I'm still confused about the disk space, even more so now that more servers and figures of 1Gb and 15Gb have joined the party. Presumably this: > 3.6M ./1 > 3.6M ./16975 > 51G ./95186722 > 4.8M ./4830693 > 51G . is the output from some $ du command. And is this > -rw------- 1 postgres postgres 16K May 5 12:50 219436402 > -rw------- 1 postgres postgres 16K May 5 12:50 219436401 > -rw------- 1 postgres postgres 16K May 5 12:50 219436400 > -rw------- 1 postgres postgres 16K May 5 12:50 219436399 > -rw------- 1 postgres postgres 34M May 5 12:50 219436274 > -rw------- 1 postgres postgres 42M May 5 12:50 219436273 > -rw------- 1 postgres postgres 43M May 5 12:50 219436272 > -rw------- 1 postgres postgres 42M May 5 12:50 219436271 > -rw------- 1 postgres postgres 34M May 5 12:50 219436270 > -rw------- 1 postgres postgres 42M May 5 12:50 219436269 > -rw------- 1 postgres postgres 42M May 5 12:50 219436268 > -rw------- 1 postgres postgres 51M May 5 12:50 219436267 > -rw------- 1 postgres postgres 34M May 5 12:50 219436266 > -rw------- 1 postgres postgres 51M May 5 12:50 219436265 > -rw------- 1 postgres postgres 15M May 5 12:50 218478745 > -rw------- 1 postgres postgres 11M May 5 12:50 218478744 > -rw------- 1 postgres postgres 10M May 5 12:50 218478743 > -rw------- 1 postgres postgres 13M May 5 12:50 218478742 > -rw------- 1 postgres postgres 440M May 5 12:50 216081969.1 the output from some $ ls command on /usr/local/pgsql/data/base/95186722? You say there is nothing else in that directory, but those sizes don't add up to 51Gb so something is messed up somewhere. Maybe this is nothing to do with postgres and a reboot and/or fsck of the disk will fix everything. -- Ian.

And in other servers these table space sizes are now at 1.0G, for an example there is about 15of them which makes about 15G. > > -rw------- 1 postgres postgres 16K May 5 12:50 219436402 > -rw------- 1 postgres postgres 16K May 5 12:50 219436401 > -rw------- 1 postgres postgres 16K May 5 12:50 219436400 > -rw------- 1 postgres postgres 16K May 5 12:50 219436399 > -rw------- 1 postgres postgres 34M May 5 12:50 219436274 > -rw------- 1 postgres postgres 42M May 5 12:50 219436273 > -rw------- 1 postgres postgres 43M May 5 12:50 219436272 > -rw------- 1 postgres postgres 42M May 5 12:50 219436271 > -rw------- 1 postgres postgres 34M May 5 12:50 219436270 > -rw------- 1 postgres postgres 42M May 5 12:50 219436269 > -rw------- 1 postgres postgres 42M May 5 12:50 219436268 > -rw------- 1 postgres postgres 51M May 5 12:50 219436267 > -rw------- 1 postgres postgres 34M May 5 12:50 219436266 > -rw------- 1 postgres postgres 51M May 5 12:50 219436265 > -rw------- 1 postgres postgres 15M May 5 12:50 218478745 > -rw------- 1 postgres postgres 11M May 5 12:50 218478744 > -rw------- 1 postgres postgres 10M May 5 12:50 218478743 > -rw------- 1 postgres postgres 13M May 5 12:50 218478742 > -rw------- 1 postgres postgres 440M May 5 12:50 216081969.1 > > > > > > > > > > > > > -----Original Message----- > From: Kevin Grittner [mailto:Kevin.Grittner@wicourts.gov] > Sent: Wednesday, May 05, 2010 3:59 PM > To: pgsql-admin@postgresql.org; Khangelani Gama > Subject: Re: [ADMIN] Table space grow big - PostgreSQL > > Khangelani Gama <Khangelani.Gama@ucs-software.co.za> wrote: > >> There is a script that runs once a month > > Most likely that should be daily, or at least weekly. > >> "REINDEX TABLE ${table}" >> "VACUUM FULL VERBOSE ${table}" >> "VACUUM ANALYZE ${table}" > > That's the wrong order.
