I set up a cluster of two servers CentOS 5.4 x86_64 with pacemaker
1.06 and corosync 1.1.2
I only installed the x86_64 packages (yum install pacemaker try to
install also the 32 bits one).
I configured a shared cluster IP (it's a public ip) and a cluster
website.
Everything work fine if i try to stop corosync on one of the two
servers (the services pass from one machine to the other without
problems), but if I reboot one server, when it returns alive it cannot
go online in the cluster.
I also noticed that there are several thread of corosync and if I kill
all of them and then I start again corosync, everything work fine again.
I don't know what is happening and I'm not able to reproduce the same
situation on some virtual servers!
Thanks,
Giovanni
the configuration of corosync is the following:
