Hi
When I tried to take a base backup of the master database I go the following message:
$ pg_basebackup.exe -U sns84 -h 192.168.56.10 -D ccslave
pg_basebackup: directory "/usr/local/pgsql/master/pg_tblspc" exists but is not empty
Any I idea how I can fix it - please help

To my knowledge of the topic the pg_tblspc directory should be empty
unless you create a tablespace yourself using CREATE TABLESPACE
command. The directory then stores the symbolic link to the
user-created tablespace which points to a location specified in above
mentioned command. The names of the files inside the folder are
consistent with namespaces' OIDs. I would assume that the tablespace
file that is stored in your pg_tblspc folder making it 'present and
not empty' is the file connected to the tablespace which was the topic
of this whole discussion. Check the folder to verify my assumption.
Hope this helps
Cheers
Hi
Thanks for your quick response, new tablespaces were indeed created in that folder in the master database but why it should now prevent me from taking a basebackup to setup another slave ?
Thanks

After moving the content to Desktop I was able to perform pg_basebackup. Ok just took a quick look at pg_basebackup.c file it appears that it recreates all directories including those being set as location for tablespace files (referred by the folder in pg_tblspc folder in your data directory) I would try pointing the bakup to another drive so pg_basebakup will be able to create all needed folders without a problem of them already existing.
