Hi there!

Yep, it's correct: 

It looks like You have a set up A (Master) ---> B (Replica) ---> C Replica (Base backup from Replica B)

Master (A): 192.168.100.1

Slave1 (B): 192.168.100.2

Slave2 (C): 192.168.100.3

My recovery.conf in slave2(C) is:

restore_command = 'exec nice -n 19 ionice -c 2 -n 7 ../../bin/restore_wal_segment.bash "../wal_archive/%f" "%p"'
archive_cleanup_command = 'exec nice -n 19 ionice -c 2 -n 7 ../../bin/pg_archivecleaup_mv.bash -d "../wal_archive" "%r"'
recovery_target_timeline = 'latest'
standby_mode = on
primary_conninfo = 'host=192.168.100.2 port=5432 user=replicator application_name=replication_slave02'

So, seems to be right to me... Is that u mean?

Thanks

Sure... Here's the total information:

recovery.conf:

Can you post the contents of your recovery.conf file, suitably
anonymised if necessary?

Hi Lucas,

I followed your question I generated the same error:

cp: cannot stat `/pgdata/arch/00000003.history': No such file or directory

2016-01-09 14:11:42 IST FATAL:  timeline 1 of the primary does not

match recovery target timeline 2

It looks like You have a set up A (Master) ---> B (Replica) ---> C Replica (Base backup from Replica B)

It seems you have used recovery.conf (to replicate from master to slave) to new replica setup C and there is high probability not changing the primary connection info

in C's recovery.conf (Replica B's Connection info)

During testing providing B's connection info in C's recovery.conf resolved the issue.

Please verify the Primary connection info parameter in recovery.conf (C replica) might resolve your problem.

Thanks and regards,
