Of course, three nodes are started up!
I am not sure what kind of cluster you used in your env, galera cluster
for mysql or MariaDB galera cluster? how did you configure and start the
galera cluster?
I set MariaDB galera cluster up successfully before. And here is my
understanding on the notes:
After installed and configured,
1. Start the first node with galera_new_cluster, but the left nodes use
service mysql start.
2. Turn on the firewall's ports accordingly on each node.
http://docs.openstack.org/ha-guide/shared-database-configure.html
For debug purpose, you can comment out the nodes in gcomm and change it
to be "wsrep_cluster_address=gcomm://", then try to start it and the
wsrep_cluster_size
should be 1 if successfully.

Hi,
In my environment I'm not able to bootstrap the cluster after a
crash and I thought it could be a configuration problem at cluster
level and I wanted to know if anybody has been able to configure it.
Thanks a lot.

Can you be more specific on why it wouldn't run "resiliently"?
I just saw you've asked question on codership group re.
bootstrapping the
cluster, is it related?
