Depending on your SST mechanism Node 1 may be able to serve data after some initialization. i.e only mariabackup (aka xtrabackup equivalent) per https://galeracluster.com/library/documentation/sst.html out of the built in SST mechanisms.

Glad to see you have a 3-node cluster. I hope the last node isn't arbitrator.

Thank you for the answer. The last node is not arbitrator. I always start the clustering from the Node 1 with the command "galera_new_cluster". What is the danger to make the Node 3 arbitrator in my system?
