Description Nag Pavan Chilakam 2015-10-14 09:18:53 UTC

If I try to peer probe another gluster node, "I am getting Probe returned with Transport endpoint is not connected" error.
Only when i flush iptables using iptables -F  on both the nodes, I am able to peer nodes.

Comment 1 Anand Nekkunti 2015-10-14 18:10:47 UTC

This is expected behavior , you need to provide proper iptable rules or flush iptable rules.

Comment 2 Soumya Koduri 2015-11-03 13:59:02 UTC

Anand,

Could you please close the bug in case if this is expected behaviour.

Comment 3 Anand Nekkunti 2015-11-04 06:17:46 UTC

This is expected behavior , you need to provide proper iptable rules or flush iptable rules for <=3.7.5 release  and firewall service file is available from next release 3.7.6, you can attach this service file(glusterfs.xml)  to your active zone to open ports which are required for glusterfs,
