Hi, 

Thank you for the answer and sorry for delay:

    1. What does the glustershd.log say on all 3 nodes when you run the
    command? Does it complain anything about these files?

No, glustershd.log is clean, no extra log after command on all 3 nodes

    2. Are these 12 files also present in the 3rd data brick?

I've checked right now: all files exists in all 3 nodes 

    3. Can you provide the output of `gluster volume info` for the this
    volume?

Volume Name: engine
Type: Replicate
Volume ID: d19c19e3-910d-437b-8ba7-4f2a23d17515

              Some extra info:

              We have recently changed the gluster from: 2 (full
                repliacated) + 1 arbiter to 3 full replicated cluster 

    Just curious, how did you do this? `remove-brick` of arbiter brick 
    followed by an `add-brick` to increase to replica-3?

Yes

#gluster volume remove-brick engine replica 2 node03:/gluster/data/brick force (OK!)

#gluster volume heal engine info (no entries!)

#gluster volume add-brick engine replica 3 node04:/gluster/engine/brick (OK!)

After some minutes

[root@node01 ~]#  gluster volume heal engine info
Brick node01:/gluster/engine/brick
Status: Connected
Number of entries: 0

Brick node02:/gluster/engine/brick
Status: Connected
Number of entries: 0

Brick node04:/gluster/engine/brick
Status: Connected
Number of entries: 0

    Thanks,

    Ravi

Another extra info (I don't know if this can be the problem): Five days ago A black out has suddenly shut down the networks switch (also gluster network) of node 03 and 04 ... But I don't know this problem is in place after this black out  

Thank you!
