Hi, Could you please let me know what does the error "system identifiers are same" mean? Below is the snapshot from one of the masters. I am setting up BDR as per the wiki http://wiki.postgresql.org/wiki/BDR_User_Guide#Initial_setup and source @ git://git.postgresql.org/git/users/andresfreund/postgres.git
irc1@ubuntuirc:~/bdr2/postgres-d6ed89e/postgres-bdr-bin/bin$ ./postgres -D ~/bdr2/postgres-d6ed89e/postgres-bdr-bin/bin/data2/ LOG: bgworkers, connection: dbname=testdb2 LOG: option: dbname, val: testdb2 LOG: registering background worker: bdr apply: ubuntuirc2 LOG: loaded library "bdr" LOG: database system was shut down at 2013-03-17 10:56:52 PDT LOG: doing logical startup from 0/17B6410 LOG: starting up replication identifier with ckpt at 0/17B6410 LOG: autovacuum launcher started LOG: starting background worker process "bdr apply: ubuntuirc2" LOG: database system is ready to accept connections LOG: bdr apply: ubuntuirc2 initialized on testdb2, remote dbname=testdb2 replication=true fallback_application_name=bdr FATAL: system identifiers must differ between the nodes DETAIL: Both system identifiers are 5856368744762683487. LOG: worker process: bdr apply: ubuntuirc2 (PID 16712) exited with exit code 1 ^CLOG: received fast shutdown request LOG: aborting any active transactions LOG: autovacuum launcher shutting down LOG: shutting down pgcontrol_data outputs different database system ids for the two nodes. So don't understand why it says identifiers are same. postgresql.conf content in one of the masters is like this- ///////////////// shared_preload_libraries = 'bdr' bdr.connections = 'ubuntuirc2' bdr.ubuntuirc2.dsn = 'dbname=testdb2' ///////////////// Two nodes are ubuntuirc and ubuntuirc2. Above is the output of the postgresql.conf from ubuntuirc. Any help on this will be appreciated. Thanks.
