[Ocfs2-users] using 2 networks
As I understand, Ocfs2's heartbeat is disk-based. Ocfs2 also requires every node to be on the network. If a node disappears from the network, ocfs2 fences. What I'd like to find out is if you can put the nodes on 2 more more networks, say a private network, and configure such that ocfs2 will not fence a node as long as it is visible on 1 of the 2 (or more) networks? -------------- next part -------------- An HTML attachment was scrubbed...

Alexei... you've found new friends.. :-) Jokes apart, this is already in the OCFS2 wishlist but I don't know if the developers are already working on it.

It's well known problem and very long lasting request. Cluster system MUST have more than 1 heartbeat, esp. if it can self-fence. Temporary solutions - bonding, using loopback + ocpf routing (why not?) , etc - can't garantee normal work in some scenarios. Btw, new SLES10 promise to have OCFSv2 and heartbeat2 integrated (and heartbeat have normal, multi-interface heartbeat). ----- Original Message ----- From: Humpherys Philip D Contr 532 CMMXS/CL To: 'ocfs2-users@oss.oracle.com' Sent: Wednesday, October 25, 2006 1:13 PM Subject: [Ocfs2-users] using 2 networks As I understand, Ocfs2's heartbeat is disk-based.
