Hi all,
Problem:
If I use
SELECT pg_size_pretty(pg_database_size('dbname')) As fulldbsize;fulldbsize ------------ 6455 MB (1 row) If I compare this output with /var/lib/postgresql/9.0/main/base/[DBFOLDER] I have a difference of 3 GB, which I think is not normal. To make a little bit clearer what i mean: /var/lib/postgresql/9.0/main/base/43169# du --apparent-size -h 6.4G . /var/lib/postgresql/9.0/main/base/43169# du -sh 9.4G .Is such a big fragmentation a normal behavior? It's splitted to several Filenodes.
I also made a "xfs_fsr" to defrag all of this, i gathered around 1 GB back ( would be more if the tables wouldn't be written in this time ) But within some hours the fragmentation was back..
There is also no big dead tuple count in this database, it's getting a vacuum analyze every night.
Right now i am out of ideas... What do you think i could do? If you need more information i can provide. Environment: - OS: Debian Lenny - Disksize: 15GB - Filesystem: XFS - Psql: 9.0.3 thanks in advance. regards Bernhard -- Sent via pgsql-admin mailing list (pgsql-admin@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-admin
