I’m not sure what’s the use case. But if you are taking the base backup with default format you need to make sure all tablespace directories should be empty as it tries to create backup file under it. So try with tar format and make sure -D directory is empty then it will create all tablespace backups in that directory with <<tablespace our>>.tar and you should be good.
While doing PITR or setting HA server you need to create table space directory on target server and copy the corresponding tar file and untar it. You will get tablespace directory information from tablespace_map file from backup.
Hi,
Need help with replication setup, pg_basebackup failing with:
pg_basebackup -P -R -X stream -c fast -h <node_name> -U <user_name> -p <port#> -D <dat_location> -v
Password:
pg_basebackup: initiating base backup, waiting for checkpoint to complete
pg_basebackup: checkpoint completed
pg_basebackup: write-ahead log start point: 6/67000028 on timeline 2
pg_basebackup: starting background WAL receiver
pg_basebackup: created temporary replication slot "pg_basebackup_3720137"
pg_basebackup: error: could not create directory "……": File exists
It's explicitly telling you the problem: a file already exists in the replicated $PGDATA.
pg_basebackup: removing contents of data directory "…………"
pg_basebackup: changes to tablespace directories will not be undone
-- Death to America, and butter sauce.
Iraq lobster!
