Looks like I/O error on slave while doing keep_alive. We can get more useful info for the same from Slave log files.

In Slave nodes look for errors in /var/log/glusterfs/geo-replication-slaves/*.log and /var/log/glusterfs/geo-replication-slaves/*.gluster.log

I also noted that the second master gfs2 alternates between passive/faulty.
Not sure if this matters but, I have changed the /etc/hosts file to change
127.0.0.1 to gfs1 and so on because my node would not be in peer cluster
state.

One status row should show Active and other should show Passive. Please
provide logs from gfs1 and gfs2

Also please let us know,
1. Gluster version and OS
2. output of `ps aux | grep gsyncd` from Master nodes and Slave nodes

Hi all

I'm working on a Geo-replication setup that I'm having issues with.

Situation :

   - In the east region of AWS, I Created a replicated volume between 2
   nodes, lets call this volume *gvol*
   -
*In the west region of AWS, I Created another replicated volume between 2
   nodes, lets call this volume xvol *
   - Geo replication was created and started successfully

[root@gfs1 mnt]# gluster volume geo-replication gvol xfs1::xvol status

The data on nodes(gfs1 and gfs2) was not being replicated to xfs1 at all. I
tried restarting the services and it still didn't help. Looking at the log
files didn't help me much because I didn't know what I should be looking
for.

Can someone point me in the right direction?

Thanks
