How can i determine the donor node? Would that be seed node?

On the joiner you will see the following:

2016-11-08 12:13:57 140589576218368 [Note] WSREP: Member 1.0 (node2) requested state transfer from '*any*'. Selected 0.0 (node1)(SYNCED) as donor.

In my installation, I have used wsrep_node_name to assign names to the nodes.

Thank you

Can someone with better understanding of replication process explain the nature of this problem? Can it be caused by hostname resolution failure, or would it be storage related?

Therer is a possibility that something could have gone wrong on the donor node.

Checkout its error log to see whether that's the case.
