【以下的问题经过翻译处理】 我们最近将位于US-EAST-1的Postgres RDS实例从db.m5.4xl修改为db.m6i.4xl。自从修改之后,我们注意到Postgres错误日志中出现了archive/WAL错误。这个实例运行的是Postgres 10.21版本。
例如:
2022-10-30 22:10:48 UTC::@:[359]:LOG: archive command failed with exit code 1 2022-10-30 22:10:48 UTC::@:[359]:DETAIL: The failed archive command was: /etc/rds/dbbin/pgscripts/rds_wal_archive pg_wal/0000000100000AE000000082
2022-10-30 22:28:04 UTC::@:[359]:LOG: archive command failed with exit code 1 2022-10-30 22:28:04 UTC::@:[359]:DETAIL: The failed archive command was: /etc/rds/dbbin/pgscripts/rds_wal_archive pg_wal/0000000100000AE000000086
(当然,文件名每次都会变化)
这些错误可能频繁地发生,每隔几分钟或几个小时就会发生。这是RDS实例中的错误还是我们需要解决的问题?
