Dear Gilberto,
If I am right, you ran into server-quorum if you startet a 2-node replica and shutdown one host.
From my perspective, its fine.
Please correct me if I am wrong here.
Regards,
Felix

Well I do not reboot the host. I shut down the host. Then after 15 min give up.Don't know why that happened.I will try it latter

Usually there is always only 1 "master" , but when you power off one of the 2 nodes - the geo rep should handle that and the second node should take the job.
How long did you wait after gluster1 has been rebooted ?

I was able to solve the issue restarting all servers.
Now I have another issue!
I just powered off the gluster01 server and then the geo-replication entered in faulty status.
I tried to stop and start the gluster geo-replication like that:
gluster volume geo-replication DATA root@gluster03::DATA-SLAVE resume Peer gluster01.home.local, which is a part of DATA volume, is down. Please bring up the peer and retry. geo-replication command failed
How can I have geo-replication with 2 master and 1 slave?
Thanks
