Hello, I'm testing my PITR recovery procedures and something doesn't look right. The following is from the logs upon starting postgres with recovery.conf file in place 2007-03-23 05:56:00 MDTLOG: database system was interrupted at 2007-03-18 05:09:15 MDT @ 2007-03-23 05:56:00 MDTLOG: starting archive recovery @ 2007-03-23 05:56:00 MDTLOG: restore_command = "cp /data/pgLocal/archive/WAL_restore/%f "%p"" cp: cannot stat `/data/pgLocal/archive/WAL_restore/00000001.history': No such file or directory @ 2007-03-23 05:56:00 MDTLOG: restored log file "000000010000011A000000EE.004E0060.backup" from archive @ 2007-03-23 05:56:00 MDTLOG: restored log file "000000010000011A000000EE" from archive @ 2007-03-23 05:56:00 MDTLOG: checkpoint record is at 11A/EE4E0060 @ 2007-03-23 05:56:00 MDTLOG: redo record is at 11A/EE4E0060; undo record is at 0/0; shutdown FALSE @ 2007-03-23 05:56:00 MDTLOG: next transaction ID: 2415965426; next OID: 81701223 @ 2007-03-23 05:56:00 MDTLOG: next MultiXactId: 43380; next MultiXactOffset: 92368 @ 2007-03-23 05:56:00 MDTLOG: automatic recovery in progress @ 2007-03-23 05:56:01 MDTLOG: redo starts at 11A/EE4E00B0 @ 2007-03-23 05:56:15 MDTLOG: restored log file "000000010000011A000000EF" from archive @ 2007-03-23 05:56:27 MDTLOG: restored log file "000000010000011A000000F0" from archive @ 2007-03-23 05:56:31 MDTLOG: restored log file "000000010000011A000000F1" from archive @ 2007-03-23 05:56:34 MDTLOG: restored log file "000000010000011A000000F2" from archive @ 2007-03-23 05:56:40 MDTLOG: restored log file "000000010000011A000000F3" from archive @ 2007-03-23 05:56:50 MDTLOG: restored log file "000000010000011A000000F4" from archive @ 2007-03-23 05:57:02 MDTLOG: restored log file "000000010000011A000000F5" from archive @ 2007-03-23 05:57:07 MDTLOG: restored log file "000000010000011A000000F6" from archive @ 2007-03-23 05:57:11 MDTLOG: restored log file "000000010000011A000000F7" from archive @ 2007-03-23 05:57:14 MDTLOG: restored log file "000000010000011A000000F8" from archive @ 2007-03-23 05:57:18 MDTLOG: restored log file "000000010000011A000000F9" from archive @ 2007-03-23 05:57:21 MDTLOG: restored log file "000000010000011A000000FA" from archive @ 2007-03-23 05:57:27 MDTLOG: restored log file "000000010000011A000000FB" from archive @ 2007-03-23 05:57:29 MDTLOG: restored log file "000000010000011A000000FC" from archive @ 2007-03-23 05:57:33 MDTLOG: restored log file "000000010000011A000000FD" from archive @ 2007-03-23 05:57:35 MDTLOG: incorrect resource manager data checksum in record at 11A/FD492B20 @ 2007-03-23 05:57:35 MDTLOG: redo done at 11A/FD492210 @ 2007-03-23 05:57:36 MDTLOG: restored log file "000000010000011A000000FD" from archive @ 2007-03-23 05:57:36 MDTLOG: archive recovery complete @ 2007-03-23 05:57:36 MDTLOG: could not truncate directory "pg_multixact/members": apparent wraparound @ 2007-03-23 05:59:00 MDTLOG: database system is ready @ 2007-03-23 05:59:00 MDTLOG: transaction ID wrap limit is 3065701724, limited by database "postgres" @ 2007-03-23 12:14:04 MDTLOG: autovacuum: processing database "postgres" My concern is that there were many more logfiles to be played following "00000010000011A000000FD" (ie 000000010000011E0000005C) yet it appears the recovery stop at that point and called it good. I would assume all WAL logs would be restored. The recovery.conf was simple: restore_command = 'cp /data/pgLocal/archive/WAL_restore/%f "%p"' The backup file 000000010000011A000000EE.004E0060.backup" contained: START WAL LOCATION: 11A/EE4E0060 (file 000000010000011A000000EE) STOP WAL LOCATION: 11A/EFF68AB8 (file 000000010000011A000000EF) CHECKPOINT LOCATION: 11A/EE4E0060 START TIME: 2007-03-17 20:29:16 MDT LABEL: 076_pgdata.tar STOP TIME: 2007-03-18 05:16:17 MDT Does the line: incorrect resource manager data checksum in record at 11A/FD492B20 mean there is a corrupted WAL log file? Any insight here would be helpful version PG 8.1.2 64 bit Linux thanks Warren Little Chief Technology Officer Meridias Capital Inc ph 866.369.7763 |
