Comment 3 for bug 1251342

In general it is IMHO a very bad idea to use different data or log paths on different nodes. Cluster should be formed from homogeneous nodes in all aspects.

With rsync SST method, even if both nodes have the same datadir and innodb_data_home_dir paths, the SST fails. So the problem here is datadir != innodb_data_home_dir.
With wsrep_sst_method=xtrabackup-v2 this is no problem though.

This is the configuration I used on nodes.
