I just started node1 as donor with ‘/etc/init.d/mysql start --wsrep-new-cluster’. Then started second node. and check "show status like 'wsrep%'" in mysql. but the second’s wsrep_local_index became 0 and first node became 1.
Also started third node and now first node became 2 and third node became 0.
Why donor node changed? I can’t understand. please help me.
