Both yes. I've used omnipitr. Heavy logged.

Shipping for 0000000400004C4D00000090 was runned twice. But probably it is caused by me - I've tried to put file again in master pg_xlog from d0.XXX and run CHECKPOINT on master. But this didn't worked out. I have WAL files: d0:/usr/local/pgsql/core/wal # ls -laT 0000000400004C4D00000090 0000000400004C4D00000091 0000000400004C4D00000092 0000000400004C4D00000093 -rw------- 1 pgsql pgsql 16777216 May 21 20:36:33 2015 0000000400004C4D00000090 -rw------- 1 pgsql pgsql 16777216 May 21 21:28:51 2015 0000000400004C4D00000091 -rw------- 1 pgsql pgsql 16777216 May 21 21:28:52 2015 0000000400004C4D00000092 -rw------- 1 pgsql pgsql 16777216 May 21 21:30:05 2015 0000000400004C4D00000093 > Slave - if it does not find the WAL segment in master pg_xlog location, it > looks for the same in the location mentioned in the restore_command.

On slave, recovery.conf: In the time of writing it I switched from OmniPITR: restore_command = '/usr/local/pgsql/scripts/omnipitr/bin/omnipitr-restore --config-file /usr/local/pgsql/core/scripts/omnipitr/config/restore -sr "%f" "%p"' To: restore_command = 'cp /usr/local/pgsql/core/wal/%f %p' And manualy rsynced files from d0.XXX to /usr/local/pgsql/core/wal/ directory. >> What was wrong? > > > This error message can be ignored, did you try shipping > 0000000400004C4D00000093 to slave from master's archive location and see if > slave picked it up and applied ? As I wrote, I've only shipped up to 0000000400004C4D00000092. File 0000000400004C4D00000093 was archived after slave managed to start and successfuly start streaming WAL. But I've done this. When I've noticed that slave is OK - I stopped it, changed back to OmniPITR restore_command, and started again.
