Hi guys,
I got a slave server running Postgres 9.2 with streaming replication and wal_archive in an EC2 Instance at Amazon.
Postgres logs are showing me this error:
restored log file "000000020000179A000000F8" from archive
invalid record length at 179A/F8FFF3D0
WAL segment `/var/lib/pgsql/9.2/archive/00000003.history` not found
streaming replication successfully connected to primary
FATAL: could not receive data from WAL stream: FATAL: requested WAL segment 000000020000179A000000F8 has already been removed
However, 000000020000179A000000F8 file is inside /var/lib/pgsql/9.2/archive directory:
postgres@devops:/var/lib/pgsql/9.2/archive$ ls -la | grep 000000020000179A000000F8
-rw------- 1 postgres postgres 16777216 Sep 16 05:16 000000020000179A000000F8
It's an UBUNTU instance, so my recovery.conf is:
/etc/postgresql/9.2/main/recovery.conf:
restore_command = 'exec /var/lib/pgsql/bin/restore_wal_segment.bash "/var/lib/pgsql/9.2/wal_archive/%f" "%p"'
archive_cleanup_command = '/var/lib/postgresql/bin/pg_archivecleaup_mv.bash'
recovery_target_timeline = 'latest'
standby_mode = on
primary_conninfo = 'host=IP_MY_SLAVE port=5432 user=replicator application_name=devops'
What can be happening, if the file is in there?
Thanks
Patrick
