[Gluster-users] gluster peer probe failing

[Guy Cukierman]

Thanks, but my current settings are:
net.ipv4.ip_local_reserved_ports = 30000-32767
net.ipv4.ip_local_port_range = 32768    60999
meaning the reserved ports are already in the short int range, so maybe I misunderstood something? or is it a different issue?

https://review.gluster.org/#/c/17494/ will it and the next update of 3.10 should have this fix.


If sysctl net.ipv4.ip_local_reserved_ports has any value > short int range then this would be a problem with the current version.
Would you be able to reset the reserved ports temporarily to get this going?

Hi,
I have a gluster (version 3.10.2) server running on a 3 node (centos7) cluster.
Firewalld and SELinux are disabled, and I see I can telnet from each node to the other on port 24007.

When I try to create the first peering by running on node1 the command:
gluster peer probe <node2 ip address>

I get the error:
“Connection failed. Please check if gluster daemon is operational.”

And Glusterd.log shows:

And a file is create under /var/lib/glusterd/peers/<node2 ip address> which contains:
uuid=00000000-0000-0000-0000-000000000000
state=0
hostname1=192.168.1.17

and the glusterd daemon exits and I cannot restart it until I delete this file from the peers folder.

Any idea what is wrong?
thanks!
