Re: [GENERAL] No space left on device - Mailing list pgsql-general

Cleaning pg_log should be enough to be able to start your postgres instance. However, it will let you with almost no
spacefor your database to grow. If you have some tables with information you can delete, that can free up space. 

Unless most of your database information is "volatile"(case in which you should implement an automatic cleanup cron),
theonly remaining option is to get a larger disk for your vps.

With correction: pg_log consumed 897 MB only

Cleanup some space on that device. Maybe your "pg_log" folder has some space to free. If that doesn't helps, you may
needto forcefully add more space. There's not really much alternatives there.

Dear Expert,


My PostgreSQL database got down due to no space left on my mount point /dev/vdb1 where my data directory are available,
pleasesuggest what's the best solution to resolve this issue. I am also not able to start my database again due to no
spaceavailable. And right now, we don't have any further space to add in this mount point.
