[Gluster-users] One node goes offline, the other node can't see the replicated volume anymore

[Joe Julian]

Huh.. this was in my sent folder... let's try again.

There's something missing from this picture. The logs show that the 
client is connecting to both servers, but it only shows the 
disconnection from one and claims that it's not connected to any bricks 
after that.

Here's the data I'd like to have you generate:

unmount the clients
gluster volume set firewall-scripts diagnostics.client-log-level DEBUG
gluster volume set firewall-scripts diagnostics.brick-log-level DEBUG
systemctl stop glusterd.service
truncate the client, glusterd, and server logs
systemctl start glusterd
mount /firewall-scripts
Do your iptables disconnect
telnet $this_host_ip 24007 # report whether or not it establishes a 
connection
ls /firewall-scripts
wait 42 seconds
ls /firewall-scripts
Remove the iptables rule
ls /firewall-scripts
tar up the logs and email them to me.

You can reset the log-level:

gluster volume reset firewall-scripts diagnostics.client-log-level
gluster volume reset firewall-scripts diagnostics.brick-log-level

lastly, do you have a loopback interface (lo) on 127.0.0.1 and is 
localhost defined in /etc/hosts?
