Hello,
I posted yesterday about a corrupt index. I'm continuing to
experience problems. I know that part of my problem is that the
databases have not been vacuumed as they should have been. I've
tried to vacuum them but it's not working. The message I'm getting
is as follows:
vacuumdb: vacuuming database "km"
NOTICE: number of page slots needed (2275712) exceeds max_fsm_pages
(200000)
HINT: Consider increasing the configuration parameter
"max_fsm_pages" to a value over 2275712.
The problem is I've found the max_fsm_pages parameter in the
postgresql.conf file, but changing it doesn't seem to be having any
effect. So I'm going to ask some questions that are probably pretty
silly, but I hope you'll help me. First of all, perhaps the
postgresql.conf file that I am editing may not be the one that is
being read when the database server starts. There are several
postgresql.conf files on this system. How do I tell which one is the
one being read?
The max_fsm_pages parameter says what the minimum setting is in the
file. Is there also a maximum?
I can't back up my database with the error right now, because of the
error. I have a backup but I'm afraid to restore it. I feel like I
have many indices that are bloated and I want to get the databases
vacuumed before I start trying to create and load a new database.
I'm concerned that there won't be enough index space for the system
to sort and copy the indices.
Please, help.
Carol

You have to restart the database.

It is limited by your shared memory but consider that is not your
problem. Your problem is you don't vacuum enough. My suggestion is to do
the following:
Up the max_fsm_pages a considerable amount
Restart
Vacuum the entire database
backup
reinitialize with backup
make sure you are vacuuming properly.
Sincerely,
Joshua D. Drake

Oh, yes. I have restarted it several times - or at least I thought
that I did. Actually, it's not stopping. I grepped for "post" after
I did the stop and it is still running. I really don't like the idea
of issuing the kill command on the database processes. Is there
another option?

Does this do an orderly, safe stop? Also do I then bring it back up
with the usual command?
Thanks,

"Three different shutdown methods can be selected with the -m option:
"Smart" mode waits for all the clients to disconnect. This is the
default. "Fast" mode does not wait for clients to disconnect. All
active transactions are rolled back and clients are forcibly
disconnected, then the server is shut down. "Immediate" mode will
abort all server processes without a clean shutdown. This will lead to
a recovery run on restart."

Hi, Again.
I tried this and got the same message. It is as follows:
-bash-3.00$ /opt/csw/postgresql/bin/pg_ctl -D /dbpdisk/postgres/
prod_823 -m fas
t stop
pg_ctl: PID file "/dbpdisk/postgres/prod_823/postmaster.pid" does not
exist
Is server running?
Are there other ideas?
Carol

Carol, what does:
ps -ef | grep postgres
return?
If postgres is really running, there should be a postmaster process that
shows which directory it's using as the DATA directory. It'll look
something like this:
postgres 24080 1 0 09:49 ? 00:00:07 /usr/bin/postmaster -p
5432 -D /var/lib/pgsql/data
If there isn't a postmaster, it's possible someone started postgres with
the -D option directly.
If you have multiple postgres server's running on the same machine,
you'll see multiple postmasters.
BTW: What operating system is this running under? If linux, which
distribution?

Hi, Jeff,
Here's the output from the command.
-bash-3.00$ ps -ef | grep post

I running under Solaris 10. I don't have anything that looks exactly
like what you here, but the postgres has got to be running. I can go
in as the postgres user connect to different databases and select
data from them. This installation was loaded by my colleague using a
product called Blastwave hence the csw directories.
By the way, and not incidentally, thank you for the help.

Looks like pid 9629 is the parent of all of them, so if you simply:
kill 9629
they should all exit gracefully. You can check this with the same ps
command.
Then you should be able to: "pg_ctl -D /dbpdisk/postgres/prod_823 start"
as the postgres user to start it back up.
I think you might want to have a look at the /etc/init.d/postgresql (or
whatever the startup script is) because it doesn't look to be using
pg_ctl to start postgresql since the pid file was missing or ask your
colleague how it was started in the first place. I'm not sure on
Solaris if the ps output gets changed like it does in linux to reflect
the processes role. In linux those would probably look more like this:
postgres 2525 1 0 May02 ? 00:01:04 /usr/bin/postmaster -p
5432 -D /var/lib/pgsql/data

Carol,
Do the following in psql:
show config_file;
You should get some output like so:
config_file
-------------------------------------
/var/lib/pgsql/data/postgresql.conf
(1 row)
Go forth and edit that file. :-)

I'm not sure I understand the question. max_fsm_pages is the maximum
number of pages to be used in the free space map. See Jim Nasby's
article here: http://decibel.org/~decibel/pervasive/fsm.html

What's the error? All I see in this email is a warning about
max_fsm_pages and that should not stop you from doing a pg_dump.

Jeff,
Thank you very much. I didn't know about this command. There are
lots of times this would have saved me looking it up in my
documentation. I've got a couple of different instances of postgres
running and I always have to check the docs to find out where my
config file is.
Well, the table I told everyone about yesterday won't let me run
pg_dump against it. My hesitancy comes from not knowing what the
result will be of dumping the other databases. I've had the
experience of dumping my "can of worms" out and not getting them back
in the same "can" when I was done with them. =)
Carol

What error are you getting when you try to dump that table?
