniel at morante.net> ---
The quick fix for this problem is to make sure you have procfs mounted as per
https://www.freebsd.org/doc/en_US.ISO8859-1/articles/linux-users/procfs.html

After doing so, it shows the brick as online.  This was tested on Gluster 7.6
and probably works for 8.0 (https://reviews.freebsd.org/D25037)

Task Status of Volume replicated
------------------------------------------------------------------------------
There are no active volume tasks

The core of the problem appears to be in the "gf_is_pid_running" function in 
https://github.com/gluster/glusterfs/blob/v7.6/libglusterfs/src/common-utils.c#L4098

It needs to be patched with a FreeBSD equivalent that doesn't use "proc"
