I've been having issues while attempting to begin BDR replication. If I set
up the main node, then use bdr_init_copy, it always fails on second node, as
shown below.
postgres$ rm -Rf $PGDATA
postgres$ echo db_password | pg_basebackup -X stream -h main_node_ip -p 5432
-U username -D $PGDATA
postgres$ cp $HOME/backup/postgresql.conf $PGDATA
postgres$ bdr_init_copy -U username -D $PGDATA
bdr_init_copy: starting...
Assigning new system identifier: 6098464173726284030...
Creating primary replication slots...
Creating restore point...
Could not connect to the remote server: could not connect to server: No such
file or directory
Is the server running locally and accepting
connections on Unix domain socket "/tmp/.s.PGSQL.5432"?
If I start both servers simply by using pg_ctl using conf set up for
replication, I get the following error on the main node:.
LOG: starting background worker process "bdr
(6098483684958107256,1,16384,): dr: apply"
CONTEXT: slot "bdr_16384_6098483684958107256_1_16384__", output plugin
"bdr", in the startup callback
ERROR: data stream ended
LOG: worker process: bdr (6098483684958107256,1,16384,): dr: apply (PID
6294) exited with exit code 1
. and, I get the following error on the second node:
ERROR: bdr output plugin: slot creation rejected, bdr.bdr_nodes entry for
local node (sysid=6098483778037269710, timelineid=1, dboid=16384):

It will keep cycling these errors indefinitely.
I have gotten this working off and on; but, I keep running into this issue.
I am on CentOS 6.5. Both servers can execute psql against the databases on
other nodes when not configured for replication, so it is not a connectivity
or firewall issue. I have installed using the beta2 rpm as well as built it
from source for rc1 (bdr stable).
Any ideas?
