Nope, the database is empty (I just created it with mysql_install_db; also all nodes are fresh installs). Only the first node has SYNCED in its log indeed: # grep SYNCED buildroot.err 700101 0:01:10 [Note] WSREP: Shifting JOINED -> SYNCED (TO: 0)

The two others show neither SYNCED or any reference to mysql.sock.

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

...

Does this mean that mariadb tries to sync nodes but for some reason the script hangs, the nodes are never sync and remain unusable?

I'm afraid that must be something along those lines. I have the following suspicions:

* SELinux or Apparmor not disabled, causing the SST to hang forever. * Ports not open on the firewall (for the record you need 3306, but also 4444, 4567 and 4568).

Ok, I'm following this lead. I'll let you know.
