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 :

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 at node01 ~]# sestatus*
*SELinux status:                 disabled*

*[root at node02 ~]# sestatus*
*SELinux status:                 disabled*

*[root at node04 ~]# sestatus*
*SELinux status:                 disabled*



Thank you
