I forgot to mention in my previous mail that after starting mariadb in the first node I run:

mysql -u root --execute="SET GLOBAL wsrep_cluster_address='gcomm://';"

Don't do the above. Since you are starting the cluster with --wsrep_new_cluster, that's enough. I'm not sure of what it would do but I'd rather avoid to bootstrap the cluster two times.

If I don't, the cluster does not start at all, all I get is a disconnected cluster of size 0 on node #1, exactly as described here: https://mariadb.com/blog/mariadb-galera-cluster-quirk-bootstrapping

Yes, but this happens for a good reason and the manual is quite clear about that: You didn't set wsrep_cluster_address in your my.cnf. I would recommend to set it on all nodes, as it can cause all kinds of things to go wrong in the future (imagine you reboot your 1st node, it has no peers to reconnect to), plus some other side effects I cannot envision. So recommendation is really to have this set on all nodes with IP addresses of each node, in your case wsrep_cluster_address=gcomm://192.168.1.77 http://192.168.1.77/,192.168.1.80,[IP of node 3]

Got it, doing that :)

I tried setting wsrep_sst_method to mysqldump instead of rsync and it fails. Here are the error logs:

node #1: http://pastebin.com/UXr378mC

WSREP_SST: [ERROR] USER cannot be nil (19700101 00:05:06.%N) Try setting wsrep_sst_auth=user:pass - Nirbhay

node #2: http://pastebin.com/4xEi2ncS

node #3: http://pastebin.com/LWvmrdAt

Still investigating.
