Обсуждение: Shutting down warm standby server? "

Hi people,

I've setup a warm standby reading WAL files, however when I try to
shut it down I get the message "server does not shut down".

Can someone help please, I presume it has something to do with the
server being busy waiting for the next WAL file? What is the correct
way to shut down a server reading WALs?

The command line output is below:

postgres@way5c:/mnt/archive$ /usr/local/pgsql/bin/pg_ctl stop -D
/data/postgres/ -m smart
waiting for server to shut
down...............................................................
failed
pg_ctl: server does not shut down


If I do a ps -ax:

 7956 pts/0    S      0:00 /usr/local/pgsql/bin/postgres -D
/data/postgres/
 7957 ?        Ss     0:10 postgres: startup process
 7371 ?        S      0:00 /bin/bash /data/postgres/restore.sh
/mnt/archive/000000010000001A000000A8 pg_xlog/RECOVERYXLOG
 1160 ?        S      0:00 sleep 1
 1161 pts/0    R+     0:00 ps -ax

it looks like it's waikting for the next WAL file.

Well, yeah, because you told it "-m smart" which is defined as "don't
exit until all work is done".  "-m fast" should work though, at least
in 8.2.x --- if you are using something older, try "-m immediate".

Aha.. excellent, thanks Tom!

Sorry, I shall try to RTFM in the future.
