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 <i class="moz-txt-slash"><span

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.

Hi all
I'm working on a Geo-replication setup that I'm having issues with.
Situation :

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
