Hi all, I'm setting up a simple two node cluster over a shared storage. I want to use gfs, but I'm hitting some problems much earlier. After setting up the basics with system-config-cluster and starting up ccsd, cman and rgmanager on both nodes, clustat says on node1: Member Status: Quorate Member Name Status ------ ---- ------ node1 Online, Local, rgmanager node2 Offline Service Name Owner (Last) State ------- ---- ----- ------ ----- http_test node1 started and on node2: Member Status: Quorate Member Name Status ------ ---- ------ node1 Offline node2 Online, Local, rgmanager Service Name Owner (Last) State ------- ---- ----- ------ ----- http_test node2 started For some reason nodes don't see eachother, which results in the above situation. I guess the same reason causes fence_tool join -w to wait forever, which on boot appears as a hung machine (a bit ugly, because fenced is started before sshd by default). Both nodes have their info in /etc/hosts as well as in DNS and network connectivity is OK. As the documentation is not much helpful with how to figure this out, I'm asking it here: what minimal requirements must be met for two machines to see eachother? How to debug a situation like this? -- Jure Pečar http://jure.pecar.org/ -- Linux-cluster@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/linux-cluster
