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

Dear Expert,

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

-bash-4.2$ df -h
