Hi folks, we're snapshotting at san level, two volumes containing a postgres 9.1.5 database, and pg_xlog respectively. This database cluster is a streaming replicant. We're stopping the database completely, taking the snapshots, restarting the database. I export these snapshots as luns to a VM, mount the disks in the VM, cp -a the database and pg_xlog contents to a staging area. Start postgres using -D /staging/9.1/main. Postgres fails to start. >From log: 2012-09-25 12:41:30.147 CDT,,,9597,,5061ecca.257d,1,,2012-09-25 12:41:30 CDT,,0,LOG,00000,"database system was interrupted while in recovery at 2012-09-25 12:18:06 CDT",,"This probably means that some data is corrupted and you will have to use the last backup for recovery.",,,,,,,"" 2012-09-25 12:41:30.155 CDT,,,9597,,5061ecca.257d,2,,2012-09-25 12:41:30 CDT,,0,LOG,00000,"starting archive recovery",,,,,,,,,"" 2012-09-25 12:41:30.354 CDT,,,9597,,5061ecca.257d,3,,2012-09-25 12:41:30 CDT,,0,LOG,00000,"restored log file ""000000010000074D000000EE"" from archive",,,,,,,,,"" 2012-09-25 12:41:30.529 CDT,,,9597,,5061ecca.257d,4,,2012-09-25 12:41:30 CDT,,0,LOG,00000,"restored log file ""000000010000074D000000E2"" from archive",,,,,,,,,"" 2012-09-25 12:41:30.529 CDT,,,9597,,5061ecca.257d,5,,2012-09-25 12:41:30 CDT,,0,PANIC,XX000,"unexpected pageaddr 74D/7C000000 in log file 1869, segment 226, offset 0",,,,,,,,,"" 2012-09-25 12:41:30.530 CDT,,,9595,,5061ecc8.257b,1,,2012-09-25 12:41:28 CDT,,0,LOG,00000,"startup process (PID 9597) was terminated by signal 6: Aborted",,,,,,,,,"" 2012-09-25 12:41:30.530 CDT,,,9595,,5061ecc8.257b,2,,2012-09-25 12:41:28 CDT,,0,LOG,00000,"terminating any other active server processes",,,,,,,,,"" /staging/9.1/main/recovery.conf: restore_command = 'cp /staging/9.1/main/pg_xlog/%f "%p"' Does the PANIC shown in above log entry indicate a corrupt WAL file? -- Sent via pgsql-admin mailing list (pgsql-admin@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
