Need help to restore database

Hi all,

we are facing with a struggle problem with PostgreSql database production.

A client system based on pgsql is down because the database raise an error message like “ no left space on device”. We have deleted some log files on this machine and after a system restart the db (and the system) was up&running. After two days the database has crashed again. Looking the postgres log there was an error on xlog file (I have inspected the directory pg_xlog and no files I found it). I’ll try to re-build the xlog file with pg_resetxlog. The utilities has created a new xlog file, the postmaster process run, but any command pg_dump, etc I try to execute failed. The system respond that there are not database in the system. Can anyone help us ?

Thanks in advance
