It's impossible to say without knowing your configuration. Please share
the cluster.conf (only obfuscate passwords, please) along with the log
files. The more detail, the better. Versions, distros, network config, etc.
Uninstalling corosync is not likely help. RGManager is something fairly
high up in the stack, so it's not likely the cause either.
Did you configure the timeouts to be very high, by chance? I'm finding
it difficult to fathom how the node can withdraw without being fenced,
short of cleanly stopping the cluster stack. I suspect there is
something important not being said, which the configuration information,
versions and logs will hopefully expose.
