Hello!

I'm seeing something strange. When executed a v heal info on my volume I
saw this:

***@gluster-gu3:~# gluster volume heal gv3 info
Brick gluster-gu3.xcade.net:/mnt/gv_gu3/brick
/
Status: Connected
Number of entries: 1

Brick gluster-gu1.xcade.net:/mnt/gv_gu3/brick
Status: Connected
Number of entries: 0

After running the heal command it still appears and the logs show:

[2018-11-22 14:15:57.008133] I [MSGID: 108026]
[afr-self-heal-entry.c:887:afr_selfheal_entry_do] 0-gv3-replicate-0:

And after running a full heal this appeared:

I'm running gluster 4.1.4 in Ubuntu Xenial. It is a replica 2 volume
with one brick in gluster-gu1 and one brick in gluster-gu3.
I was checking the .glusterfs directory and corroborated that for some
reason, in gluster-gu3 host it exists this file and not in gluster-gu1:

***@gluster-gu3:~# stat
/mnt/gv_gu3/brick/.glusterfs/indices/xattrop/00000000-0000-0000-0000-000000000001

  File:
'/mnt/gv_gu3/brick/.glusterfs/indices/xattrop/00000000-0000-0000-0000-000000000001'
  Size: 0             Blocks: 0          IO Block: 4096 regular empty file

 Birth: -

That indicates that the / needs to be healed in gluster-gu3 but is the
brick itself so I do not know how to proceed.

This is the volume info:

***@gluster-gu3:~# gluster volume info gv3

Volume Name: gv3
Type: Replicate
Volume ID: c5529e9f-2ded-4f56-9eff-f46f5b184d97
Status: Started
Snapshot Count: 0
Number of Bricks: 1 x 2 = 2
Transport-type: tcp
Bricks:
Brick1: gluster-gu3.xcade.net:/mnt/gv_gu3/brick
Brick2: gluster-gu1.xcade.net:/mnt/gv_gu3/brick
Options Reconfigured:
transport.address-family: inet
nfs.disable: on
performance.client-io-threads: off

Any help will be appreciated. Thanks!
