Dear List,
I have one last little problem with setting up an cluster. My gfs Mount will hang as soon as I do an iptables restart on one of the nodes..
Undoubtedly someone else with more experience with GFS will give you an answer, but to me this makes me think ip_conntrack stuff gets cleared out and sessions have to reestablish themselves.
Ray
Ray,
Thanks for your fast answer and getting me into the right direction. This sounds like a possible solution, but I have no clue how to fix it. I googled already a lot on ip_conntrack + gfs, but don't see a possible solution coming up.
Can someone/you please help me a little bit more with the issue?
Thanks a lot! Sven

You could allow traffic more broadly between your GFS-servers. Pro: packets will not depend on conntrack for delivery. Con: large hole in your firewall that you may not be able to live with.

Are your GFS mounts and your cluster on different sides of the firewall?
Maybe you can do something simple like a tunnel between the clusters and the mounts. Should be easier and safer than punching holes in the firewall. Or put a separate subnet or vlan just for the GFS traffic.
