Could you check if the self-heal daemon on all nodes is connected to the 3 bricks? You will need to check the glustershd.log for that.
If it is not connected, try restarting the shd using `gluster volume start engine force`, then launch the heal command like you did earlier and see if heals happen.

I've executed the command on all 3 nodes (Know is enougth only one) , after that the "heal" command report elements between 6 and 10 ... (sometime 6, sometime 8, sometime 10)

Log on glustershd.log don't say anything :

If it doesn't, please provide the getfattr outputs of the 12 files from all 3 nodes using `getfattr -d -m . -e hex /gluster/engine/brick/path-to-file` ?

hum.... Is selinux the problem? but on node04 was disabled (AFTER GLUSTER JOIN, I hope to remember) ... You think I needs to relabel? how?

[root@node01 ~]# sestatus
SELinux status: disabled

[root@node02 ~]# sestatus
SELinux status: disabled

[root@node04 ~]# sestatus
SELinux status: disabled

Thank you

Thanks,
Ravi

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

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!
