Hi did a reinstall on the Host, and everything comes up again.

Than I put the Host in maintenance, reboot it, Confirm 'Host has been
Rebooted', Activate and the error comes up again: Gluster command
[<UNKNOWN>] failed on server

??

once the reboot happens and host comes up back, can you please check if
glusterd is running and operational?

On the gluster node (server)

Is not a replicate solution, only one gluster node

# gluster peer status
Number of Peers: 0

Strange. 

Thanks

Everything was running until I need to restart the node (host), after that I
was not ables to make the host active. This is the error message:

Gluster command [<UNKNOWN>] failed on server

I also disable JSON protocol, but no success

This error suggests gluster peer status is failing. It could be because of
selinux. I am just guessing. 

Can u run "/usr/sbin/gluster --mode=script peer status --xml" ? also try to
disable selinux if its active and check.

Regards,
Ramesh

Any idea?

Thanks

José
