Обсуждение: Error while setting up streaming replication, postgres 9.0-beta 4
Hello everyone,
OS = Linux Suse, sles 11, 64-bit
Postgres version = 9.0 beta-4
I'm trying to test streaming replication. I set up a primary and secondary. The primary starts normal, but when I start the standby, it doesn't start up. The log looks like this:
LOG: database system was interrupted while in recovery at log time 2010-08-23 13:30:43 EDT
HINT: If this has occurred more than once some data might be corrupted and you might need to choose an earlier recovery target.
LOG: entering standby mode
WARNING: WAL was generated with wal_level=minimal, data may be missing
HINT: This happens if you temporarily set wal_level=minimal without taking a new base backup.
FATAL: hot standby is not possible because wal_level was not set to "hot_standby" on the master server
HINT: Either set wal_level to "hot_standby" on the master, or turn off hot_standby here.
LOG: startup process (PID 5875) exited with exit code 1
LOG: aborting startup due to startup process failure
Note that I have checked multiple times that 'wal_level' is set to 'hot_standby' on the primary, and the secondary has correct connection information to the primary in 'resolve.conf'.
Any pointers?
Thanks.

The WARNING above indicates that the backup was taken with an inadequate wal_level setting. regards, tom lane
Great! I made the base backup again as you said, and its working now.
Thanks.
Thanks.

indicates that the backup was taken with an inadequate wal_level
setting.
