Bugs or Error?

Hello,

I just want to know if this is a bug or just an error to my postgrsql.

What i did is i install the postgresql 7.2.1mlx for libs, posgresql, and
server

using Linux Red Hat 8.0.

Then i created a "postgres" and do the following;

su postgres
psql template1

then i try to create database "inventory" in template1=# then
this message appear.

"NOTICE:  write error may be permanent: cannot write block 10 for 22892/1249
ERROR:  cannot write block 10 of 22892/1249 blind: No such file or
directory"

How this happen?
