Hi Dan,

During 1st rsync phase, the load balancer do not block any session to master DB.
And during 2nd rsync phase, the load balancer block all sessions to master DB 
in order to sync completely between master DB and target DB.

During 2nd rsync phase, load balancer can receive any sessions.
If you have more than 3 cluster DBs, the system can continue to provide service even in 2nd rsync phase.
All receiving queries are recorded in the replication server during 2nd rsync phase.
Those queries are executed to master DB and target DB after finished 2nd rsync.

>Start in recovery mode!

>1st recovery step of [global] directory...OK
>1st recovery step of [base] directory...OK
>1st recovery step of [pg_clog] directory...OK

Please check permission and owner of pg_xlog directory.
