Re: Postgres crash? could not write to log file: No space left on device

Yuri, You're sure the pg xlogs are going where you expect them to? Have you fine-tooth-combed your conf file for log file-related settings? Log files may well be directed to fs other than /data/postgres (as is common in our environments, e.g.)

Do a $ df -h on the various FSes involved...

Are you using Solaris 10 ACLs? Dig deeper on Tom's point on user-specific quotas. ZFS in use? Various quota settings under Solaris can get you really unexpected mileage.

Subject: [BUGS] Postgres crash? could not write to log file: No space left on device

Dear All, I have the following issue on Sun Solaris 10. PostgreSQL version is 9.2.3. The wall logging is minimal and no archiving. The DB restarted several time, the box is up for last 23 days. The PostgreSQL installation and files under /data/postgres that is half empty. Is it some other destination that might cause the problem? Can I log the space consumption and directory name where the problem is happening by some debug level or trace setting?
