Обсуждение: Postgres database is not logging any messages after the reboot
Hi The server that hosts our production postgres databases had to be rebooted last night as the file systems got remounted as read only. After the reboot we re-started the databases but now nothing is getting logged into the pglogs. Can you please assist us in figuring out the problem and help resolve it. Below listed are the error messages in the /var/log/messages file due to which we had to reboot the server. This is a linux x86-64 server. Your prompt response will be highly appreciated.

Uh, I don't see the problem? That looks like a perfectly normal
crash-recovery process, and it certainly doesn't seem to be the case
that "nothing is getting logged". What were you expecting to see?

Hi Tom
After the server reboot nothing is getting logged by the postgres
database into pg_log like messages about archived log, autovacuum,
panic, alerts etc. The alerts from the pglogs get forwarded to our cell
phones and since no messages are getting logged we will not get notified
in case of a problem with database. This is the first time we have seen
this strange behaviour. Your help in resolving the issue will be highly
appreciated.
Thanks

Sounds to me like you changed your logging settings...

When a filesystem is automatically remounted read-only by the operating system, it's because serious trouble is ahead. Rebooting to remount read-write seems a recipe for disaster unless you have corrected the problem. This may be a Linux kernel bug, a disk/cable/controller failure, or something else. -- Alvaro Herrera Valdivia, Chile ICBM: S 39º 49' 18.1", W 73º 13' 56.4" "The ability to monopolize a planet is insignificant next to the power of the source"
