Re: pg_basebackup: could not get write-ahead log end position fromserver: ERROR

Hi,

1) have you configured the archive_command to a script that archives the online WAL to the archive destination and deletes the file?

2) As far as I know the cleanup of archive destination has to done manually. 

Regards,

Nawaz

Dear Team,

 

1)Whilst taking full backup via pg_basebackup I have facing below error. Backup is schedule via cronjob.

 

================================================================================

****** Full Backup of posgresql database started Fri Jun 8 20:40:36 PKT 2018.

080618204036

pg_basebackup: initiating base backup, waiting for checkpoint to complete

pg_basebackup: checkpoint completed

pg_basebackup: write-ahead log start point: 43/400252F8 on timeline 1

17624153/17624153 kB (100%), 2/2 tablespaces                                        

pg_basebackup: could not get write-ahead log end position from server: ERROR:  requested WAL segment 000000010000004300000040 has already been removed

pg_basebackup: removing data directory "/db01/pgdata/hot_backup/080618204036"

 

 

 

 

2)Also after complete backup I have to manually delete the wal archive files using pg_archivecleanup. Is there any way to automatically delete after full backup is complete and wal archive are no longer required.

 

pg_archivecleanup -d /db01/wal_archive 00000001000000390000000A

 

 

Kindly let me know how to rectify.

 

pg_basebackup -z -X fetch --progress -v --format=t -D /db01/pgdata/hot_backup/$DD --no-password
