Problem Percona Server cluster!

Hi,

I have a problem i use Percona-XtraDB-Cluster-server-5.5.23-23.5.333 on two nodes.

I make a test :
I create a database on the node1 and on the node2 i can see the new database it work.

I make a crash disk on the node1 and i create a new database on the node2 after i reboot the node1 and i start mysql the new database is not created on the node2.

If i create a new database on node1 or node2 the replication work but the second database is not wync on the node2.

is it normal and why the node2 is not sync on the node1.

how i can sync the both node please

thanks for your help

Good Day!
