Thread: Archive WAL Logs Failed

Archive WAL Logs Failed

From
"Subbiah, Stalin"
Date:

Hi All,

Yesterday, we'd archiver problems in copying archived wal files from pg_xlog to archive destination at the end of full hotbackup. Below are the errors from server logs.

What makes me to wonder is that why does archiver tries to copy "000000010000000800000074.0066C9C0.backup" again when it's already been archived. As soon I removed "000000010000000800000074.0066C9C0.backup" from archive location, then archiver was happy to copy again and moved on to archiving 000000010000000800000074 etc.

2006-11-07 00:35:23 CST  LOG:  archived transaction log file "000000010000000800000074.0066C9C0.backup"
2006-11-07 00:35:23 CST  LOG:  archive command "test ! -f /b01/pgdata/archive/db1/000000010000000800000074.0066C9C0.backup && cp pg_xlog/000000010000000800000074.0066C9C0.backup /b01/pgdata/archive/db1/000000010000000800000074.0066C9C0.backup" failed: return code 256

Any idea what may be going on here.

Thanks,
Stalin

Nope. Only archiver does that.

Since we had this problem the backups are running just fine and no
problems whatsoever with archiver either. Strange!!!

This was a bug fixed in 8.1.5

http://archives.postgresql.org/pgsql-committers/2006-06/msg00305.php

I notice it isn't mentioned in the 8.1.5 release notes. You should
upgrade.
