[pgpool-general: 2483] Re: Help error code e1012 on pgpool II 3.3.0 while clicking Recovery button

[Syed Irfan]

This is what the recovery.conf looks like.
*******************************************
#recovery_target_timeline = 'latest'
standby_mode          = 'on'
primary_conninfo      = 'host=postgres-p.rolta.com port=5432 user=postgres'
trigger_file = '/var/log/pgpool/trigger/trigger_file1'
********************************************************



The basebackup.sh on both postgres databases is as follows
**************************************************

#/bin/sh -x
#
# XXX We assume master and recovery host uses the same port number
PORT=5432
master_node_host_name=`hostname`
master_db_cluster=$1
recovery_node_host_name=$2
recovery_db_cluster=$3
tmp=/tmp/mytemp$$
trap "rm -f $tmp" 0 1 2 3 15

psql -p $PORT -c "SELECT pg_start_backup('Streaming Replication', true)" postgres

rsync -C -a -c --delete --exclude postgresql.conf --exclude postmaster.pid \
--exclude postmaster.opts --exclude pg_log \
--exclude recovery.conf --exclude recovery.done \
--exclude pg_xlog \
$master_db_cluster/ $recovery_node_host_name:$recovery_db_cluster

ssh -T $recovery_node_host_name mkdir $recovery_db_cluster/pg_xlog
ssh -T $recovery_node_host_name chmod 700 $recovery_db_cluster/pg_xlog
ssh -T $recovery_node_host_name rm -f $recovery_db_cluster/recovery.done

cat > $tmp <<EOF
#recovery_target_timeline = 'latest'
standby_mode          = 'on'
primary_conninfo      = 'host=$master_node_host_name port=$PORT user=postgres'
trigger_file = '/var/log/pgpool/trigger/trigger_file1'
EOF

scp $tmp $recovery_node_host_name:$recovery_db_cluster/recovery.conf

psql -p $PORT -c "SELECT pg_stop_backup()" postgres

This is usually caused by postgres trying to replay WAL files from the wrong source.  Did you clean out the pg_xlog directory on the replica before taking the base backup?

What does your recovery.conf look like?
