Re: Live steraming replication setup issue!

I am using Postgres 9.4.

I removed /etc/Postgres/9.4/main directory from DR server and fetching data through below pg_basebackup command but no luck.

sudo -u postgres pg_basebackup -h <slave server ip> -D /var/lib/postgresql/9.4/main -U postgres -v –P

Do I need to enable these two parameters in slave server? archive_mode = on and archive_command = some command?

Biggest issue is, replication running between master and slave and I need to build DR from slave server.

Thanks,
Ashish

How do I setup replication between DR server and slave server while slave server and master server are running? I cannot stop master server. Can someone please guide with steps?

Steps are pretty much similar. You can setup replication between slave and DR by using the backup of Master database + WAL archives (if available) and setup primary_conninfo to point to slave database in recovery.conf on DR.
Can you please let us know which version of postgresql you are using ? Thats important for us to make any suggestions.
