| Doc Text | Cause: Input and output packets are blocked (by netfilter firewall). Consequence: Corosync stuck and never creates membership. It's not possible to use cluster. Fix: Main problem was hidden in fact that corosync rely on multicast loop (packets sent to mcast group are returned back to sender). Sadly, this packets are filtered by netfilter, and if policy is block they are blocked and never arrive back to corosync. Solution is to use sockpair unix dgram socket, used only for local loopback. So packets are sent to multicast group AND to this unix dgram. Multicast group loopback is disabled but packets are always delivered thru this unix socket to localhost. Result: In given scenario, single node cluster is created. |
