Thanks for looking.

[GENERAL] Issues trying to run bdr_init_copy with new setup

[Jorge Torralba]

Just started playing with BDR. Originally setup the environment on two
separate servers as per the quick start guid and used the sql commands to
add nodes. Moving on to command line, I am running into some issues.

I am sure I am just overlooking something really simple. But, on the
primary node I created two databases and created two groups. one within
each database. No issues so far. However, now on the 2nd node, I want to
add it to the cluster using bdr_init_copy. It partially works but then it
dies as you can see below.

/var/lib/pgsql/9.4-bdr/data

-bash-4.1$ rm -rf *

-bash-4.1$ bdr_init_copy -D /var/lib/pgsql/9.4-bdr/data -n node2 -d
'host=10.5.101.176 port=5432' --local-dbname='host=10.5.101.179 port=5432'
