These were my error logs. but it turns out Line 4 of var-log-mysql-error2.log was the hint I needed to get this working. /server/mysql/data/wsrep_recovery.lBRkgo could not be created because galera could not write to that directory

This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed, 
something is definitely wrong and this may fail.
Please help us make Percona XtraDB Cluster better by reporting any
bugs at https://bugs.launchpad.net/percona-xtradb-cluster
key_buffer_size=0
read_buffer_size=131072
max_used_connections=0
max_threads=153
thread_count=0
connection_count=0
It is possible that mysqld could use up to 
key_buffer_size + (read_buffer_size + sort_buffer_size)*max_threads = 60961 K  bytes of memory
Hope that's ok; if not, decrease some variables in the equation.
