database - PostgreSQL 9: could not fsync file "base/16386": Invalid argument -

i'm trying test small postgresql setup, cobbled quick local install. however, when i'm trying create personal db createdb, chokes on errors (notably, starts base/16384 first time, , increments each time run it). know what's going on here, or if there's trivial config missed cause this? thanks, , time-critical, please respond if know anything. thanks!

updates:
i'm running on centos 5 server, apologies don't have many further details (it's shared account on server). uname -a has following output:

linux {omitted} 2.6.18-194.11.4.el5 #1 smp tue sep 21 05:04:09 edt 2010 x86_64 x86_64 x86_64 gnu/linux

i installed postgresql source from:

http://wwwmaster.postgresql.org/download/mirrors-ftp/source/v9.0.1/postgresql-9.0.1.tar.bz2

built in home directory , installed prefix=$home/local/pgsql.

here's terminal readout me attempting create user's db on fresh data setup:

i guess you're possibly running se linux system here. i'd recommend either turn off selinux , see if works, or install rpms available postgresql website.
