      Description

      My cluster crashed and i cannot restart the first node with galera_new_cluster.
      The nodes are distributed geographically in France with medium latency of 12ms.
      It remains on /usr/bin/galera_recovery without doing anything.

      This is my Galera config on all nodes (values may change in order to match node IP etc)...

      Since i've been using Galera for years in his MariaDB 10.x version i know that safe_to_bootstrap has to be set 1 ecc...But nothing works with galera_new_cluster and i cannot figure out why.

      This is a typical log from wsrep_recovery
