[Gluster-users] Problem adding replicated bricks on FreeBSD

I'm trying to debug an issue that I've found while attempting to qualify
GlusterFS for potential distributed storage projects on the FreeBSD-11.1
server platform - using the existing package of GlusterFS v3.11.1_4
The main issue I've encountered is that I cannot add new bricks while
setting/increasing the replica count.
If I create a replicated volume "poc" on two hosts, say s1:/gluster/1/poc
and s2:/gluster/1/poc, the volume is created properly and shows replicated
status, files are written to both volumes.
If I create a single volume: s1:/gluster/1/poc as a single / distributed
brick, and then try to run
gluster volume add-brick poc replica 2 s2:/gluster/1/poc
it will always fail (sometimes after a pause, sometimes not.) The only
error I'm seeing on the server hosting the new brick, aside from the
generic "Unable to add bricks" message, is like so:
I [MSGID: 106578]
replica-count is set 2
I [MSGID: 106578]
type is set 2, need to change it
E [MSGID: 106054]
Failed to set extended attribute trusted.add-brick : Operation not
supported [Operation not supported]
E [MSGID: 106074] [glusterd-brick-ops.c:2565:glusterd_op_add_brick]
0-glusterd: Unable to add bricks
E [MSGID: 106123] [glusterd-mgmt.c:311:gd_mgmt_v3_commit_fn] 0-management:
Add-brick commit failed.
I was initially using ZFS and noted that ZFS on FreeBSD does not support
xattr, so I reverted to using UFS as the storage type for the brick, and
still encounter this behavior.
I also recompiled the port (again, GlusterFS v3.11.1) with the patch from
https://bugzilla.redhat.com/show_bug.cgi?id=1484246 as this deals
specifically with xattr handling in FreeBSD.
To recap - I'm able to create any type of volume (2 or 3-way replicated or
distributed), but I'm unable to add replicated bricks to a volume.
I was, however, able to add a second distributed brick ( gluster volume
add-brick poc s2:/gluster/1/poc ) - so the issue seems specific to adding
and/or changing the replica count while adding a new brick.
Please let me know if there are any other issues in addition to bug
#1452961 I should be aware of, or additional log or debug info I can
