Re: [Linux-cluster] node fails to join cluster after it was fenced



Hi

The "IPtable" service is not running on both nodes.
We are thinking in update the platform (RHE4 U4 RHCS 4U4) but thid is not easy right now because we have several servers on production. Another reason to not do it the version update is that we are waiting for an update 5 por RHE4 or the production release for RHE5. In this moment we only update "rgmanager" in some sites (we have several issues with the rgmanager of update 2 RHCS4).

Thanks again for you reply.

Best regards,

Luis G.

Hi

we have the same problem... :|   we have RHE4 U2 with cluster suite 4
U2, in our case one node send a fenced to the other node, and we have
not succes to rejoining the node to cluster.
On logs appeared that node 2 cannot comunicate with node 1, but the
network connectivity is working fine
In a test we deleted the cluster.conf from node 2 and reboot it. After
the reboot the node got the last version of cluster.conf from node 1,
but still cannot joining to cluster again.

Below of this mail, we attached a little dump from node 1 that were the
cluster service is running.

That's showing the same symptoms. The new node is sending joinreq messages but
they are not received by the node that's already in the cluster.

If you're running U2 you should upgrade anyway. there are lots of bugs fixed
between that and the current U4.
