Re: Help, server doesn't start

["Anibal David Acosta" <aa@xxxxxxxxxxxx>]

Some possible scenario of my last problem.

 

1.       Everything was working fine

2.       Server get out of space on the Postgres installation disk

3.       Some body try to stop and restart the Postgres due to inconvenientes with related services (ignoring the out of space problem)

4.       Postgres server doesn’t respond to the windows service STOP command and this people kill postgres processes

5.       The “Some body” try to start again the postgres service, Postgres maybe try to repair last abrupt shutdown but has no space to do anything

6.       Steps 4 & 5 maybe was repeated many times

 

We plan to upgrade to version 9.1, do you know if file result of the pg_dump in 8.3 can be restored in 9.1?

 

 

Thanks!

Yes, we must upgrade.

The value of the shared_preload_libraries is

 

shared_preload_libraries = '$libdir/plugins/plugin_debugger.dll'                               # (change requires restart)

Change that to:

shared_preload_libraries = ''

(two single quotes, not a double quote)

It's unlikely that the PL/PgSQL debugger plugin is the issue, but since it's repeated in your logs, it's worth a go.

 When I login into the server the disk used by Postgres installation was without space (0Bytes available).

 

OK, so you probably do just have xlogs that're cut short. So long as nobody tried to "fix" the problem by deleting things out of the PostgreSQL data directory I expect you'll be OK.

AFAIK Pg is supposed to recover gracefully from out-of-disk situations, but this _is_ quite an old version.

I wonder if there are any out-of-disk tests in the Pg unit tests? It'd be somewhat tricky to automate testing for, but really good to do if it's practical. Something for my bored-weekend TODO I guess, even if it's just a standalone test set.

Right now I am making a file-level copy of the entire postgres folder in order to run some corruption recover method

Great.
